             Summary: ZK perfomance problem when multiple updates thread of leader trying to update term
                 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.
