Currently i have 382k doc in my collection and it’s growing…\nMy main plan now is to display daily weather and some graph displaying weather of the same day for all past years. i’m using node.js and graphql with apollo server for api and react native for the app.To reduce the file size i grouped all hourly data in days. From 382k i’m down to 16k. But i’m still struggling on storing this data in an easy and efficient way so that i can make one query and get back a specific day of of each year without making al look query and also how to query dates properly.I’m not really looking into how to code this but more like general opinion or suggestions.\nI looked into finding similar problem/solution on the net but no luck so far.in the meantime thanks for all the helpKind RegardsM",

If your transaction use case requires updating documents across multiple shards, you will have to replace any arbiters with secondaries.I strongly recommend avoiding arbiters in production as they introduce significant operational challenges.

Therefore, I guess, it is ok to use a self-signed certificate.On my host pc for the mongodb, I managed to connect to the mongodb like this from python:I tested the connection and it worked fine.Next, I tried to connect to my mongodb from another pc (the “client”) inside the same private router network. This always gives me the following error, when trying to request data from the host:Apparently, the client cannot connect to the hosted mongo db in time. The remaining mongo conf settings that I use are:I tried different combinations of the IPs listed in bindip, including adding 0.0.0.0. Nothing prevents the error from occurring. There must be something I have done wrong.Usually, as stated above, I connect to the db via SSH port forwarding. So, on my client ubuntu machine, I start a terminal forwarding the host’s 27017 port to the client’s 8000 port:On the client, once the tunnel is up, I connect like this:This also now works with the tls option enabled, as in the python code above, but only when the SSH tunnel is up (of course). However, I think there is no point in using TLS via the SSH tunnel, because the speed of transfer will still be limited by the SSH tunnel, right? Therefore, I am trying to now connect directly without the SSH tunnel, which however gives the timeout error.Can you help me with this? Any ideas?Thank you!Best, JZ",

Projection can be useful to ensure a query is covered (for example, specifying _id:0 for a secondary index that does not include the _id field). However, the size of the covering index adds to your working set and documents that are frequently or recently accessed will also be in the working set (possibly leading to more memory usage than without the covering index).The general case of a query that is not covered (such as your example above). Projection will not reduce the size of the working set: the full document will be loaded in memory (uncompressed) in order to select the required fields. Large documents where you are frequently working with a small subset of data are typically a schema design anti-pattern.For more information on document size and working set impact, please see:One more projection caveat (and a common misstep) is using $project early in an aggregation pipeline as an attempted optimisation. The aggregation framework automatically does dependency analysis to determine which fields are needed for subsequent stages. Early projection is redundant and can lead to less optimal memory usage for pipeline execution.Regards,\nStennie",

If you have CPU to spare, compressing the output with --gzip can reduce the amount of I/O for writing the dump to disk. You can also reduce I/O contention by dumping to a separate disk from the one hosting your dbPath and pausing writes to your deployment while taking the mongodump.mongorestore has to recreate all data files and rebuild indexes, so available resources will again be a limiting factor. If your resources are not maxed out, you could try adjusting concurrency via --numParallelCollections=<int> (default is 4) and --numInsertionWorkersPerCollection=<int> (default is 1).If you are looking for a faster backup and restore approach, I suggest using filesystem snapshots or copying the underlying data files per Supported Backup Methods.

This is not recommended however as the instances will be fighting for the same resources and performance will suffer. The other problem with this is that if the machine dies, then you’ve lost access to your entire database.The answer to your second question is yes as well. You just need to make sure that the proper firewall rules are in place to allow connections between the instances. As you mention, network latency comes into play here. Best practice is to have your instances placed in different data centers/network routes so it’s less likely that all instances are impacted by an outage in one location.",

