Vladimir Ozerov commented on IGNITE-11524:
------------------------------------------
[~tledkov-gridgain], I meant only client part. This is true that we should not
send any additional close requests to the server. This point was to clear
collection of statements as they are not viable anymore, so no need to keep
inside {{Connection}}.
