Subject Kafka Streams | Impact on rocksdb stores by Rebalancing
Date Tue, 09 Jan 2018 07:42:30 GMT

I would like to understand how does rebalance affect state stores
migration. If I have a cluster of 3 nodes, and 1 goes down, the partitions
for node3 gets assigned to node1 and node2, does the rocksdb on node1/node2
also starts updating its store from changelog topic.

If yes, then what impact would this migration process have on querying.

Also, if the state store restoration process takes time, how to make sure
another rebalance doesn''t happen.
