Just to provide some background on the work I am kind of building here, it uses under the hood the paper that You and Liu published on medium along with the notebook. Essentially, what I am trying to come around here is the deployment phase on streamlit of the vector_response based on the query/question. I’ve planned a dedicated section where we solely upload each/multiple files directly to MongoDB without any execution, after that, we can route our queries at each specific dedicated MONGODB_DATABASE on the persisted documents stored at each database within the cluster. I think of in that way (I am not familiar with the gears under the speed process of the index) we could direct each query to the specific database and take less effort and more speed response to the client. Two calls here, 1. to upload files related to the nature of each database and 2. route the query to the specific database and force the vector_response to be bounded in indexing only on the docs stored under that specific database (not sure if it is possible though).The problem I am facing is talking with the database directly from MongoDB using host, port, collections, and like. Appreciate if you could indicate the best way to share the line code to get further support from your side whenever possible. I am really stuck here.\n\nScreenshot from 2023-07-13 11-47-401438×681 49.2 KB\n",

While bad things can, and do, happen, it’s rare in my experience for two of the three nodes in a replica set to go down at the same time. Your time is better spent trying to bring the downed nodes back online. If you can get just one of them up and running you have a majority again and one will be promoted to PRIMARY status.Forcing your three node replica set back down to a single node replica set is very dangerous, especially in a production environment as you’ve lost any sort of HA.

"text": "Hi @Ebrahim_Karjatwala and welcome to MongoDB community forums!!Firstly, thank you for sharing all the information in detail.\nIn order to make the most accurate recommendation for the data modelling of the shared ER diagram, it would be greatly beneficial if you could provide additional information regarding the following:The are modelled in the following simple manner:Instead of adding reference to other entity, MongoDB gives you the leverage of using Embedding in MongoDB which would definitely help in efficient query processing.\nReferencing is however, one another way to create the relationships but in order to build it between the collections, but you might end up creating expensive operations like $lookup which in turn might end up being a slow query.MongoDB’s flexible data modelling allows us to design the database schema to optimise query execution time and efficiency, based on the specific use case. By carefully considering the data model, we can structure your data for efficient querying and performance.\nTo ensure the best performance, you can leverage MongoDB’s data modelling capabilities and discuss your use case requirements. This way, we can design a schema that aligns with your application’s needs and maximises query execution efficiency.This would make the query you wish to have more easier to fetch the data from the collections.This is the solution that I have come up with and it is working but I am not sure if this is the best possible way to model it.This could be one solution but this way your design might completely follow a relational approach and you might miss on feature and flexibility that MongoDB provides.However, in saying so, the data modelling always depends on the way the query has to be executed in the application.This is the solution that I have come up with and it is working but I am not sure if this is the best possible way to model it.Suggesting the best possible solution would be difficult without knowing how you’re expecting the data to grow over time.\nAs I mentioned earlier, if the collection is expected to grow significantly, you might need to evaluate the performance impact of your current approach as $lookup may become expensive in such conditions.For more assistance, you can also reach out to the MongoDB consulting who can guide you with the appropriate designs and implementation methods which would be best suited according to your use case.I would also recommend you to follow our MongoDB Courses and Trainings | MongoDB University for further understanding and learnings.Do reach out to us if you have any further queries.Regards\nAasawari",

However, it is not possible to configure this change because “MongoDB Atlas” is a cloud database service managed by MongoDB. By default, in the free shared tier it spins up a 3 replica set member (PSS) that provides redundancy and high availability.If you are looking to run a single-node replica, you can do so either locally or on-premises.May I ask why you want to convert it to a single node? Can you help me understand your use case?Looking forward to hearing from you.Regards,\nKushagra",

I have enabled diagnostic on some of our dbs, but from other posts on this forum/the doc, what the diagnostic/performance advisor/profiler show will be only slow queries, which is not the same thing as poorly targeting queries.For instance, the query I got the alert for still executed in under 30ms, so it never appeared on the profiler.What tools are there to identify queries (or at least the collections) that have a poor targeting performance ?",

