Motivation: Network is limited, we need to reduce amount of transfers between nodes. One of problem: Session actor has no knowledge about key range distribution (data shard locations). Which means we have to transfer data between data shard and kqp executor to perform read or write. Workaround: Provide estimation about keyRange -> nodeId distribution to use session (which means executor and other kqp components) created on the same node where located corresponding data shard.
