Adding support to batch ZK callback optionally by setting sys var asyâ¦
Supports batching of zk callbacks. Can be enabled optionally with a system
flag (asyncBatchModeEnabled=true).
In my test cluster with 1000 resources, I find the number of callbacks
processed from ZK reduces from 2.4k to 119. This speeds up the controller and
also reduces the load on ZK
