In the future, the total number of documents in the collection will be more than 100 millions.Example Data:\n\nSCR-20230814-mpjf1161×619 55.8 KB\nAdding a full-text search feature with mongoose is quite easy. However, all I need is to add partial and/or fuzzy search functionality to my project. I know Atlas Search is perfectly suitable for that but I have no enough budget to create dedicated MongoDB server in Atlas since I’m an unemployed person. My country is currently struggling for economic survival. So I cannot pay more than $40/month for text searching feature… Instead, I will create cloud server thanks to VPS providers like Hetzner at lower price.What are the best and budget-friendly alternatives of Atlas Search?

You would actually need to specify this as a ‘pre_filter’ not a ‘filter’ in order for this to work.

The example below should make this more clear.I’d also recommend increasing the value of k to a larger number, and adding an additional post_filter_pipeline search_kwarg that limits the results to k. This will boost the accuracy of your results considerably.Your search kwargs with both of these changes should look like thisLet me know if you run into any other issues!",

We have about 1,5 billion of those entries. From which about 10% are really different. So the idea is to aggregate the different requests into one. In the example above instead of the 2 requests there would be one left.The genral way I did it is to create an Aggregation-Pipeline with the following steps:The problem is here the data array would be 1,5 million or more entries large. That is way to much for a single document. Is there a way to distribute the push to different documents so that the end result will be multiple documents each containig a data array with 100 entries?I tried slice, limit and bucket. All of these don’t seem to be applicable to my problem.\nlimit only cuts away instead of distributing the documents.\nSlice seems to do the same: i can decrease the number of elements but not distribute them.\nWith buckets I would need to give boundaries, to miraculously get a size of 100 per bucket, which would call for variable boundaries so not really applicable to this problem.There are some more steps e.g. for merging back into the collection but they are not relevant to my question.We are using an Atlas Mongo DB version 5.0.19",

You can add a separate field in your documents to support suggested flow, if needed.1.

Of course, the memory usage isn’t linear, for example for around 100 files, the memory spike is only up to 10-15GB for example. But since we are running in kubernetes/docker, the GC doesn’t seem to know the actual limit of memory where it needs to be called, ending with the pod being deleted due to memory pressure on the node in certain cases.I’m not sure if we’re doing something wrong, or if there’s a way to limit the memory usage for encrypting those somewhat large files.

Indeed, with $text operator you can query the documents from one collection and you can not use it within aggregation pipeline.To be able to perform text search in joined documents from other collections, you need to use Atlas Search, which provides $search stage just for this case. As per documentation, $search must be the very first stage of any pipeline. That means, that we can not use it before $lookup stage, but we can use it the $lookup’s pipeline.I will demonstrate how it works with the examples below.First, we create test data:Then, we can join group members and filter them by name with the $search stage.Output:Note, that in order $search stage worked, you need to define proper index on Atlas.

However, the I am getting different errors during the process and not able to connect to the replica set at all.After spending a lot of times searching through internet and trying various options, I finally decided to create a simple docker compose file to demonstrate my situation. This docker compose file is taken from one of the github samples I stumbled upon, which is very similar to other solutions I have seen as well, which creates 3 instances of mongodb, add them to a replica set name rs0 and then use mongo init to initialize the replicaset.Here is the complete docker compose file:After I run this, I get the following message:\nimage1208×121 5.46 KB\nWhen I open the mongoinit container logs, I get the following message:Then I tried to connect to the primary db from NoSQLBooster, got a connection successBut when I completed the connection, it’s showing this message: not primary and secondaryOK = falseI tried this connection string:but got the error as shown below:\n\nimage597×625 56.1 KB\nAny help to solve this issue will be appreciated.

Or would it need to much processor power? For me it seems a bit „strange“ to look everytime, every comment or rating! But i heard, that the mongodb is very fast to look up complete collections (even big ones) and only cost very low processor power. I am bit of a nooby.I am also thinking about using a hybrid-approach and to add the first 10 comments also in the related text document and add the average rating (and only update the last one every 3 hours). Is this necessary for 1000 or even 10k users?The next but small question is: I want to show the name author of the text, but with the ref-command of mongodb i am only having the user_id of author (So, then I would have to search all users and assign the particular user_id to the authorname or username, everytime i display a text). Would it make sense also to add the authorname to the textdocument and also only update it manually in the backend every 12 hours? Or i am overestimating the necessary processor power again?Thanks for your feedback and advices.",

The main driver for the notifications feature was displaying items in a collection view and updating the UI in response to data changes. Each cell in the collection view might be displaying arbitrary graph of references from the top level object (e.g. a listview showing schools might want to display the address or the first/last name of the dean), which is why early adopters of the database were asking for deep change tracking.Unfortunately, we don’t plan to change the default and as I said there are no immediate plans to add support for keypath filtering. If you’re using Atlas Device Sync and this feature is critical for going into production with your app, you should reach out to your account executive and provide them with timeframes for when you need it and more information about the use case.

