Ravi Kapoor created CALCITE-3784: ------------------------------------ Summary: RexCall toString digest gives OOM while huge expression is evaluated Key: CALCITE-3784 URL: https://issues.apache.org/jira/browse/CALCITE-3784 Project: Calcite Issue Type: Bug Components: core Reporter: Ravi Kapoor
I have some complex query which has tens of thousands of rex expressions and this expression is used in filter expression in the query. On creating a filter below code gets called: public RelBuilder filter(Iterable<CorrelationId> variablesSet, Iterable<? extends RexNode> predicates) { final RexNode simplifiedPredicates = simplifier.simplifyFilterPredicates(predicates); if (simplifiedPredicates == null) { return empty(); } RexSimplify further adds the rexnode in the Set<RexNode> calling hashcode() internally which calls toString() Is there any way to avoid this computeDigest Call which creates complex string object and blows up the RAM about 14GB? -- This message was sent by Atlassian Jira (v8.3.4#803005)
