"text": "Hello @Peter_B1 ,Time series data, which reflects measurements taken at regular time intervals, plays a critical role in a wide variety of use cases for a diverse range of industries and are recommended based on particular requirements. For example, a stock day trader constantly looking at feeds of stock prices over time and running algorithms to analyze trends to identify opportunities. They are looking at data over a time interval with hourly or daily ranges. Another example could be how a connected weather measurement device might obtain telemetry such as humidity levels and temperature change to forecast weather. Additionally, it could monitor air pollution to produce alerts or analysis before a crisis occurs. The gathered information can be looked at over a time range to calculate trends over time.While time-series collections in MongoDB provide many benefits for storing and querying time-series data, they may not be the best fit for all use cases. It is important to carefully consider your application requirements and use case before deciding whether to use a time-series collection or a traditional collection to store your data.For example would the number of documents that need to be stored have an impact on the decision to prefer time-series collections over regular collections?It could be a factor in deciding whether to use a time-series collection or not. For example, if your dataset is small, then the benefits of using a time-series collection may be less pronounced. Time-series collections are most effective when dealing with large volumes of time-series data, where the reduced storage and I/O requirements can have a significant impact on performance.I would recommend you go through below links to get a better understanding around Time series collection and it’s use-cases.Time series, IOT, time series analysis, time series data, time series dbMongoDB allows you to store and process time series data at scale.

If not, how can I export my whole database (data, tables & indexes) from my serverless instance and then import it into my shared cluster?Currently, Atlas does not support live migrating from Serverless instances to Shared/Dedicated Clusters at the moment, however, we expect to add this functionality in the future. Please refer to the documentation for further reference into the current Atlas Serverless limitations.Also, if the serverless instance runs on a rapid-release version of MongoDB, you can’t migrate to a shared cluster. To learn more, please refer to the Operational Considerations.In the interim, the easiest way would be to restore your Serverless instance to a Shared/Dedicated Cluster. Please follow the procedure below:Create a new Dedicated cluster by following our Guide.Note: Please make sure you select the MongoDB version of your dedicated cluster as Latest Rapid Release which would deploy in the same version as the Serverless instance.Once the new cluster is created it will appear in the ‘Target cluster dropdown’ and you can restore the two most recent snapshots from your Serverless instance to the Dedicated cluster by choosing from the Target cluster dropdown.You can also use the MongoDB tools available such as mongodump/mongorestore to migrate the data from Serverless to Shared/Dedicated Cluster, which would include downtime.Here you can use the MongoDB tool mongodump to create a binary export of the data. With the binary export (mongodump file) you could create a new database or add data to an existing database with mongorestore.Meanwhile, you can also refer to the FAQ - Atlas Serverless Instances to learn more about the difference between serverless instances and shared/dedicated clusters.I hope this helps. Please let me know if you have any further questions.Regards,\nKushagra",

A wildcard index on productMetadata can support single-field queries on productMetadata, productMetadata.category, productMetadata.brand, and productMetadata.manufacturer:The index can support the following queries:In all of these queries, the index on productMetadata.$** would be used to speed up the query. The $** wildcard specifier matches all subfields of the productMetadata field, so the index can be used to satisfy any query that involves productMetadata.To learn more, please refer to this link:I hope it helps.

If I try a few different endpoints, they all time out, until after half a minute or so, it comes back to life and starts working again.For some reason I can’t see any traces of this in our telemetry so I haven’t been able to pinpoint the root cause of this behaviour, but once I pointed the staging environment back to our normal M10 cluster, I stopped seeing these timeouts.So I’m wondering, based on this loose description, if anyone knows whether or not Atlas Serverless clusters might be the cause of this?

"text": "Hello @Roland_Bole1 ,Welcome to The MongoDB Community Forums! It is advisable to use a sharded cluster instead of a single MongoDB server when your application requires high availability, scalability, and fault tolerance. Sharded clusters can provide you with the ability to distribute your data across multiple nodes, enabling you to handle larger volumes of data and higher numbers of concurrency.Some specific situations where a sharded cluster may be beneficial include:When considering a sharded cluster, it is important to consider your application’s specific needs and requirements. MongoDB provides guidance and best practices for designing, deploying, and operating sharded clusters, including recommendations for hardware configurations, network settings, and security settings. It is recommended to consult the official MongoDB documentation and seek advice from experienced MongoDB developers before setting up a sharded cluster. You can contact us at MongoDB Get-in-touch.For more details regarding Sharding, I would recommend you to visit below linkRegards,\nTarun",

