> [hsync] Add a client config to limit write concurrency 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
> Priority: Major
>
> 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) allowed on each
> {{{}KeyOutputStream{}}}, so that it acts as a safety in order to fall back to
> the original client behavior (no write parallelism on the same key) when some
> previously unknown race condition surfaces.
