Summary: Sql. Kill Queries
Key: IGNITE-23429
URL: https://issues.apache.org/jira/browse/IGNITE-23429
Project: Ignite
Issue Type: Epic
Reporter: Konstantin Orlov
In a dynamic environment, users may occasionally execute queries that were not
intended, or where the query logic is faulty (e.g., missing WHERE clauses in an
update or delete statement, or incorrect joins causing Cartesian products). The
ability to cancel these queries reduces the impact of such mistakes by
preventing excessive data processing or modification.
Besides, long-running or resource-intensive queries can degrade overall system
performance, especially in environments where multiple users or applications
share resources. Query cancellation allows administrators or users to terminate
these queries before they fully execute, freeing up valuable resources such as
CPU, memory, and I/O for other important tasks, preventing the entire system
from crashing.
This epic consolidates the work for improving UX by providing an ability to
cancel long running processes (like queries, transactions, or compute jobs)
from both user-facing and management API's.