As you mentioned, relying solely on a slowms threshold does not holistically capture inefficient operations, especially queries with poor query targeting performance that may still be completing within the slowms threshold.We are actively working on a project this quarter that will update how we profiler operations for Atlas Query Profiler/Performance Advisor. In an upcoming Atlas release, we will be updating Query Profiler/Performance Advisor to also show operations where query targeting ratio exceeds 10k.In the meantime, however, you can manually set your profiling levels to filter on operations that exceed a query targeting value by adding something like this to your profiler settings. Note, however, that you will need to disable the managed slowms so that your filter is not overwritten. Also, please consider any rate limiting that could occur on Query Profiler due to too many logged operations if you set the query targeting filter too low. The Query Profiler currently has a limit of ingesting 86400 slow query log lines per 24 hours per host.{$gte: [{$divide: [\\\"$docsExamined\\\", \\\"$nreturned\\\"]}, 10000]}Thanks!\nFrank",

However, when I try to connect using my phone’s hotspot or any other Wi-Fi network, I encounter this error consistently.I recommend checking if there are any firewall or network restrictions on the Wi-Fi networks where the error occurs. However, it seems like the DNS issue, try using Google’s DNS 8.8.8.8 and 8.8.4.4. Please refer to the Public DNS for more details.Apart from this, please refer to this response and try using the connection string from the connection modal that includes all three hostnames instead of the SRV record.If it returns a different error, please share that error message here.In addition to the above, I would recommend also checking out the Atlas Troubleshoot Connection Issues documentation.Regards,\nKushagra",

We have a table chart enhancement on our product roadmap, so if there is any idea/feedback, please feel free to submit in our feedback engine hereHowever to work around it, there are two ways you can achieve this.\nOption 1: use the query bar in the chart builder which you can run a custom aggregation for this particular chart to convert the date to string and display empty string for null values:Option 2: Given that you are already using the Charts view, you can also add above pipeline segment into your view aggregation pipeline.When creating the chart, use the newFields created with string type to display in the table.The difference between above options is that option 1 will apply to a given chart and option 2 will apply to the entire view.The caveat of using the workaround is that you will lose the date type in which means if you want to use dashboard filter with one of those field, it will be presented with a string filter rather than a date filter. If the table is just for displaying all the record, above workaround should achieve what you need.Another way I can think of is to assign null value with an early date e.g. 01 January, 1970 00:00:00, and use conditional formatting to make date earlier than x to display with white text color (we don’t support transparent text color). The issue with this approach is that as you hover onto the row, the text will be visible and it also will show up in dark theme if you are embedding the chart/dashboard, though it does preserve the date type.",

If you do need to run some async code (e.g. to wait for notifications or synchronization), you will need to install a context - for example, by using Nito.AsyncEx.In terms of using Realm for server-side rendering, it has both benefits and drawbacks. One benefit is that it optimizes transfer of data from Atlas and caches that data locally. This means if you get a lot of client requests for the same objects, you’ll be able to respond much faster than if you had to query MongoDB every time. There are two downsides to consider though:",

My guess is that you still want to roll out your own authentication mechanism - e.g. when a client logs in, you relay their credentials to Atlas App Services and obtain a user. Then, you issue an access and refresh tokens signed with your own keys and send those to the client device. When a client device makes a request, you find the user in app.AllUsers and then pass that user to the FlexibleSyncConfiguration.Now the challenge comes when we introduce load balancing. Then a client would not be guaranteed to reach the same web server on every request, meaning a user that logged in on server A would not be available in app.AllUsers on server B. There are two approaches for this:Note that the current SDK API are not a great fit for this use case, but we’d be happy to make small adjustments to support it. Notably, right now, app.AllUsers returns an array, which would be expensive if you have thousands of users.

