SOLR-17894: Support collection state.json compression when Overseer is
disabled. (#4905)
> state.json compression isn't happening with Overseer disabled
> -------------------------------------------------------------
>
> Key: SOLR-17894
> URL: https://issues.apache.org/jira/browse/SOLR-17894
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 9.0, 10.0
> Reporter: Paul McArthur
> Assignee: Andrzej Bialecki
> Priority: Major
> Labels: pull-request-available
> Fix For: main(11.0), 10.1
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> When running SolrCloud with the Overseer enabled, ZKStateWriter compresses
> state.json when it is written to ZooKeeper.
> This same compression does not happen when running in Solr Cloud's
> distributed mode, without an Overseer (DistributedClusterStateUpdater).
>
> In some cases, with very large collections, a cluster that runs with an
> Overseer can encounter problems when transitioning to distributed mode where
> updates to state.json persistently fail. This happens because the
> uncompressed size of the data is too large to fit in the configured jute
> buffer.
