      Description

      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).
