Pavel Pereslegin updated IGNITE-23440:
--------------------------------------
Description:
At the moment we have 3 types of cancelable "activities".
# SQL query
# Transaction
# Compute job
Any of these process can be cancelled (killed) using SQL KILL query.
We need to design and develop an internal handler (KillQueryHandler?) that will
add the ability for external components (TransactionManager, IgniteComputeImpl,
etc) to register as a cancellation listener.
Overall, the cancellation of any such "process" consists of the following steps:
* if the process is local - cancel it
* send a message to other cluster nodes to cancel the process
