> Key: IGNITE-23440
> URL: https://issues.apache.org/jira/browse/IGNITE-23440
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Reporter: Pavel Pereslegin
> Priority: Major
> Labels: ignite-3
>
> 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
