Looking at https://www.mongodb.com/docs/manual/changeStreams/#change-streams-with-document-pre--and-post-images, it suggests toLimit the document size to 8 megabytesI wonder how can we achieve that with transactions, where we don’t know the full document size until the commit time.",

"text": "Hi @Yang_Wu1,I wonder how can we achieve that with transactions, where we don’t know the full document size until the commit time.The document size limit applies to each document in a multi-document distributed transaction (MongoDB 4.2+), not the overall size of the transaction.If individual documents you want pre-images for are likely to approach 8MB or more, I would review the reason for document growth and reconsider your data modelling approach. Large documents are often due to anti-patterns like massive arrays or bloated documents.Alternatively you could avoid using both post-images and pre-images for a collection which has large documents and consider:Requesting only post-imagesRequesting only pre-images in the change stream output and fetching the current documentDisabling pre-images for collections with large documentsRegards,\nStennie",

"text": "My question concerns the amount of read vs write units that register on MongoDB Atlas after updateOne operations on documents in a bucket pattern.I have a stream of steady IoT data for measurements at minute intervals. I decided to bucket these measurements daily and so they are stored in documents that have a startDate and endDate field compartmentalising each day. Here’s a representative schema:Every time I updateOne, I use the $push aggregation to add a measurement to the relevant array above (note that I am using upsert: true). If the bucket does not exist, I insert it, and use the $setOnInsert aggregation to set some field.\nHere’s the full query:Since updateOne with upsert does not retrieve the document that it updates or inserts, there should only be write units registered on MongoDB Atlas.Every time updateOne is triggered, the expected write units are registered, but , I also see a much bigger amount of read units that seem to grow proportionally with the size of the measurements array. This is proof that the updateOne operation is in fact also triggering reads for some reason.Here’s a screenshot of this from my logs. As you can see, at the beginning of each day when the bucket has no measurements, the read units are much less and they can be seen to grow throughout the day as measurements are recorded at minute intervals.Why are reads metered that are proportional to the size of a nested array when I am only performing an updateOne (with upsert) operation on such a document?",

"text": "Hi @Iuliu_Teodor_Radu welcome to the community!Since updateOne with upsert does not retrieve the document that it updates or inserts, there should only be write units registered on MongoDB Atlas.The updateOne operation still needs to read the document. This is because it needs to apply the update operations on an existing document, which it cannot do if it doesn’t have the document to start with.From the pricing page, an RPU is multiplies of 4KB in terms of document size:If a document exceeds 4KB or an index exceeds 256B, Atlas covers each excess chunk of 4KB or 256B with an additional RPU.Thus if you can isolate the RPU for this update operation, I think you should find that the number of RPU consumed corresponds to the size of the document divided by 4KB.Best regards\nKevin",

I was only using it for staging some devices, but even that won’t be scalable.\nThanks again.All the best,\nTeodor",

Most of us use document stores like MongoDB for the fundamental tenet - of being able to have the flexibility of schemaless/extensible schema documents. Given that, the attribute pattern seems a workaround (IMHO). Put another way, it could be done with a regular(non document) database with a large vertical table that stores the attributes as keyvalue pairs (parent object id, attribute id, value as string ) without a document store?Size of indexes - If I don’t need all my attributes indexed potentially, but only some of them only (say 20-30% attributes ), the attribute pattern wouldn’t let me do that, leading to large indexes ?Doesn’t handle nested documents well ( If I have a document with flexible attributes and it has a nested document with flexible attributes, I cannot use this patterns for any arbitrary level of or type of nested document )Sample Document For this discussion with attribute pattern",

We can therefore make the following observations:Keep in mind that databases, MongoDB included, are usually most effective at using a single index per data source (collection in this situation) per operation. The only compelling reasons to have a single field index on {created_date2: 1} would be if it is a TTL index or if you are issuing queries where created_date2 is the only or most selective predicate. You should consider dropping such an index (and incorporating that field in a compound index per the third point above) if none of these conditions apply in your situation.",

Is this the correct approach? will this work?\nMy original plan was to add the new field equipmentId and remove the old one (see the $unset call at the end) but I cannot get that to work when working with lists of lists.\nAny advice either way would be greatly appreciated.\nI would prefer to add the new field the remove the old one WITHOUT having to specify every other field in each device object as some of those may contain more nested objects.",

