Profiling Query Compilation Time with GPORCA
GPORCA is Pivotal’s Query Optimizer for Greenplum Database and Apache HAWQ (incubating). In this post, we describe how users can profile query compilation with GPORCA. This will aid users in understanding which of GPORCA’s steps is the most resource intensive, and what transformations are being triggered. Based on this information, users can provide query hints to reduce or increase the search space, see where the time and memory is being spent, and learn how to influence its decision making.
