"text": "Hi, I recently started using CSFLE with enterprise edition. We are using the following AutoEncryptionSettings settings to create the client:Whenever our App restarts per server, we create a new data encryption key using “clientEncryption.createDataKey(“local”, new DataKeyOptions())” command as we didn’t want to use a single data encryption key(DEK). The output of the above createDataKey command is base64 encoded and pass to the schemaMap as “base64DataKeyId” as shown in above autoEncryptionSettings. Problem is, we inserted data into “school” collection using 3 App servers(that is, we currently created and used 3 DEKs in 3 servers to insert entries) and when we try to fetch all these records using a 4th server, we are getting the following exception:But everything works fine when we use a single DEK across all servers.\nSo, I would like to understand what could be the issue when using multiple DEKs or if it is recommended to use a single DEK.",

Possibly it will also be chosen over another index even if it results with worse performance eventually or over time (as plans get cached for queries).In your case I believe the database treated the type $in as a range operator while respecting your sorting fields which requireIf you will use an index that does not have those fields consecutively, it will not be able to use it for the sort. This is a heavy penalty to sort in memory compare to sort on index and I beilive this is the main incentive of choosing the index.I would say the best index for this query is actually:So we have the equality and sort bundled as first part then we go to any other equality/range fields.Again, to make sure that this index is the best one you can use a hint clause and run it to check if performance is indeed better. Otherwise, use the most performant index even if it is not exactly according to ESR…Thanks\nPavel",

"text": "Now I have added two more Fields in user collectionMongoDB uses flexible schema, meaning you can change fields freely. unless you need strict schema in your API as many frameworks need that. you need versioning if you change too many things.if those two fields (or any new field) are not mandatory inputs (meaning they can be null), then you don’t need any change in the production database. that is the flexibility of document databases.otherwise, you need to add a versioning field to your new schema (model) as well as a second schema to process old documents. this introduces extra (inescapable) work to your application as you have to work with 2 schemas every time you read a document. you should also start a migration logic about old documents because at some point you will have many versions to deal with any time you add a mandatory field.added and removed indexing on different collectionindex contents are based on the current documents in the database and changed with each insert/delete/update operation. so even if they use the same keys, production indexes are different than your development indexes because documents are different. to keep your customer’s data intact, you need to script your way for removing/adding indexes.",

This makes me think how would you specify a query that specify a field that does not exists.You probably could reverse your logic and have start with enrichmentstatus:null rather than non existing status and have your partial index expression to be enrichmentstatus:null.the requisite to create partial indexes with ‘$and’ operator at the top-levelexample:By top-level only, I could only assume that $and has to come first.

"text": "You may skip reading this post as a correct solution is in the next postLast minute note: You may read after COMPLEX AND WRONG SOLUTION BELOW but I found that I err and I could not producein the result set because I was going for a single PPV max per input documents. And it looks you want a PPV max per Row.Cell. This is simpler because a lot of $map can be removed from the solution below once you $unwind.I’ve been contemplating whether having an intermediate step like this would be beneficialI find it always beneficial. But I would start withto simply the data to:Some of the stages from the wrong solution below can be use but in a much simpler form. In most only the inner $map is required now that it is $unwind. The _set_indices stays the same. For example _set_PPV with the double $map becomesI will publish a real solution, after I sleep. Good Night.COMPLEX AND WRONG SOLUTION BELOWThe fact that some times HistogramDataIntervals is an object and at other times it is an array.My first stage would be a $set to unify everything to an array. Something like:Then another set stage which could be combine with the above but I like to separate them. This set just set fields to then index needed to get the ppv and freq values in different arrays.Divide and ConquerNext transformation would use $map on _Data to extract PPV values into a separate array using _ppv_indices for the Row.Cell embedded array. Something like:Doing the same as above but for Freq.My next transformation would be to user $map to convert the values of _Freq.freq and _PPV.ppv to numbers.Ditto for Freq.Now the data (_PPV_converted and _Freq_converted) is in a workable format to get the max ppv.Now that we know the max within which time row we can find the max of the document.The rest gonna be for another day. I am done for today. As a final note a lot of those $set can be done in a single stage. But when developing I find it easy to keep them separate. Optimization can come after accuracy.",

So essentially an update is a “transaction” of delete => insert new with same _id => insert old.If updates are so frequent and the critical path is the write and not the read you may consider the following alternative:Insert a new version into the main collection keeping the history in the same one (you may offload the history as a batch process)In this design I Invision the collection as follows:The index for lookup by id is now { itemId: 1, timestamp: -1}When you lookup by id you do:This will get only latest version.Thanks\nPavel",

