------------------------------------
Summary: Reduce state messages when there are leader only shards
Key: SOLR-10285
URL: https://issues.apache.org/jira/browse/SOLR-10285
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Varun Thacker
For shards which have 1 replica ( leader ) we know it doesn't need to recover
from anyone. We should short-circuit the recovery process in this case.
The motivation for this being that we will generate less state events and be
able to mark these replicas as active again without it needing to go into
'recovering' state.
We already short circuit when you set {{-Dsolrcloud.skip.autorecovery=true}}
but that sys prop was meant for tests only. Extending this to make sure the
code short-circuits when the core knows its the only replica in the shard is
the motivation of the Jira.
