      Summary

      Client backpressure retries must not block the driver from performing other operations. The current test suite does not explicitly verify this, which risks implementations that behave incorrectly.
       

      Motivation

      Who is the affected end user?

      All users that experience overload with a backpressure-enabled driver.

      Who are the stakeholders?

      How does this affect the end user?

      Non-compliant drivers would block other operations during backpressure retries.

      Are they blocked? Are they annoyed? Are they confused?

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

      N/A.

      Main path? Edge case?

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

      A non-compliant driver implementation would negatively impact end users.

      Minor annoyance at a log message? Performance concern? Outage/unavailability? Failover can't complete?

      Is this issue urgent?

      It should be done before a driver's initial backpressure release to verify conformance with the spec.

      Does this ticket have a required timeline? What is it?

      Is this ticket required by a downstream team?

      No.

      Needed by e.g. Atlas, Shell, Compass?

      Is this ticket only for tests?

      Yes.

      Does this ticket have any functional impact, or is it just test improvements?

      Acceptance Criteria

      Test improvements only.

      What specific requirements must be met to consider the design phase complete?