For triggers, you can use Realm CLI or Atlas App Services Admin API. You can utilise a combination of API requests, mongosh scripts, etc to create an environment for fresh use every time.You can also refer to this article on “How to Build CI/CD Pipelines for MongoDB Realm Apps Using GitHub Actions” for more insight. Which method ultimately is best for your use case really depends on your specific situation, and perhaps your existing tooling.Regards,\nTarun",

The $search or the $searchMeta stage must be the first stage inside the $lookup pipeline. It helps in querying from different collections together.Although this might help in your use-case but if you are doing this frequently then doing a $lookup for every single request might get expensive and might not be very performant so as an alternative you may be interested in checking out Materialised views which is a pre-computed aggregation pipeline result. On-demand materialized views are typically the results of a $merge or $out stage. It could provide a performance boost at the cost of extra storage space, and you will also need a way to trigger the data refresh so that the view remains up to date.most of the heavy lifting is done by MongoDB.Also, what is the heavy lifting you are looking for? Is it raw speed, efficiency in terms of index usage? Could you please help me with this?Regards,\nTarun",

It sounds like you are expecting the order of result documents to match insertion order, which is only guaranteed for the special case of a capped collection (see: What is the default sort order when none is specified?).If you are sorting based on date components as string values, the lexicographic order will be be based on string comparisons (characters and length) as @steevej suggested.However, it looks like you have a proper date field you could use for sorting (which should also obviate the need to duplicate the data information in various string formats).To confirm this isn’t an issue with the results returned by your query, you could also try searching for the documents presumed missing from 2016-01-02.Regards,\nStennie",

Use create instead to copy it into this Realm.I also tried to only declare the object type only in the instance that I want to move the object into, however, in that scenario, I can’t query the objects from the old realm because the object is not declared in there anymore…Would appreciate some help!\nThanks in advance ",

"text": "Good day. I’m working on some first steps in my development so mongo is still somewhat complex.\nNevertheless, I got to a point in my C# console application where in it’s simplest format takes data from a local SQL DB and pushes the documents to MongoDB. I believe I’m using an M2 basic elastic environment while I practice so maybe that’s my problem?In one example I have ~190K documents to publish to MongoDB. It can be more or less but this is a case I’m using. at first I tried to push it all, which is several years of data, but that didn’t work. I figured maybe I surpassed the 16MB doc size limit so I broke it down into a throttle by years. In this case it’s 4 years of data. I feel using batching is how I’ll do most of my writes at this point.This is an initial load so it has a larger dataset, which allows me to flesh out these limits. In production the data sets are relatively tiny. i.e 200-300 records a day.Essentially\nI’m generating a list of WriteModels as such:var listWrites = new List<WriteModel>();And publishing one year at a time to throttle it as such:var result = await _salesCollection.BulkWriteAsync(listWrites);A year is roughly 40-55K records(documents).What I noticed first was that 2019 failed with 56K records which was the largest but subsequent (2020, 2021,2022) succeeded? They were all smaller (~40K records).Then I changed from yearly to a throttle number (100K documents) and published chunks.\nIn this case a total of 193,519 documents the first 100K got in as expected, albeit slow, but the next 93,519 didn’t make it with the following exceptions.Exception:\nAn exception occurred while receiving a message from the serverException Inner Message:\nAttempted to read past the end of the stream.Inner Exception.Stack:at MongoDB.Driver.Core.Misc.StreamExtensionMethods.ReadBytesAsync(Stream stream, Byte buffer, Int32 offset, Int32 count, TimeSpan timeout, CancellationToken cancellationToken)\nat MongoDB.Driver.Core.Connections.BinaryConnection.ReceiveBufferAsync(CancellationToken cancellationToken)I haven’t managed to find an answer to help me understand what’s happening. It’s referring to an error “receiving a message”, but I don’t know exactly what the message is or how to trap it and resolve it? It’s talking about CenellationTokens etc but still not clear.It feels like maybe I’m hitting a limit as 100K sounds familiar from documentation but I’d like to understand what sort of throttling I need to implement and on what limits?At this point I’m ok with slow performance but for it to just fail? idk.I feel this is “basic” for the pro’s out here and over time I’ll get more exposure but MAN I’m in trouble if I can’t even do a write without hitting a wall Thanks in advance\nCPT",

