Michael Han reassigned ZOOKEEPER-3437: -------------------------------------- Assignee: Jie Huang > Improve sync throttling on a learner master > ------------------------------------------- > > Key: ZOOKEEPER-3437 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3437 > Project: ZooKeeper > Issue Type: Improvement > Components: quorum > Affects Versions: 3.6.0 > Reporter: Jie Huang > Assignee: Jie Huang > Priority: Minor > Labels: pull-request-available > Fix For: 3.6.0 > > Time Spent: 2h 20m > Remaining Estimate: 0h > > As described in ZOOKEEPER-1928, a leader can become overloaded if it sends > too many snapshots concurrently during sync time. Sending too many diffs at > the same time can also cause the overloading issue. > In this JIRA, we will: > # add diff sync throttling in addition to snap sync throttling > # extend the protection to followers that serve observers > # improve the counting of concurrent snap syncs/diff syncs to avoid double > counting or missing counting -- This message was sent by Atlassian JIRA (v7.6.3#76005)
