Description

IGNITE-16004 introduces guaranteed row order for multi-row operations, like GetAll, InsertAll, DeleteAll. We can leverage this fact to optimize the thin client protocol:

• GetAll can return values without keys (keys are known on the client), and without size (it is the same as input collection size)
• InsertAll and DeleteAll can return a bit set to indicate which items were skipped.
