>                 Key: IGNITE-12369
>                 URL: https://issues.apache.org/jira/browse/IGNITE-12369
>             Project: Ignite
>          Issue Type: Bug
>          Components: sql
>            Reporter: Konstantin Orlov
>            Priority: Major
> Query cancellation support was introduced in IGNITE-5439. From this time server expects
that ALL request have id. It breaks compatibility with clients whose version prior to 2.8.0.
> Furthermore backport of this feature to 8.7 breaks compatibility newer build of server
with older build of client.
> See {{ClientListenerProcessor#makeFilters}}. New filter with overrided _onMessageReceived_ is
created here. It tries to read request id and if there is not enough data to read long value,
it crashes.
