Hi, is there any daily request or read limit for MongoDB Atlas database? Like, how many reads per day I can make?

Hello @Marco_Ivan ,

Welcome to The MongoDB Community Forums! :wave:

As per Atlas M0 (Free Cluster), M2, and M5 Limitations

M0 free clusters and M2/M5 shared clusters limit the number of read and write operations per second. The rate limits vary by cluster tier as follows:

  • M0: 100 operations per second
  • M2: 200 operations per second
  • M5: 500 operations per second

Atlas handles clusters that exceed the operations per second rate limit as follows:

  • Atlas throttles the network speed of the cluster.
  • Atlas triggers a one second cooldown period before resuming the cluster’s operations on a given connection. If the queue is greater than the operations per second limit, operations might wait for more than a second in the queue.
  • If the number of operations per second drops below the rate limit threshold, Atlas resumes processing of the queued operations on each connection before processing any new operations on that connection.

Please go through below Limitations documentation for additional details

Regards,
Tarun