I suppose it can share a place in the MEAN or MERN stacks, but in what situations would the WebSDK excel over just typical Atlas work?I want to be clear, this is not a “Use Realm as a Piñata” question, I’m actually being sincere and literal. As I’ve used the WebSDK in a 3D Website to count bubbles being popped by a user, etc. But it doesn’t have the ability to sync so it has to send the data to Atlas in batches, but also that’s how Mongoose does things too. Or Atlas functions unless you build a listener function and use triggers.I’m legitimately trying to find use cases where the WebSDK goes above and beyond, or really stands out from other traditional web development services that everyone else learns to do.As this question again was posed by someone else, and me and oa lot of others are stumped on how to answer this.",

Moreover, your URL seems correct and the error seems to come from the driver/application side.I would recommend you to upgrade your MongoJava-sync-driver v4.7.2 to MongoJava-sync-driver v 4.10.2 as there are a lot of bug fixes, improvements and new features available.Have you tried below recommended methods provided in the Timeout Error section of Java Sync Connection troubleshooting?Sometimes when you send messages through the driver to the server, the messages take a while to respond. When this happens, you might receive an error message similar to one of the following error messages:If you receive one of these errors, try the following methods to resolve the issue.The maxConnectionTimeoutMS option indicates the amount of time the Java driver waits for a connection before timing out. The default value is 10000. You can increase this value or set it to 0 if you want the driver to never timeout.Consider setting maxConnectionLifeTime and maxConnectionIdleTime. These parameters configure how long a connection can be maintained with a MongoDB instance. For more information about these parameters, see Connection Pool Settings.You might have too many open connections. The solution to this is described under Error Sending Message.If you are using an older version of Java, you might need to manually install some certificates as described under Error Sending Message.",

"text": "Hey @Gabriel_Pavao,Welcome to the MongoDB Community forums When should I create a new Collection?In MongoDB, collections are used to group related documents and provide an organized structure for storing data. It is recommended to create a new collection when there is a logical separation or when the data in the collection has a different structure or purpose. Doing so allows us to maintain data organization and improves query performance.When considering whether to create a new collection, think about the distinct characteristics or access patterns of the data. For example, if you have an e-commerce application that stores information about both products and customers. In this case, you might create separate collections for “products” and “customers” to maintain the different attributes and relationships associated with each entity.On the other hand, if a customer has multiple shipping addresses, you can choose to embed the shipping addresses as an array within the “customer” document. This avoids the need to create a separate “shipping addresses” collection.Also if you’re starting your MongoDB journey, I would recommend the following resources:These resources will provide you with valuable insights for designing effective MongoDB schemas.Best regards,\nKushagra",

What makes it a bit more complex is that the users have the flexibility to choose the different search filters / fields dynamically.To illustrate, here are two examples queries a user may request:Example 1db.songs.find( { genres: { $in: [rock, pop] } }, { moods: happy } )Example 2db.songs.find( { voice: female }, { moods: { $in: [happy, sad] } }, { bpm: { $gt: 90 } } )I’d like to optimize these queries using indexes, but given the dynamic nature of the queries, I am unsure about the best approach to create the necessary index or indexes.Is it a viable strategy to create a separate index for each searchable field?Alternatively, should I create a single index including all the searchable fields? I fear this may be problematic because I have several fields that are arrays (for instance, a song can be tagged with multiple moods / genres). As far as I know, MongoDB can accommodate only one multikey (array) index.

For that, I am not sure if the backend you and Nic designed using Main.js works. I think Karen’s strategy using webhooks would be easier via Realm. I know you guys want to address this in Season 2, but could you give like a short summary of what I would need to change to incorporate WebHooks instead of a backend?",

Webhooks can definitely replace the Node API we initially created. To do that, you’d create some Realm Functions and Webhooks that you’d interact with instead of calling a self-hosted backend (like we did with our main.js file.Check out this walkthrough of how to configure a service webhook in Realm.If you have any questions about the walkthrough, feel free to come back here and ask them and I’ll do my best to help you through them!",

In my case the service name is ‘mongdb-atlas’. While this linked datasource of my app has is pointing to the “cluster” instance, I created a new linked source that refers to the Federated Database Instance that, infact, is the environment where the external data source is linked.\nBy changing the service name everything worked.I appreaciated your help. Thanks a lot. ",