Nevertheless I want to ask it myself because I couldn’t get my head around it.I have an app wich uses a Team partition strategy for chats, a private (user) partition strategy for personal data and a “public” partition value for data that everyone can see but only the owner can write/change.My first question is about the user. If I don’t want to share all the data from the user in the “public” partition, I would need to create two similar collections in my schema (one collection for the publicUser and on for the privateUser). Is there a simpler way than creating two collections that are actually the same (beside the values)?I understand Realm that every Realm partition I open in the app, saves all the data from that partition on the device. That would mean for my public partition, that every user that creates data in the public partition, would force all the other users to save the created data on their local device as soon as the app opens the “public” Realm.If that’s correct, then how is an app with Realm Sync and MongoDB like Airbnb possible, which has a lot of public data that can’t be stored locally on devices. Is there a solution to have an only Online partition OR to never save data on the device when there is only a read permission?Thanks!",

I am now wondering what would be the “best” way to remove subscriptions in a SwiftUI app.For example, I have an iOS app where one tab is showing user-generated content (the PUBLIC part I was referring to earlier) that I would like to purge from user’s local storage at some point. At the moment, I am trying to add subscriptions through the MyPublicTab.onAppear() and remove them with MyPublicTab.OnDisappear(). But unfortunately, it looks like removing subscriptions takes a while, which puts the app in an inconsistent state, if the user navigates quickly through the app. The worst case is to have a “clear the cache” option, but any better suggestion is appreciated.

"text": "Hi @Sonisan,Yes, adding and removing subscriptions that move potentially large data sets is not ideal for performance… You can await for the subscription to be updated, but that’s not great user experience either.Perhaps you should devise a subscription that can trickle data in and out in small chunks, that would go (almost) unnoticed. For example, you can always be subscribed to the PUBLIC part, but put a time limit (say, since last day, or last visit), and update the limit (up or down) only when the user gets near to it. Nudging subscriptions, instead of removing and creating them, should be much more efficient.Take all the above with a grain of salt, of course, as Flexible Sync is relatively new, in its current form: for more information, you can read the technical articles from one of the engineers that built it, there are a lot of hints you can take from there!",

You can set up a forward tunnel from the Windows machine to the Ubuntu machine, or a reverse tunnel from the other direction.

"text": "Hi @Sercan_Ersan,Thanks for clarifying those details. There currently isn’t an Atlas alert that can be created for when an index creation is submitted. If you would like this feature to be added, I would suggest you to file a feature request via feedback.mongodb.com being sure to include all your use case details. From that platform, you will be able to interact with our Product Management team, keep track of the progress of your request, and make this visible to other users.Is there a way for me to insert this output into a collection?One idea based off what you have provided from the output screenshot is to log the namespace details & index details (from the output) on the application side and insert them to a collection so that you can use to monitor indexes. This could then be made to be a CRON / scheduled job so that you can check every now and then to verify the appropriate indexes are in place. Additionally, you can consider limiting access to this collection to only certain database users. Please see Configure Custom Database Roles for more information on this.However, this leads to another problem - How or when to know when an index is removed?I believe it may be better to solve this from a workflow perspective. One suggestion could be:Allowing your developers to create indexes in the dev environment and have some auditing to pick up when a new index is created. Since you’re on MongoDB Atlas, you could Set up Database Auditing to audit createIndex and dropIndex actions although this feature is only available on M10+ tier clusters. You can then retrieve the mongodb-audit-log’s and filter for if these actions have occurred periodically.Example:\n\nimage832×690 14.5 KB\nDisallow creating indexes in the production environment outside of an approved deployment process. I.e. Only indexes that you’ve approved (through an internal process) from Dev can be created on Production.Of course, all the above would depend on your use case and requirements. Would you be able to advise if the indexes are being created manually or via code?Regards,\nJason",

When sorting on a field which contains duplicate values, documents containing those values may be returned in any order.If consistent sort order is desired, include at least one field in your sort that contains unique values. The easiest way to guarantee this is to include the _id field in your sort query.If no sort() is supplied then MongoDB will pull back the data in the most efficient manner possible, wether that’s pulling data as stored in memory or disk.

This means:You could do this by hand with enough time, but it’s a lot easier to use either a web-based tool or use a programming language for this.For example, this PHP one-liner can solve the puzzle:For bonus points, the solution contains a joke — do you get it?

