Hi Ajeet,

Are you talking about putting more data bytes(bulk data) into a single
zNode?

I hope you know that, the data size (or packet size) is controlled through
configuration property - Java system property: jute.maxbuffer
Reference: https://zookeeper.apache.org/doc/trunk/zookeeperAdmin.html

ZooKeeper will throw exception if the data size cross this value. Could you
check ZooKeeper server logs to see the chances of exceptions and due to
that the client requests are failing.

Thanks,
Rakesh
