query
Key: IGNITE-15550
URL: https://issues.apache.org/jira/browse/IGNITE-15550
Project: Ignite
Issue Type: Improvement
Reporter: Aleksey Plekhanov
Currently, queries like:
{noformat}
SELECT MAP(SELECT 'a', 1)
SELECT ARRAY(SELECT 1){noformat}
Can't be executed, since logical plan contains \{{Collect}} relational operator
and there is no rule and no physical operator to convert this logical operator.
