    Description

      We just checking in DISABLE_CODEGEN_ROWS_THRESHOLD to master with default value 50,000.

      The option uses the planner's estimates to determine whether to disable codegen for a query based on the maximum number of rows flowing through any part of the query plan.

      It is similar to EXEC_SINGLE_NODE_ROWS_THRESHOLD in behaviour except the threshold is per-node rows instead of total rows.
