Hi, in case of a rebalance, partitions are reassigned and thus (shards) of a store might move from one instance/thread to another. This could potentially happen anytime, and you need to rediscover the shard/store afterwards. Thus, your code must catch this exception and you can retry the query after store rediscovery.