"text": "Today’s challenge is information. This is a forensics challenge (with some bonus crypto too; there’s a clue ;)).Digital Forensics is a branch of forensic science encompassing the recovery, investigation, examination and analysis of material found in digital devices.This challenge will be some of that on a smaller scale: trying to look at a single picture and find the flag that’s somehow hidden within.You’re given the following ADORABLE image: cat.jpgThis image clearly has both fur and tech, but WHERE is the flag…? HintEXIF ( Exchangeable image file format) is a standard for storing metadata about an image. It’s commonly used to document things like the date and time of its creation, what camera settings were used, and specified copyright information about any given photo.WalkthroughInterestingly, if you try and view the metadata with a standard EXIF viewer tool such as exif or macOS Finder, it chokes on invalid input. I found two ways around this:In any event, you’ll see that the “license” property is set to an interesting-looking string: <cc:license rdf:resource='cGljb0NURnt0aGVfbTN0YWRhdGFfMXNfbW9kaWZpZWR9'/>This is suspicious because you’d expect this to be a human-readable string; something like “Public domain” or “CC BY-NC.” This indicates the use of some kind of encoding.A common type of encoding used on the web, especially for binary objects such as images, is Base64. It encodes binary data into text so it can more easily be sent around (for example, as an email attachment). If you’re ever doing a challenge that has a similar string of gobbledygook (alphanumeric characters, and the number of characters is divisible by 4), and especially if that gobbledygook ends in = or ==, it’s a good bet it’s Base64 encoding.However, that which can be encoded can also be decoded. Once again, a PHP one-liner can solve this one:<?php echo base64_decode('cGljb0NURnt0aGVfbTN0YWRhdGFfMXNfbW9kaWZpZWR9'); ?>Or, you can use a web-based tool such as https://www.base64decode.org/",

This will be a cinch!”And indeed it starts the same way—with what even looks like the exact same web page!—but this one requires a bit more poking around.HintFor this one, you’ll need knowledge about other common files found on web servers, not just those embedded in the page itself.Beyond that, read the clues the puzzle gives you carefully; each one contains a distinct hint to point you in the right direction.WalkthroughJust like yesterday’s challenge, you can start piecing the flag together by viewing source on the HTML and CSS files and looking at the code comments.However, you’ll hit a wall when you get to the JS file. Instead of the comment giving you a part of the flag string like before, it will instead ask a cryptic question:/* How can I keep Google from indexing my website? */There is a Robots exclusion standard that exists as a means to communicate with (well-behaving, non-malicious) web crawlers about which areas of the website should and should not be processed or scanned.An example file might look like the following, if it wanted to tell ALL robots not to scan the “private” directory:(Ironically, Google’s own documentation states in bold, red letters: \" Warning : Don’t use a robots.txt file as a means to hide your web pages from Google search results.\" A better approach is a noindex metatag, as that removes the page even if it’s linked to from somewhere else vs. crawled by Google.)ANYWAY. Once you load that file, you’re given another piece of the flag, as well as another cryptic clue:# I think this is an apache server... can you Access the next flag?Apache is a very common web server, and this clue refers to an Apache configuration file that lets you make configuration changes on a per-directory basis, overriding the default Apache configuration found in httpd.conf. You can do things in there such as require a password to access the directory contents or re-write URLs.Once you load THAT file, you’re given another piece of the flag, as well as another cryptic clue:# I love making websites on my Mac, I can Store a lot of information there.Unlike the others, this one isn’t actually a common file found on web servers… at least, not on purpose. Desktop Services Store files are found inside every directory accessed by macOS Finder, and they contain information about the containing folder, including what file names are inside it [!], which can be parsed and crawled by an attacker to find files they ought not have access to.They are also the bane of many web developers’ existence, because they are dotfiles, which means they are hidden by default and thus easily accidentally committed to version control or uploaded to a web server. At any rate, throw that file name at the end of the URL and you’ve got the final part of your flag. ",

