Subject [jira] [Created] (IGNITE-9182) Propagate lazy flag to synthetic SELECT used by first step of DELETE

------------------------------------------

             Summary: Propagate lazy flag to synthetic SELECT used by first step of DELETE
                 Key: IGNITE-9182
                 URL: https://issues.apache.org/jira/browse/IGNITE-9182
             Project: Ignite
          Issue Type: Bug
          Components: sql
            Reporter: Stanislav Lukyanov


When DELETE is executed it first executed SELECT with the same WHERE, and then deletes all
results via an invoke(). If a large number of entries is to be deleted, it may lead to OOM.

The task is to allow to perform the SELECT with the parent query's LAZY flag.
