--------------------------------
Summary: Pipeline leader writes to followers
Key: KUDU-2176
URL: https://issues.apache.org/jira/browse/KUDU-2176
Project: Kudu
Issue Type: Improvement
Components: consensus
Reporter: Mike Percy
We may improve write latency and throughput by allowing multiple messages to be
in-flight from a Raft leader to its followers. Secondarily, it may also help
with MTTR (for re-replication) because after tablet copy a node has to catch up
via normal streaming means.
Note that pipelining writes could exacerbate the RPC “stacking problem” that we
already have under certain conditions.