ObjectId is a 12-byte identifier consisting of a timestamp, random value, and counter. In some implementations, the random value is a hash of the machine name and process ID (PID).In EJSON, the ObjectId is represented as, which is what Compass displays:When you parse and insert this ObjectId into MongoDB, it gets inserted as an ObjectId with value 64270173d513a771d2e3b5a2. When it is read back into the C# application, it will be deserialized as an ObjectId. No surprises so far. And you in fact see exactly this value in _id from your .NET Framework v4.0.30319 application:But when you attempt the same from your .NET Core application, you see:Two points to note…First the _id is now id, which is odd and unexpected. Given that you are working with BsonDocument objetcs, the driver would not be modifying the mapping of the BSON to change field names.Second the “GARBAGE” is actually the properties that make up the ObjectId. The ObjectId.ToString() implementation displays ObjectId(\"64270173d513a771d2e3b5a2\"). But that ObjectId corresponds to a Timestamp of 1680277875, Machine of 13964199, etc. The discrepancy might be as simple as whether your debugger is configured to display an object’s properties or its ToString() representation.Hopefully that helps. If you continue to see discrepancies between the output from different versions of the driver, please provide a self-contained, runnable repro demonstrating the problem including the .NET version, .NET/C# Driver version, operating system, and any other relevant data so that we can investigate further.Sincerely,\nJames",

"text": "Hi @Hassan_Edelbi,Welcome to the MongoDB Community forums MongoDB has a built-in feature called “Field-Level Redaction” that can be used to restrict access to certain fields within a document. It uses the $redact pipeline operator to restrict the contents of the documents based on information stored in the documents themselves. This feature will be particularly useful in your case if you need to hide the “fees” field from users who only have a “teacher” role.If you are creating a user at the database level, you can utilize the built-in roles. However, for application-level users, I’ll recommend using middleware in your application code. In your application code, you can define the roles and their corresponding permissions, and then use middleware to verify if the user making the request has the required permissions before allowing the request to proceed.Sharing the code snippet for your reference using Express.js middleware:Please note that this is for the above sample document created, however, this might change as per your document. Also, I would suggest having thorough testing before using it in production.I hope it helps!Best,\nKushagra",

Initially I thought I needed some many to many but as I got more familiar with the querying I decided it wasn’t necessary.My first pass was with 1 database and 20 collections (documents). I found this very easy to work with, querys were pretty straight forward, editing/updating of data went smoothly as did creation of new document elements. Only document deletion was more than trivial. My biggest problem was seeding the database. The project requires a database with 30,000 ish collections which have default data, the user then goes forward with a process in which the user gathers data and inserts into the database. On completion the entire database is downloaded with the default data replaced by current data. With this design 12 of the collections must be loaded with the 30000 default items before the remaining 8 can be loaded with the related objectIDs for the one to many relationships. At least that was my experience. This appeared to be a monumental task so I put that on hold and moved to a second approach.My second pass was to structure a database with one collection. I embedded some misc data and then nested the remaining. Actually pretty much like your Second. The database seeding then became very straight forward, I just created a JSON file with the desired nesting and used mongoimport to load my database. I am in the process of redesigning my app around this new database structure and have gotten to the stage where queries are pretty straight forward but I haven’t developed much beyond fetching the data. I haven’t yet got a clear picture of how to interface with the user to gather data.I work alone and would love to have someone to kibitz with, interested?Jim Rublee",

It’s working perfectly fine for the most part, however, for one of our collections we are getting the following error:(DuplicateKey) cannot write document with duplicate key: “countryIso” to parquet file: cannot create BSONSchema from document with duplicate keys: countryIsoThe documents in that collection contains a “deliveryAddress” field which contains an array of embedded documents, each containing fields such as “countryIso”, “city”, and so on. Is this what’s causing it? I’m fairly sure that I read that embedded documents should be supported. If not, how do we get around this?Thanks in advance,\nTom",

You can visit the documentation on data modelling for detailed understanding.To help you better with the appropriate solution, can you please share the below details:Is it possible to create Rule Expressions taking into account data from an additional table?Regards\nAasawari",

"text": "Hi @Ahsan,Welcome to the MongoDB Community forums Based on your shared sample documents and the update condition I’ve written an update query. Sharing the code snippet for your reference:The code uses the findOneAndUpdate method to update/insert a document in the user collection based on the email and date of the analytics. If a document exists, the analytics object is updated with new data using the $set operator and the arrayFilters option. If no document exists, a new document is inserted with the $push operator and the upsert option set to true.Please note this is just an example solution code and you should update this as per your requirements. It is recommended to evaluate the performance and test this with expected workloads based on your specific use case.I hope it helps!Best,\nKushagra",

The issue is the lab was opening ‘Project 0’ instead of MDB_EDU.I followed the instructions to the letter even creating another new account and setting up sample data in the new account (when this was already done in the very first class, then into the wrong project then finally into the correct project. Given how long it takes to insert this data it’s a pretty huge waste of time). Overlooking the project dropdown (no actual instruction as to what projects are as well) was poorly articulated in the lab and I must say I am thus far really frustrated with the classes.Here’s hoping it gets better as it goes along.",