"text": "I have currently implemented this and it works. Here flowers is a List of Flower which is\na Realm.Object.SwiftUI (xCode14, beta 4) now provides an editable SwiftUI.List, making this more compact code possible:Attempting to do this with a RealmSwift.List gives the following error message:\n‘delete’ is unavailable: Delete is available only for collections conforming to RangeReplaceableCollection.RangeReplaceableCollection conformance requires an empty initializer and the\nfunc replaceSubrange(Range<Self.Index>, with: C) method. These are both implemented by RealmSwift.List.By declaring compliance to RangeReplaceableCollection in an extension to List I can get the code to\ncompile and run, unsurpisingly I get this error message.\n‘Cannot modify managed RLMArray outside of a write transaction.’If I then make a copy of replaceSubrange and for debugging purposes simplify it to the delete of a single Element\nof the list and try to wrap that operation in a write transation like this:I get this error message:\n‘Object is already managed by another Realm. Use create instead to copy it into this Realm.’If I check the realm objects of self and thawed it seems the thawing creates and new object with a different Realm.At this point I am stumped. Any suggestions?Also in other places of my app I have found that if I directly use $list.append or remove\nmethods, things work, but as soon as I deviate from this I tend to end up with different list objects and multiple\nrealms. I would greatly appreciate an advanced tutorial on this topic!I guess many developers would like to use the new cleaner approach to NavigationSplitView and List so it would\nbe good if you could get this to work.As a side comment I have implemented my app on two different branches one for CoreData and one for Realm.\nI very much prefer Realm with its bettter fit to Swift. However I found the topic of updating elements and\nappending / removing from lists so complicated that at one point I gave up work on the Realm branch.",

The gist of the problem is you’re instantiating a Realm Object, ViewModel, populating it with some data, returning that model and passing it to another view. That action throws the error.

"text": "Hi,\nThank you for your response. Passing the StateRealmObject from the app to the ContentView works OK. The error occurs deep in Realm when deleting a object from the List as described in my first post. The trace is below.It seems that SwiftUI’s editable List, sets its data object with same list (same objectId) after doing the delete operation (to trigger notification?). As far as I have been able to trace down in the Realm code, it seems Realm does not recognize that this set operation is setting the list that is already set. I think this is the cause for the error. Why it only occurs when the object is an ObservedObject and not a StateObject I have no idea, still learning ",

"text": "Hi Guys! I have a front end background but I’m new to the databases and back end.I like to be certain about the stuff that I work with and right now I need to structure my database and models in MongoDB.I did read a lot of MongoDB articles about data modeling and different patterns, but I can’t properly fit my application into one of them.Let’s say I have 4 collections:User → Artist\nItem → ProductI need to have a User collection with some user specific fields like name and avatar etc. Some Users can apply to become an Artist - Artist(a new collection) also has got some artist-specific fields like music genres and so on.\nArtist always has to be a User first, but a User doesn’t have to be an Artist.The other part of my app is about the Item and Product collections. An Item might have a title and description fields. An Item can become a Product and extends Item’s fields with Product ones like price for example.For now we have a reference between a User and an Artist and Item and Product, but obviously there will be more references regarding the app itself. A User can buy a Product and an Artist can create an Item.So that’s just a small part of the app - there will be more collections and references in the future.\nI can’t find a way to model the data I have right now and I’m a bit worried about my current approach.For now I see two possible solutions:My thoughts on both of those solutions:\nFirst solution forces me to use populate(I use mongoose) or aggregate to join the collections whenever I need the data from both collections - Item & Product and User & Artist which results in having two queries. This might not be the best solution in terms of a performance, but I’m not sure if that will be the case.\nSecond solution feels weird for me - why should I have an empty fields on a merged collection when I don’t need them? I believe this approach will be more optimised cause I need to do just one query instead of two, but I have to say that the first solution feels more ‘natural’ for me.Is any of those two solutions any good? Or should I find a different path? Should I be worried about joining the collections?Thanks in advance, I really appreciate any help!",