Which means our key needs to be exactly that long.Ah, but wait, the next check:… indicates that not just ANY 32 character string will do; it has to start with exactly the same characters as there are in key_part_static1_trial, which MEANS the first few characters are picoCTF{1n_7h3_|<3y_of_ That’s a great start!OK what’s next? A bunch of lines like this:This is moving one character at a time through the next part of the key (those Xs), and comparing its value. To what? We recall from above that username_trial is “FRASER”. This code takes that name, runs it through a SHA-256 hash function to turn it into a hexadecimal string, then finds the character in the Nth position. (And actually, N + 1 since indexes in Python, like many other languages, start counting from zero.)If you run “FRASER” through a tool like SHA256 Online, you’ll see it results in the following string:92d7ac3c9a0cf9d527a5906540d6c59c80bf8d7ad5bb1885f5f79b5b24a6d387(Note: SHA-256 hashing will always result in the same output for any given input. This is why it’s extremely important to “salt” your hashes so that they cannot be easily reverse-engineered, e.g. when used for things like one-way encrypting passwords.)Reading through the remainder of the check_key() function, you can see that it wants the character in the hash string in the 5th position (“a”), then the 6th (“c”), then the 4th (“7”), … and so on.Once you’ve figured that out, replace “xxxxx” in key_full_template_trial with what you derived, and you have both your flag and your license key!

Try and notice patterns. Are the numbers within a certain range? Do any of the numbers repeat? What might those correlate to?Under the hood, computers can’t inherently deal with text, only with numbers. So when we want to send a text character, such as the letter “a” or the symbol “_”, that needs to be encoded so that the computer can read and transmit it.A very common method of encoding is ASCII (abbreviated from American Standard Code for Information Interchange). Each character is assigned a numeric value from 32-126. (Why starting at 32? Because the numbers prior to that are for non-printable control characters such as “end of file” or “line break.”)Once again, this challenge can be solved by either manual conversion of numbers to characters found in an ASCII table, or, you can use an online tool such as Convert ASCII Codes to Characters.(Warning: The line breaks between the different numbers can really throw off results in automated converters in my experience.

However, it is possible that repeatedly running the script may lead to multiple copies of the script to open connections to the database and thus trigger the warning. Are you seeing any kind of pattern when this warning was triggered, e.g. an especially busy time, during certain development phase of the app, or other patterns that may coincide with the warning?Also, for MongoDB, we generally recommend not to open/close connections after every use instead use connection pooling to maintain a cache of open, ready-to-use database connections maintained by the driver. Your application can seamlessly get connections from the pool, perform operations, and return connections back to the pool. Connection pools are thread-safe.Please refer this documentation for more information on connection pooling.Tarun",

Is there a way to instantiate the Realm within a NitoAsyncEx Context, then later subscribe for notifications to the Realm in a way that I do receive them? Or is there a way to instantiate the Realm without Nito.AsyncEx, but the LoginAsync, PartitionSyncConfiguration , GetInstanceAsync can be done (via a synchronous wrapper, perhaps?) in the proper order and the results from the two async methods (LoginAsync, GetInstanceAsync) are returned without a thread deadlock on the UI Context?",

That should not be necessary and is probably freezing your app while the login/download is happening. Instead what you could do is something like:That way you setup everything on the UI thread and can use it in your pages/viewmodels. If you don’t want to do that, then you can still use Nito.AsyncEx, but don’t set the Realm you just downloaded to your MongoRealmServices.Realm. Instead, in the page/viewmodel, you just use the config to open a Realm instance synchronously.If you want a more thorough deep dive in best practices when using Realm in Xamarin.Forms (although that’s applicable to any xaml-based UI framework), you can check out this blog post by @papafe. It goes into a lot of detail about structuring your app but also compares and contrasts to a SQLite-based app, so if you have experience with that, it will help even more. It does focus on the local database + an http-based API, but the main principles still hold as after the authentication part, there’s pretty much no difference between using a local or a synchronized Realm.",

Unfortunately, I can’t really adapt it to my stack (Mongoose, typegraphql, typegoose, express, apollo), in other word: it doesn’t work for me Here is my code for my server if you want to see what I tried:Thank you so much Have a good night dev!",

"text": "Hello,We’re using MongoDB Atlas, and we’re already using ElasticSearch.However, we face a lot of problems with the added burden of syncing data and schema changes between MongoDB and ElasticSearch, plus the extra cost of maintaining an ElasticSearch self-hosted instance.We’re seeking the best full text-search across multiple collections, with suggestions and auto-complete functionality.We are now considering MongoDB Atlas Search.Here are the main issues we face with Atlas Search:1 - Atlas Search requires Searching to happen as the first stage in an aggregation pipeline. This puts a limitation because sometimes we want to do an aggregation first (lookups, match, etc) then do the search on the data from the previous stages. Does anyone know if this is still a limitation or has things changed ? And what is the best approach in this case ? i.e. How can we search across multiple collections for example using the same search query ?2 - Does Atlas Search provide the same auto-complete functionality as ElasticSearch ?3 - Does Atlas Search provide the same search-suggestions functionality as ElasticSearch ?Many thanks for your time and support",

