---------------------------------
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.
