Propagate maxParallel hint to non-single threaded operators

    XMLWordPrintable

    Details

      Description

      Currently, the maxParallel query hint is only propagated to join nodes (see PipelineMaxParallelHint). We want this hint to apply to all operators that are not single-threaded by design (i.e., not an instance of the marker interface ISingleThreadedOp).

      This requires changes to (a) the query hint and (b) a review of how we propagate the query hint, we need some test cases (similiar to TestQueryHints by idea) to verify that the query hint comes through for the different operators. In particular, we also want the query hint to apply to the chunked materialization operator following the final project (cf. BLZG-1958).