Only you can determine the best performing indexes based on your query patterns. It simply depends on too many factors. For example, if for a given serialId you only have 1 published value, have published in the index is kind of useless for performance, but the size penalty will be so small that you might as well have it especially if you query on serialId equality and project on published. Not that documents need to be fetched if a queried,sorted or projected field is not in the index; so if you have really big documents you would want to avoid fetching.",

Note, this may you will have to distinguish documents that have been processed with your aggregation pipeline and what documents - not.

I wGiven your example dataset, running the following pipeline:Would produce the following results:As you can see, documents are grouped in batches, only batch numbers are missing.

DBRefs have limited server-side support, and have to be resolved using additional queries to return the referenced documents.Overall DBRefs are a legacy convention best avoided in modern applications using MongoDB.Regards,\nStennie",

But, you gonna need to play dirty .\nIf you look chosely at the example of how $search meta is used with facets, you can see, that some data, can be extracted. It just needs to become good boundary names for the buckets. A good name, in your case should:I think a good candidate for that name can be createdAt field (see my example dataset below), but stringified - `createdAtString.I will demonstrate the idea with examples below.Example dataset:Example aggregation pipeline that contains conditions close to your query:Output:As you can see, now we have metadata (total documents selected) and actual data (docuement’s createdAt) in form of bucket names. Then, will little efforts, we can get the result you want:Final output:Atlas Search Index configuration object I used:If you afraid that two documents in your collection can have exact same createdAt value, you can, for example, concatenate document id to that string, so the value would look like ‘2023-08-11T15:30:00.000Z__M1’. But, in this case, you will have to add additional stages to disassemble this string in order to work with dates.Again, it is a dirty solution, but it works with $searchMeta ",

Not tried what about quering of this array right now.I’m clear that I try to do relations in a document based database, but this is something I cannot change right now. Question is now, is there a better approach to model this, instead of keeping all users which have access in a long list. I also thought about to have some kind of relation collection, with userid and document id as compound key, and then working with aggregations if I want to ask for all documents where user XY has access to.It looks like a realtive “normal” problem, so I’m not sure why I found so little about it, maybe I’m searching jsut wrong.

"code": "",
"text": "Hi,me again. I’m currently not sure how to continue with my usecase, maybe I’m doing something totally wrong. The problem I have is the massive amount of data and the many-to-many relation with this.In my system I have a collection with items with 15 million documents and also round about 5k users. The worst case is that each user has access to each item.First I thought, I can add to each of the 15million item documents an array with the user ids who having access to this item. If I now wanted to find all items a given user has access to, I could do this with one query in the items collection. But having an array of hundreds or even thousand fields on each document takes an eternity to create or even to push or pull on these arrays.For sure an array for each user about the items he can access is also not recommended, because in the worst case the array contains 15 million entries.So next I tried, and also found as a solution for this problem, is that if I cannot reduce the problem from a many-to-many relation to a one-to-many relation I could go for a in-between table. Something which is normal on sql databases to have a relation table.Here the next problem, one collection is not big enough for my use case, because I easily will bypass the 2^32 limit of documents per collection if 2000 users having access to 1 million items, I’m close to the max.So I thought whats about having for each user his own access collection, but then I found out that this is not recommended and an anti-pattern. So on this point my question, how can I handle this with mongo. Sadly switching to an sql based database is no option.Nevertheless I tried it out and for my testcase it works, it created an access relation collection on my machine (notebook with mongo 4 running on docker) in roughly 6 minutes, which is ok. Because this task will happen not often in production and it shows the worst case to create 15million documents.The next point is how can I speed up quering on this large collection? Each document has only 2 ids the uder and the object id and both ids are together a compound index. If I now query for 10k items if a specific user has access, it takes around 30s. Might be related to my machine, but 30s is quite long, is there a way to reduce the time?I know that this is a realy tough problem and the given cirumstances (mongo version 4, mongo as db to handle raltions, many-to-many relations) are not optimal, but I just wanted to know if I mussed something here or if it is what it is right now?Thanks and best",

Also, the current index does not appear efficient for this specific query filter.Per the ESR rules, an index on {status: 1, DateTime: 1} may be more optimal given the query criteria.Could you confirm if you see a similar number of numYields when re-running the query? This will help determine if it is truly a RAM space issue.Please let us know if you need any clarification or have additional details to share.Regards,\nKushagra",

Each entity is unique: all of them have their own official legal name, registration number, and other unique identifiers. And yet, some of them can have parent-child relationship between each other from the point of view ownership: one company can be a shareholder in another one and thus considered as parent. Since all the companies are quite unique I don’t think that imbedding child companies as an array of documents into the document of parent company would be a good idea. It’s not kind of “product-review” or “author-publisher” relationship which you can find in a lot of documentations and examples on this topic.So, could you please share the best practices of handling such kind of relationships in MongoDB?Thanks in advance,\nMax",
