--------------------------------
Summary: Evict replicas that are alive but lagging
Key: KUDU-1731
URL: https://issues.apache.org/jira/browse/KUDU-1731
Project: Kudu
Issue Type: Bug
Components: consensus
Reporter: Mike Percy
In the case that a replica is consistently behind the other replicas, we may be
able to detect that the node is slow and evict it. (Currently under high write
load we very often degrade to all tablets having just two live replicas and one
COPYING)
* In fact, this would also be useful for leaders that are significantly slower
than their followers.
* We should instead recruit a new replica and only evict the lagging one once
the new one is online.
