------------------------------
Summary: Use ZK 3.4 API 'multi' in bulk assignment
Key: HBASE-6058
URL: https://issues.apache.org/jira/browse/HBASE-6058
Project: HBase
Issue Type: Improvement
Components: master, zookeeper
Affects Versions: 0.96.0
Reporter: nkeywal
Assignee: nkeywal
Priority: Minor
We use async API today. This is already much much faster than the sync API.
Still, it makes sense to use the 'multi' function: this will decrease the
network & zookeeper load at startup/rolling restart.
On a 500 nodes cluster, we see 3 that 3 seconds are spent on updating ZK per
bulk assignment. This should cut it in half (+ the benefits on the network/zk
load).
