The other thing that would be particularly useful to know would be about the overall problem that you are facing and the goals/outcome that you are attempting to achieve. Without that we are only going to be able to provide snippets of information which may or may not be helpful in solving your underlying issue(s).Broadly speaking, there’s nothing in the brief information that you’ve provided that looks particularly out of the ordinary or problematic. Shard filtering and merging are standard internal parts of executing queries that target more than one shard. The filtering stage is responsible for removing documents that have logically moved to another shard but haven’t been physically removed yet (referred to as orphans) and the merge stage is responsible for compiling the responses from individual shards into the single response that the client is expecting. Duration estimates are less accurate due to the manner in which they are measured which can result in rounding errors obscuring where some of the work is taking place. Stage times are cumulative, so any time spent by child stages are included in the duration of the parent stage. There is some parallelism that naturally happens with sharding, which means that the cumulative time there looks a little different. Relatedly it’s important to keep in mind that network latency associated with internal communication to process the operation will also be captured in various places for the reported execution times.We cannot say anything meaningful about the overall duration of the operation (seemingly about 0.85 seconds) without more information. A key factor there would be the number of documents in the result set.Hopefully this is helpful!Best,\nChris",

In a lot of $match, there is no schema related to the $match-ed documents. In a pipeline, documents are altered or even generated (by $group). It would take a lot of complicated code to determine which schema to use, if any, to do type conversion. And it will be very confusing. For 1 $match you have conversion because we have a schema and for another one there is none because it is generated document.My conclusion is1 - type conversion occurs (may be not in your case) when documents are inserted because of the schemaPersonally, a warning or error would be better.2 - type conversion occurs in simple queries where it is clear which schema is usedIt makes sense because conversion occurs at insertion.3 - type conversion does not occurs in pipeline for $match because it would be hard to do and it will be very confusion because it cannot be done on some of the $match4 - storing numbers as string is a bad ideaA string with a couple of digits will take more space than the number and it is slower to compare. Numbers as strings are not in the natural sort order “2” > “111” but 2 < 111.5 - I am sure about the following.Personally, I experienced lots of trouble due to this behavior.Hopefully, mongoose has a way for you to communicate and ease your frustration.",

If I am able to get the time zone of the system, I do not need to worry about storing the offset and I can use the time zone to get my “local system time” (non UTC).This is especially useful in multi time zone system which also has to deal with Day light savings. For example, if we need to write a query “Get me all documents which were updated on a day between this time and this time”, there the time will be given to me as “local time”, unless I know the offset or time zone, I cannot get data by just using UTC.Hope this clarifies the use case.",

The Realm docs don’t mention limit/skip at all.The only docs I could find on skip/find in JS explicitly state:The order in which you call limit and sort does not matterThis is definitely not true in Realm Functions (although I’m not sure if these docs apply, which is confusing as this is MongoDB running in Node, but the find() API is a little different with projections in Realm vs. args in Node).Concrete suggestions:Whew!

However, during the process, I keep getting error about string formatting during JSON parsing. I looked into it and found that the body text that I got inside the ALtas function with payload.body.text() has been truncated to around 760 characters. When I log also, the request data, I can see that the full body (over 4000 characters) is there, just that somehow it was truncated when the data is accessed in the ALtas function. I searched over all documentation and forums but there is no mention of this problem. Just wonder if there is any hard limit to the length of the payload bodyReplication of this problem can be done via creating a https endpoint with a altas function, then send over a POST request with a large Body (over 3000 characters).Would be great if someone has experience using HTTPs endpoint with large payload can share your method",

But it only works once, so I hit play, it works, then it fails. Once I have any code changes that trigger a recompile, it works.Quick repro video of what this feels like:It hangs on the await in the last statement of the code snippet above.This is caused by Unity not reloading the .NET Domain, which is an advanced option that can be disabled in Project Settings->Editor->Enter Play Mode Settings. Recompiles always trigger domain reloads, which is why that alleviates the problem temporarily. This setting is used a lot by devs around the world because it seriously speeds up iteration time as projects grow - normally, Unity reloads the Domain whenever the Play button is pressed, but that quickly takes 1, 2, or more seconds (especially in DOTS projects or mature production code bases). It does come with some caveats that require slightly cleaner coding practices.Usually, this sort of “run-once” behaviour is an indicator that some resources that live in a static context aren’t properly unloaded or closed. A acceptable fix would be to expose some functions that manually control the lifecycle of Realm’s runtime that does “nothing” on first run but will re-initialize all static fields and singletons with null, so they will be properly recreated as needed.",

When signing up/in I get a unique secret user identifier which is used to check the authorizated credential state, but not to get a fresh identity token.\nMy research showed the only way to get a non-expired identity token is performing the Sign-In-With-Apple authentication again, meaning the user is presented with the login UI once again every single day.But requiring this every day seems unreasonable, especially from the UX perspective:\nAn edge-case where a person is signing up at 3pm, the identity token added to the secure storage.

