What changed?

  • Matching server propagates partition counts in ephemeral data.
  • Matching server validates partition counts sent by client, and rejects if they are too far.

Why?

Next part of dynamic partitioning.

How did you test it?

  • built
  • run locally and tested manually
  • covered by existing tests
  • added new unit test(s)
  • added new functional test(s) - covered by future integration tests

Potential risks

No change in behavior at this point, partition scale info is always nil, so nothing will be rejected. The server will start sending grpc trailers though.
