> URL: https://issues.apache.org/jira/browse/IGNITE-20673
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Affects Versions: 3.0.0-beta1
> Reporter: Evgeny Stanilovsky
> Assignee: Konstantin Orlov
> Priority: Major
> Labels: ignite-3
>
> Independent or (other words) unrelated queries need to be executed in
> parallel.
> Multi statement request can partially or fully consist of unrelated queries,
> i.e. queries which execution is not depends of previous query execution.
> Simple example:
>
> {noformat}
> --- start multistatement ---
> CREATE TABLE t1
> CREATE TABLE t2
> SELECT * FROM t3
> --- end multistatement ---
> {noformat}
> more complex case:
> {noformat}
> --- start multistatement ---
> CREATE TABLE t1 | paralleled
> CREATE TABLE t2 | paralleled
> SELECT * FROM t2 | not paralleled, waiting for previous execution
> CREATE TABLE t3 | paralleled
> --- end multistatement ---
> {noformat}