"text": "For all services, if you have a cross-collection link then implicitly it is just storing a foreign key to the linking collection. This means that if you query collection 1, you will get all of the primary keys for collection 2 (the one being linked to). For sync, this means that if you query on a collection you will get all of the foreign keys but none of the actual objects that they refer to. The SDK’s will handle this under the hood by letting you know that the list is “empty” in this case and they treat links as null unless they actually have the object being linked to. Therefore, in order to effectively use links you need to query on both collections and have permissions to view both collections (which makes sense since you shouldn’t be able to bypass permissions just because you have a link to an object)This is why it is often a better fit to use embedded objects when there truly is a “has-a” or “has-many” relationship. However, it still is very possible to use relationships effectively with sync, you just need to have access to both collections.",

A few things here:I turned on development mode, and ran the client app to update the schemaYour local schema can actually be a subset of your server-side schema. So, removing the table from your local data model would not trigger the table to be removed from your server-side schema. Similarly when removing fields from a schema in your local data model. Development mode changes are additive-onlyError is the following: “cannot define relationship for field which does not exist in schema”This likely means that you still have a relationship that references the property you’re trying to remove. From the schemas tab, there’s should be a toggle labeled “Expand relationships”, if you turn that on you’ll be able to see the relationships defined on your table, and remove the ones that you no longer need. See https://www.mongodb.com/docs/atlas/app-services/schemas/relationships for additional details.It’s also worth noting that removing a property on a synced table is a destructive schema change, so you will be prompted to terminate + re-enable sync when trying to save this schema change.

"text": "Hello, @karthick_d . Thanks for your question.We definitely recommend using the mgocompat registries to mimic the encoding and decoding behavior of mgo (see docs here). If you’re trying to have nil, uninitialized Go slices Marshal to BSON empty arrays and not to BSON null, you should just use mgocompat.NewRegistryBuilder(). If you want the other features of the mgocompat registry, but you would like nil, uninitialized Go slices to Marshal to BSON null, you should use mgocompat.NewRespectNilValuesRegistryBuilder() (from your comment “nilvalues in the models as empty array”, this might not be your desired behavior).You’ll want to call SetRegistry a single time on the ClientOptions passed to Connect. SetRegistry will change the registry used internally when we Marshal and Unmarshal values to and from BSON. Calling it multiple times on the same ClientOptions struct will simply reset the value.Given the context of your code; I would suggest something like:I can see you’re trying to register a type map entry of EmbeddedDocument for bson.M. The mgcompat registries do that by default, so you shouldn’t need that logic.Also the other problem that i see is i’m not able to see the mongocompat registry file in my vendor directoryI believe the vendor directory will only contain the packages that are used in your application or the packages imported by those packages. You’re likely not referring to mgocompat anywhere in your code, so it’s not vendored.",

If so, this is possibly due to \"IN\" being a stop word and perhaps the below default_language specification on the text index may help your use case.Please also note that as per the Text Search Languages documentation:If you specify a language value of “none”, then the text search uses simple tokenization with no list of stop words and no stemming.Test documents, text index and initial $text query yielding no results:Dropping all indexes on the test collection, re-creating the \"text\" index with {default_language: \"none\"} and performing the same $text query above:Hope this helps.On a side note, if you’re running on Atlas then perhaps it may be worth taking a look into Atlas Search.Regards,\nJason",

Having a static domain name does not guarantee having a static IP. your cloud provider might be changing the IP address of the host where your app resides if you don’t have a static IP subscription. they are, after all, virtual PCs or containers and will most possibly be restarted with different IP addresses regularly (disaster recovery, load balancing, etc.). If you have set strict network access in your MongoDB server, then your app will have no chance but give a timeout.

Up to 1.000 searched values are expected for a single query.The documentation for $in says:It is recommended that you limit the number of parameters passed to the $in operator to tens of values.

Could you permanently tag documents with those values with a field that will tie them together so your query becomes a single value (the tag) search?If the search values come from another query, could you use aggregation with $lookup rather than retrieving 1000 values and the use the 1000 values in the findMany? About findMany, which driver has the method findMany() rather than find()?Querying 1000 values could result in 1000 documents and many more, what do you with so many documents?

"text": "Hi all,Is there any way to have the equivalent of multiple groups of logical OR in Atlas Search? I have a query case where a result must satisfy at least one condition of one group of criteria and at least one condition of another group of criteria. Having two “should” clauses would not work. Also it is very limiting that there cannot be a $match before the $search stage. One of the groups of OR requires that a document field is in an array of ObjectIds, but we cannot use $equals in Atlas Search as it accepts only one ObjectId, not an array.Many thanks for help.Kind regards,\nGueorgui",

"text": "Thank you Elle.A sample document looks like this:A user needs to be able to search for documents (books) that are in several shops by supplied array of shopIds (any of them should match) and also for books that fall in any one of the three categories (bestsellers, recommended - essentially 4 star or over rating, and new arrivals - essentially listed in the last 30 days) - the user may select one, two or all three categories and any should match (a book may be in all three). So both searches use logical OR. I can include a separate $match stage after $search, which seems the only option available given the constraints of Atlas Search. Is there any other way to do this in the $search stage?Many thanks.Kind regards,\nGueorgui",
