TSO Proxy: Simplify TSO Proxy implementation by using one forward stream for one gPRC stream #6572

binshi-bing · 2023-06-08T07:15:38Z

What problem does this PR solve?

Issue Number: Close #6549

What is changed and how does it work?

Simplify tso proxy implementation by using one forward stream for one grpc.ServerStream.
#6565 is a longer term solution for both follower batching and tso microservice. 
It's well implemented, but just need more time to bake, and we need a short term workable solution for now.

* Fixed bugs in tso service registry watching loop. (tikv#6346) ref tikv#6343 Fixed the following two bugs: 1. When re-watch a range, to continue from what left by the last watch, the revision is wresp.Header.Revision + 1 instead of wresp.Header.Revision, where wresp.Header.Revision is the revision indicated in the response of the last watch. Because of this bug, it was processing the same event endless as you can see from the log below. 2. In tso service watch loop in /Users/binshi/code/pingcap/my-pd/pkg/keyspace/tso_keyspace_group.go, If this is delete event, the json.Unmarshal(event.Kv.Value, s) will fail with the error "unexpected end of JSON input", so there is no way to get s.serviceAddr from the result of json.Unmarshal.
