  Hi sir, thank you for the video. Very useful. I have a quick question as I'm very new to MongoDB. According to your embedding approach example, user with access, what if one day we need to query only the access information regardless of the users eg. how many access are there currently ... ? Should we change it to a referencing approach and a user will have a reference to access's object id instead? Or we can still use embedding in that scenario?

• 
  @NeerajGarg2 ай бұрын

  Hi, thank you for sharing your feedback and query. There could be couple of options. You can aggregate the access information and put in some collection based on time etc. (if that is the use case). OR there could be another option based on the access pattern. You should list all the possible query access patterns on your data. Then you will be able to find out the appropriate approach of selecting embedding or referencing. Hope this helps. please don't hesitate to reach out if still in doubt.

  Hi, The aggregation pipeline in compass given an option to export it to various language constructs like node.js, python or shell. The given code can be embedded in your choice of query execution engine ( programming language or shell). db.collection.aggregate(pipeline, options) an example from mongodb docs: db.orders.aggregate( [ { $match: { status: "A" } }, { $group: { _id: "$cust_id", total: { $sum: "$amount" } } }, { $sort: { total: -1 } } ] ) The following links can also be looked at for more details. www.mongodb.com/docs/manual/core/aggregation-pipeline/ www.mongodb.com/docs/compass/current/create-agg-pipeline/ www.mongodb.com/docs/manual/core/aggregation-pipeline/#run-an-aggregation-pipeline Hope this helps you.

  sir, I have a doubt. I am new to backend development. My question is, whether this serverless mongodb plan will handle user volume of 2000 at a single time with the read/write operations from my mobile app as frontend.

• 
  @NeerajGarg3 ай бұрын

  Hi, thank you for sharing your query. Can you please help me understand more about your use case. What could be the potential maximum peak load at any time. Does the load (2000 users at a time) mentioned by you hold true for whole day or any specific time of the day. Is it true for all the days or it is for a certain time of the day/week/month/year. How have you arrived to a figure of 2000 users at a single time. Is this figure the maximum or you are expecting more load in near future or in the long term. Having explored all the above queries ( there could be many more based on your answers), I would recommend to do a proof of concept with serverless and then decide if your requirements are fulfilled by serverless (assuming you have complete insights around your workload, the size of collections and data, the shards, the indexes and the query performance). Please let me know if this helps you and feel free to post your queries. You may also like to explore the cost of serverless vs shared/dedicated servers www.mongodb.com/pricing Best wishes!!

  Great Explanation sir I have one question sir if I have around 27 gb of data in mongodb database and we have some huge collections which contains 80lacs data for all different projects and users are facing buffering issues, loading issues so is it good if we go with the replica set approach or we can create separate collection for different projects. Our server has configuration of 64 gb of RAM and 6cores. Please suggest some approach or solutions to resolve this issue.

  Thank you for your kind words. In order to help you, need more details as mentioned below: Have you considered using indexes. If not, please create the indexes on the slow collection. If these indexes have been created, try using explain to understand the query which is running slow. kzread.info/dash/bejne/apiYl5ShXbCdqJs.html kzread.info/dash/bejne/hpp-yaSbhMmXgrQ.html Have you considered sharding your collection. If not, please select the appropriate shard key and then observe for a certain timeframe. This should help as well. kzread.info/dash/bejne/rHt6wZmkgaWyoZc.html Check my videos on schema design best practices and see if there are any issues related to schema design. kzread.info/dash/bejne/jJmI2dqOZKaWZ9I.html kzread.info/dash/bejne/no542q-jeNfHf7w.html All the above points are so critical and can help you to get rid of performance issues. If these don't help, please feel free to share your concern again with more details like sample documents, kind of queries you have been running, indexes created, output of explain command. Hope this helps. Best wishes !!

  Hi, was wondering if it’s possible to create a docker-compose.yml file that could create dynamodb locally with a table and items in it. I am working on it and find that the container is unable to follow the AWS commands such as aws dynamodb create table inside the running container (throwing command not found error). Also tried using .sh file …. Still no luck.
