> @lhotari I know. What I want to ask is when `ManagedCursor#asyncReadEntries` is called, the `OpReadEntry#getNumberOfEntriesToRead` will be called eventually even after your change. Is it called in another thread? If yes, there could still be a thread safety problem. The concurrency design doesn't currently ensure single thread access. It's possible that there is multi-thread access at the moment. For example, the scheduler uses a different executor and therefore also a different thread. However, I believe that this PR improves the existing solution and can help reduce issues caused by thread safety issues. I think it's possible to incrementally refactor the concurrency solution towards a solution where a single thread handles all accesses for a specific key (managed ledger name in this case). We can have a broader discussion about this on the mailing list or in some upcoming community meeting. -- This is an automated message from the Apache Git Service.
