Yury Gerzhedovich updated IGNITE-17412:
---------------------------------------
Description:
Exchange of sql fragments is havy and complex operation due to include
serialize/deserialize operations and recreate execution context for fragment
For prepared statements we could avoid extra sending of wury fragments and have
separate cache SQL fragments on map nodes. As for example it could be some id
which will be generate during first send/execute of fragment and using for all
next execution for the same prepared statements. Let's try inroduce the
optimization and do some benchmarks to show performance increase.
