-----------------------------------
Status: Patch Available (was: Open)
> In OM serialize the Ratis reply eagerly so the retry cache holds bytes, not
> the OMResponse tree
> -----------------------------------------------------------------------------------------------

> Key: HDDS-16407
> URL: https://issues.apache.org/jira/browse/HDDS-16407
> Project: Apache Ozone
> Issue Type: Improvement
> Components: OM
> Affects Versions: 2.2.1
> Reporter: Sergey Soldatov
> Assignee: Sergey Soldatov
> Priority: Major
> Labels: pull-request-available
>
> OMRatisHelper.convertResponseToMessage returned a lambda Message that
> captured the parsed OMResponse and serialized it on every getContent() call.
> Ratis keeps the reply Message of every applied write in its retry cache, on
> the leader and on every follower, for the retry cache timeout, and the cache
> has no size bound. So under a write burst each OM retained the whole parsed
> response tree (KeyInfo, locations, ACLs) per request for that long, and
> re-serialized it each time the content was read.
