Details

    Description

      Similar to IMPALA-7115, we should consider setting a default value for this option that will reject queries that are likely to be problematic because of scalability concerns. The aggregate thread count really depends on scalability, so kwho probably has the best idea of what a realistic limit is here after the KRPC changes.
