      Summary: Reduce memory allocations under common scenarios

      2022-09-04: Updating target date to 2022-09-09

      Status update:

      • Memory pool for reads and writes in review.
      • Remaining tickets are not directly related and will be deferred.

      Rationale for delays:

      • Memory pool review took longer than expected.

      Risks:

      • No risks.

      2022-08-22: Updating target date to 2022-09-02

      Status update:

      • Prototyping streaming approach found minimal improvement.
      • Scope to refactor has been closed.
      • Working on pooling approach. Expected to have review this week.

      Rationale for delays:

      • Investigation of prototype took longer than expected.

      Risks:

      • No risk.

      2022-08-08: Setting target date to 2022-08-26

      Status update:

      • Fixed excess memory consumption from Zstd compression.
      • Working on a scope document to propose using io.Reader and io.Writer for readWireMessage and writeWireMessage. This is testing streaming an memory pooling with benchmarks.

      Rationale for delays:

      • No delays.

      Risks:

      • No risks.
