             Summary: [hbase] Add a client config to limit write parallelism on the same key
                 Key: HDDS-11184
                 URL: https://issues.apache.org/jira/browse/HDDS-11184
             Project: Apache Ozone
          Issue Type: Sub-task
          Components: Ozone Client
            Reporter: Siyao Meng
            Assignee: Siyao Meng


Before HDDS-9844, {{{}write(){}}}s and {{{}hsync(){}}}s *on the same key* are always synchronized.

Now with HDDS-9844, {{{}write(){}}}s and {{{}hsync(){}}}s on the same key can now interleave, with only the critical sections synchronized.

 

This Jira aims to add a client side config to limit the number of concurrent write operations (write/hsync/hflush) on each {{{}KeyOutputStream{}}}, so that it acts as a safety in order to fall back to original behavior (no parallelism) when some previously unknown race condition surfaces.
