------------------------------------------
Summary: Fix IO threading model
Key: IGNITE-20373
URL: https://issues.apache.org/jira/browse/IGNITE-20373
Project: Ignite
Issue Type: Improvement
Affects Versions: 3.0
Reporter: Alexey Scherbakov
Fix For: 3.0
Currently IO is resubmitted to inbound pool for further processing (even there
are corner cases then a message handler called in IO thread)
It introduces additional latency in message processing because each component
other uses it's own pools.
addMessageHandler should be extended with a 3-d argument: a pool for submitting
a callback for execution.
Some kind of message header can be passed along the way for precise pool
selection (similar to jraft IO model)
