Maksim Timonin updated IGNITE-15365:
------------------------------------
Description:
Currently KILL SCAN just removes query iterator from node, but doesn't send
cancel cache query request to every node. It leads wasting memory on nodes and
exceptions like:
{code:java}
class org.apache.ignite.IgniteCheckedException: Received next page request
after iterator was removed. Consider increasing maximum number of stored
iterators (see CacheConfiguration.getMaxQueryIteratorsCount() configuration
property).
{code}
see
# QueryMXBeanImpl.CancelScan
# KillComandsSQLTest#testCancelScanQuery
example of test can be found in KillCommandsMXBeanTest