This puts a limitation because sometimes we want to do an aggregation first (lookups, match, etc) then do the search on the data from the previous stages. Does anyone know if this is still a limitation or has things changed ? And what is the best approach in this case ? i.e. How can we search across multiple collections for example using the same search query ?As of MongoDB version 6.0, you will be able to run cross-collection searches. You may find the following documentation / pages useful regarding this:2 - Does Atlas Search provide the same auto-complete functionality as ElasticSearch ?As per the autocomplete operator documentation:The autocomplete operator performs a search for a word or phrase that contains a sequence of characters from an incomplete input string. You can use the autocomplete operator with search-as-you-type applications to predict words with increasing accuracy as characters are entered in your application’s search field.Were there more specifics regarding what functionality you were after specifically or does the above described (or the documentation as well) cover the core functionality you are after with Atlas search specific to auto-complete?3 - Does Atlas Search provide the same search-suggestions functionality as ElasticSearch ?Could you provide some further use case details regarding this question? E.g. Is the search input “Naw York” and the expected output (or suggestion) “New York”?There are a few features which may provide the functionality you are after but it will depend on the use case:Having said those, I would like to state that I’m not an expert in ElasticSearch (we are a MongoDB forum after all ). Regarding Atlas Search, one resource that might be of interest to you is the tutorials on Atlas Search that should provide a general overview of Atlas Search’s capabilities as of today.Regards,\nJason",

"text": "Hello @Daniel_Lux and welcome to the MongoDb community!!MongoDB time series collections are basically a non materialised views under system.buckets backed by the internal collections. Querying in the time-series collection, utilises this format and returns results faster.The query optimisation on the time series collection works differently than the normal collection and hence, the db.<collection>.explain().<query> works on the underlying collection rather on the non-materialised views being created.The time series makes use the clustered index created by default and to further increase the performance, you can manually add the secondary indexes to the collection.However, for the above dataset provided, I tried to reproduce the issue on the MongoDB version 6.0 with dataset of around 1 GB of dataset and observed the following:Using the query :db.sample.explain().aggregate([ {$sort:{timestamp:-1}}, {$limit:10} ])This query takes around 16 seconds to respond with the appropriate documents and uses the COLLSCAN to fetch the documents which explains the delay.However, using the range query as:db.sample.explain().aggregate([ {$match:{timestamp:{$gte:ISODate(“2021-01-10T10:02:18.242Z”)}}}, {$sort:{timestamp:-1}}, {$limit:10} ])subsequently reduced the execution time for the query and makes use of the clustered Index.This further explains that, the range query targets the buckets and unpacks and produces the output, however, query without the range, would basically unpack all and give the output documents which explains the COLLSCAN in the execution status.For the above two query, the executionTimeMillisEstimate field value has efficiently reduced from ~16 seconds to ~8 seconds on average.\nTherefore, the recommendation would be make use of the range query to optimise the response for the collection.In conclusion, a time series collection works differently than a normal collection, and as of MongoDB 6.0, the usual query optimisation methods may not work as expected. Note however that this may change in the futureLet us know if you have any further questions.Best regards\nAasawari",

"text": "Hi @Aasawari, thank you for answering on this topic!the presented solution cuts down execution time indeed. But it seems rather inefficient to lookup all documents when they are sorted by timestamp anyway (even the clustered documents are sorted by “time window” i guess).\nMy naive approach would be to collscan the first clustered document and if the scan does not return the required amount of documents scan the next clustered document.The issue is that the data that i store is not inserted in equal intervals, so i don’t know the time range to filter first. I could store an average insertion interval for each collection i have elsewhere and use that to calculate an approriate filter first.There is one thing i noticed: your first axamples states executionTimeMillis: 16937 which corresponds to your 16 seconds execution time. The later example shows executionTimeMillis: 21277 which is 5 seconds more? Could you explain this discrepancy in more detail?Thank you for your help.Regards\nDaniel",
