--------------------------------------------
Summary: Config option to throttle the number of recoveries
happening in parallel
Key: SOLR-12568
URL: https://issues.apache.org/jira/browse/SOLR-12568
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrCloud
Reporter: Tomás Fernández Löbbe
I've seen cases where a node that was out of service, once it reconnects, all
the replicas hosted in it will try to recover at the same time. In some cases
this can cause the host to run out of disk space (for reasons that can cause
replication to duplicate the index size, like a new leader, or simply segment
churn). I'm mostly thinking in throttling the number of parallel recoveries in
a node, but maybe it's also useful to throttle per collection/cluster for other
reasons
