    Description

      Epic Summary

      Summary

      Drivers will automatically retry any read operation that has not yet received any results exactly once. 

      Motivation

      Alleviate application developer pain

      • Application developers want to design fault tolerant or highly available applications without having to implement retry logic in their application
      • Application developers currently have to write boilerplate retry logic for reads (but not for writes).
      • Much like for retryable writes, developers should not need to think about this type of retry logic.
      • Furthermore, application developers transitioning from traditional, non-distributed architectures and topologies sometimes have a hard time reasoning about transitional MongoDB states due to single node faults or sharding/replication state.
      • Automatically retrying reads will allow these developers to focus more on the business logic and less on the implementation details of MongoDB.

      Alleviate Atlas team pain.

      • The Atlas team should be able to perform unplanned maintenance without impacting end users or requiring developers to add logic to prevent these failures from being exposed to the user.