"text": "Hi @M0ngo_newbie, welcome to the community .\nFirst of all, thank you so much for describing your concern in detail.First solution forces me to use populate(I use mongoose) or aggregate to join the collections whenever I need the data from both collections - Item & Product and User & Artist which results in having two queries. This might not be the best solution in terms of a performanceThat’s correct, there is a performance overhead for joining two collections.As per our Data Modelling guide:Embedded data models allow applications to store related pieces of information in the same database record. As a result, applications may need to issue fewer queries and updates to complete common operations.The second solution suggested by you seems correct with a small modification as follows:\nSuppose your current User document looks something like this:Therefore, to accommodate Artist specific details in your User collection, your User document would have the following structure:Now if you would like to search for more Artists in your database, you can do so by using the following command:Also, the same would be applicable for the Items document, instead of having Items and Products together, you can simply combine them in a single Product collection.Having said that, schemas are generally dependent on the application use cases. So, take a look at our forever free M320: Data Modeling course, where you will:If you have any doubts, please feel free to reach out to us.Thanks and Regards.\nSourabh Bagrecha,\nMongoDB",

"text": "I’m thinking of using MongoDB for an application that requires normalized data because it needs to access most entities separately. So a lot of it transactions will involve multiple documents.I’d like to use change streams to monitor all transactions and decide whether data needs to be sent to another service. But if several documents are transacted as a unit, they need to be sent as a unit to maintain consistency.From the MongoDB documentation, it looks like you can open a change stream on the entire database, but change events seem to be triggered separately for each collection. So it looks like a multi-document transaction will trigger several events for different collection. But what I really want is an event for the entire transaction. Is that possible with MongoDB?If it isn’t, I guess I could make the application duplicate the contents of each transaction to a dedicated collection, and then open a change stream on that collection. But that’s a lot of overhead.",

Replica set members compare the version number and replica set name to determine if their configuration is stale, so you cannot force an older version number.Can you provide more details on your environment:Thanks,\nStennie",

Whenever a member learns of a configuration with a higher version and term , it installs the new configuration.Since the server only looks for larger numbers for updating the new configuration, it will not update the version to a lower number as that could cause issues.There are ways of rebuilding your replica set without losing your data. If not done properly this could result in loss of data, or a complete failure of your database system. You will want to test any potential process for resetting the replica set version thoroughly before running on a database that is storing data that you care about.It will be interesting to see the answers to the questions that Stennie asked above.",

The size of the data is one big factor (smaller amount of data, less to download) and the other major factor is how fast your network can download data.The slower your network, the longer it takes to download the snapshot and the more time we have to keep the download machinery up and running. I normally suggest our Atlas users to download one snapshot to get a better understanding of how long the download takes and then you can also see the download line item in your invoice after that to see the exact price for your snapshots (again this can vary even with the same amount of data due to network fluctuations).",

This is normal and designed to prevent set version collisions if you accidentally force re-configurations on both sides of a network partition and then the network partitioning ends.It looks like that there may be a missing check for a valid range of version value, but there must be something else going amiss if your starting config version is 2147480329. Can you provide some more context on this version number – was that the result of a previous forced increment (or repeated increments) or a manually provided value?As noted earlier, the use case for force reconfig is for recovery from catastrophic issues where a majority of your replica set members are unavailable.

That’s a lot of reconfiguration.There are ways to reset your replica set version without losing your data.

If you can provide me with more explanation about term/version correlation please.I think I can be able to update the config following something similar to this instruction (https://www.mongodb.com/docs/manual/tutorial/rename-unsharded-replica-set/) ?However, I’m reverting to another operator for sure.Regards",

Ive not done it that way, hut there are generally multiple ways to do the same thing. Again I would caution to be very careful when doing this and test thoroughly on a test system so you make sure you get the steps right.

You may also find the following blog post regarding tips for atlas connectivity useful.I would also ask if you can try connecting using mongosh or MongoDB Compass to see if the same error occurs. Please let me know the results of this.Please note, use of the +srv connection string modifier generally automatically sets the tls (or the equivalent ssl ) option to true for the connection. You can override this behavior by explicitly setting the tls (or the equivalent ssl ) option to false with tls=false (or ssl=false ) in the query string. More info on this here.Regards,\nJason Tran",
