-----------------------------------------
Summary: Sql. Extend SQL cursor with ability to check if first
page is ready
Key: IGNITE-20454
URL: https://issues.apache.org/jira/browse/IGNITE-20454
Project: Ignite
Issue Type: Improvement
Components: sql
Reporter: Konstantin Orlov
For multi statement queries, in order to advance to the next statement we have
to get sure that the first page of result for current statement is ready to be
served. This allows not to depend on a user and finish the script even if no
one consumes the results.
Definition of done: there is an API available from within {{SqlQueryProcessor}}
such that will allow to be notified about completion of prefetch
({{AsyncRootNode#prefetch}}).