When an invalid ObjectId() is used, this error generally occurs. E.g.:From a quick initial glance, I can see you trim() the req.params.id value, is this to form it into an ObjectId()? I’m not sure where else the issue could occur as they are from the request itself. Perhaps you could print the values (specifically for ObjectId() fields) that are used when you receive this error and verify they are valid ObjectId()'sRegards,\nJason",

Would that be a bad idea on a field like this?Indexing fields used in queries always help. If you need that field, and that field is a frequent use-case, then yes index it. You may always remove the index later if you find it detrimental to your other use-cases.each being a 6-character long string (HTML color hex codes)Strings take more space and are slower to compare (a string a compared character per character while a number is compared in 1 operation). In your case I would keep the colours as a number. An hex code is a number after all.One smart technique I never thought before, presented in Atlas Search to return all the applicable filters for a given search query without specifying - #2 by Erik_Hatcher in a different context might be used here. You could, for example, have frequent colour schemes (the facet_attributes) represented by a single number, an _id in another collection.

Foreground index builds were fast and produced more efficient index data structures, but required blocking all read-write access to the parent database of the collection being indexed for the duration of the build. Background index builds were slower and had less efficient results, but allowed read-write access to the database and its collections during the build process.Starting in MongoDB 4.2, index builds obtain an exclusive lock on only the collection being indexed during the start and end of the build process to protect metadata changes. The rest of the build process uses the yielding behavior of background index builds to maximize read-write access to the collection during the build. 4.2 index builds still produce efficient index data structures despite the more permissive locking behavior.For more information, see Index Builds on Populated Collections.Regards,\nStennie",

I’ve been watching some of the vidos en the MongoDB youtube channel and now I have a few guideliness to go with, however, I’m having a seriously hard time thinking what is the “correct” or “most efficient” way of building my documents for a specific project.I have several little “books” (really tiny) with 100 tickets each and the books can have different prices per ticket. They all have a specic series and a correlative. for example, AA 10290 to AA 10390, exactly 100.I need to prepare the “service” and give away a plastic bag with several of those books for them to go and sell each ticket. It should like something like this:01 Huge JackmanBook | N tickets\nAA 1000 - 1100 | 100\nAA 1200 - 1300 | 100\nAA 1400 - 1500 | 100When they come back, they could have sold the entire first book with 100 tickets. and come back with half of another.AA 1000 - 1100 | sold out\nAA 1200 - 1250 | 50\nAA 1400 - 1500 | 100Next “service” I prepare I will use the half sold book:AA 1250 - 1300 | 50\nAA 1400 - 1500 | 100\nAA 1600 - 1700 | 100And the process repeats.This is where the problem arrises. How do I keep track of all those tickets? should I create a document with 2 arrays for each book like this:assign the object id to the service document (or should i embed the entire book document in the service document?) and when the employee returns update the arrays values from for_sale to sold?According to some videos i watched, i should embed everything that can be embedded into just one document. So it should look like this:Each ticket of each book is unique with serie+correlative, I can’t have a repeated book with serie “AA” and correlative 1000 in any other service.Thank you so very much for your guidance!",

(I’m really having a hard time getting outside the mindset of a sql relational db schema).I think I’m confusing you a bit by using the word “book”, I just really don’t know what they are called lol. It’s like a tiny ticket book used as a, kind of, receipt when someone takes the public transportation in my country. When someone gets on, they pay X depending the route distance’s fee, $0.25, $0.35, $0.45 … $1.50. Depending on that, they hand a single ticket with that cost from the ticketbook for that price/route. The person on shift can have several ticketbooks with the same price per ticket or have a mix of ticketbooks with different prices.I don’t think they need exact control over what number of ticket has been given (it leads me to believe the design should be like the second example you gave me), they just need the starting correlative and end correlative, so we will know that if the ticketbook starts with 1100 and comes back with 1125, it means the ticketbook has 75 tickets left. Ticket amount in each ticketbook is 100 fixed, never varies.I would assume that using your second schema example, for the second service I will create, when I enter the seriesStart: 1125 I will have to look for a service collection where 1125 is between (inclusive) seriesStart and seriesEnd, to automatically get the seriesEnd and the available quantity of 75.

