-------------------------------------
Summary: [hsync] Unsynchronize hsync API
Key: HDDS-9844
URL: https://issues.apache.org/jira/browse/HDDS-9844
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Wei-Chiu Chuang
The current hysnc implementation KeyOutputStream.hsync() is wrapped in a
synchronized block. The HBase write ahead log FSHLog.SyncRunner has multiple
threads invoking hsync in parallel to reduce client latency.
We should unsynchronize Ozone's hsync such that it doesn't block waiting for
the Ratis transaction to respond.
cc: [~szetszwo] this is what we discussed offline.
