Description
//Remove subquery LOG.debug("Plan before removing subquery:\n" + RelOptUtil.toString(calciteGenPlan)); calciteGenPlan = hepPlan(calciteGenPlan, false, mdProvider.getMetadataProvider(), null, new HiveSubQueryRemoveRule(conf)); LOG.debug("Plan just after removing subquery:\n" + RelOptUtil.toString(calciteGenPlan)); calciteGenPlan = HiveRelDecorrelator.decorrelateQuery(calciteGenPlan); LOG.debug("Plan after decorrelation:\n" + RelOptUtil.toString(calciteGenPlan));
The LOG.debug() consumes more CPU than the actual planner steps.
