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.