"text": "My question is, when we use the count we are not fetching the documents, then why it takes so much time and how can we reduce it?The vast majority of the execution time estimated by the explain plan output (looking at the executionTimeMillisEstimate fields) is running the $lookup stages. While counting documents doesn’t return the documents, MongoDB does still have to access all of those documents to evaluate the $match or other filter stages. In that case, counting is not going to be significantly faster than returning all matching documents since most of the execution time is spent running the $lookup stages.You may be able to speed up your query by filtering the “joined” dataset as early as possible to reduce the execution time of the subsequent $lookup stages or by moving some of the “joined” documents into the \"bookings\" documents so you don’t have to run a $lookup at all.",

It is also very important to keep in mind the steady growing of new elements that get added to the server, so just making like a partition-1 for the first 30 elements, partition-2, partition-3 and so one will not work (or does it?).This is such a common theme I think there clearly has to be some kind of solution.

You just create the ArticleView and if successful you $inc the Article/views. $inc is already atomic so if 2 ArticleView are created at the same time, which is also atomic, the count in $inc twice. The issue with transaction in this case, I think, is that you have 2 transactions starting at the more or less the same time. Both transaction take a snapshot of Article. One of the transaction terminate correctly. But now the snapshot of Article of the 2nd transaction is stale as it has been updated by the first transaction.I thought I had nothing to write.

I tried renaming “Code” into “k” and “Value” into “v”, but unsuccessfully.Other information: I’m trying to get to my result without using $unwind, because my collection is already 2M documents large, and each document may contain up to 25 steps. It’s not a problem for MongoDB per se, but it is for PowerBI when I export data using the BI connector (very poor performance).Also, I’m trying to avoid using $unwind + $group, because Compass can’t deal with such an amount of data with $group, at least with an M30 cluster.Any idea how to reach the desired output given the constraints above?Bonus question: ideally, I also wish my output to contain a second object:Parameters may appear multiple times (up to one time per step), however I require to output them only once.For the same reason as stated above, I wish to avoid using an $unwind + $group (even though it would do the job) because the amount of data crashes CompassThank you very much for your help and happy new year everyone!",

Given that:Edits to this page will be updated in your application immediatelyI’m thinking that something is wrong. Hmm… Maybe …OK, here is more details – I hosted my web page at different places/sites, this is what I was hoping to control. However, my web page connect to app services directly via its javascript code. Does that mean that the connection is made from my IP to the app service (which then can explain why my above trials failed)? If so, then my question becomes, since I cannot list every single person’s IP in IP Access List, is there any better solution, like restrict by hosted sites / reference host etc?Or, thinking out of the box, can I apply rate control, since now it is every single person’s individual IP is concerned?",

The best way to do this, is to use google-auth-library which is provided directly from Google.I initially thought the problem lied in the library, but I setup a test server using node and express, and tested this verification step. There was no error, and I received the verified and decoded token. I setup the same exact function on MongoDB Realm, and received an error.Due to this, I’m wondering if Realm does not support some of google-auth-library packages.

I would recommend you to upgrade to the latest version 4.0 release which is 4.0.28 or to a supported version 4.2 or newer for major bug fixes and improvements.\nAlso, please note that, the minor upgrade (4.0.x) do not introduce any backward compatibility changes.I have a cluster on 2 shards and 1 config server,Config servers store essential metadata for a sharded cluster, including which shards own ranges of data for sharded collections. If something happens to their single config server their recovery path will likely be restoring the entire sharded cluster from a backup. For a production environment specifically, the recommendation would be to have multiple config servers to handle failures if any.Since it is possible that you’re seeing the effect of a fixed issue due to the version you’re using, upgrading the server to the latest supported version would be my first step. After the upgrade, if the issue persists, could you share the output for rs.status() and sh.status() from the primary members of the replica set and mongos respectively.Best Regards\nAasawari",

"text": "Hi,This question isn’t directly answerable as it depends on your overall concurrent workload and resources. If you are expecting changes in performance (for better or worse), I would start by trying to understand how your query is limited by current resources.For example:Have you profiled time spent in different areas of your application’s request lifecyle (eg database processing, network transfer, application processing, and frontend rendering)?Are there significant memory, storage, or network limitations affecting your database throughput?Typically performance improvements are going to involve tuning across all areas involved in the request lifecycle.If the most limiting factor happens to be available RAM for query processing, upgrading to a larger database cluster tier would likely help. If the main performance challenge is time spent converting results from BSON (returned by the server) to native objects in your programming language or rendering in the frontend, changing your cluster resources is unlikely to improve that significantly.There may also be some performance wins that would avoid scaling up database resources such as checking:Your common queries efficiently indexedYou are optimising the data model and results returned. For example, Reducing the Size of Large Documents.Hope that helps!Regards,\nStennie",
