Add useless sort nodes removal. #697

Closed ienkovich closed 1 year ago

ienkovich commented 1 year ago

Some code in RelAlgExecutor doesn't expect a sort node to be an input of another sort node. To not care about such cases, I added a canonicalization pass to remove such dead sort nodes.

Resolves #695
