      Summary

      Currently drivers are querying an AWS link-local endpoint each time a connection handshake results in authentication. This may result in hitting a rate limit.  Drivers should cache fetched AWS credentials if the expiration time is known, and only re-fetch the credentials when they are about to expire.

      Motivation

      Who is the affected end user?

      Users authenticating with MONGODB-AWS using automatic credential lookup.

      How does this affect the end user?

      Hitting rate limits may result in temporary unavailability.

      How likely is it that this problem or use case will occur?

      Likely for EKS and ECS users with many simultaneous connections.

      If the problem does occur, what are the consequences and how severe are they?

      Authentication failures requiring backoff and retry attempts.

      Is this issue urgent?

      No

      Is this ticket required by a downstream team?

      No

      Is this ticket only for tests?

      No
