| Description |
|
We should provide a way to do fine grained sharding. Today this is possible using the ShardingStrategy mechanism. The ShardingStrategy mechanism needs to be enhanced to cater to the scenario where data may need to be retrieved from multiple shards woven together and presented to the consumer as one response. |

This bug encompasses the migration of data from parent -> child and child -> parent, on child attach/detach events of prefix based shards. |
