Evgeny Stanilovsky updated IGNITE-20673:
----------------------------------------
Description:
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}
