Key: SOLR-12135
URL: https://issues.apache.org/jira/browse/SOLR-12135
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: 7.3
Reporter: Cao Manh Dat
Assignee: Cao Manh Dat
Fix For: 7.4
>From SOLR-12087: When multiple updates thread failed to send updates to a
>replica, all the threads will try to fetch latest shard term from ZK, lead to
>high load between leader and ZK. We should introduce a locking mechanism so
>only on fetch will be made in this case.
