---------------------------------
Summary: A new collection property autoRebalanceLeaders
Key: SOLR-10780
URL: https://issues.apache.org/jira/browse/SOLR-10780
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrCloud
Reporter: Noble Paul
In solrcloud , the first replica to get started in a given shard becomes the
leader of that shard. This is a problem during cluster restarts. the first node
to get started have al leaders and that node ends up being very heavily loaded.
The solution we have today is to invoke a REBALANCELEADERS command explicitly
so that the system ends up with a uniform distribution of leaders across
nodes. This is a manual operation and we can make the system do it
automatically.
so each collection can have an {{autoRebalanceLeaders}} flag . If it is set to
true whenever a replica becomes {{ACTIVE}} in a shard , a {{REBALANCELEADER}}
is invoked for that collection
