Summary: Calcite integration. Improve join predicate testing. Key: IGNITE-13136 URL: https://issues.apache.org/jira/browse/IGNITE-13136 Project: Ignite Issue Type: Improvement Components: sql Reporter: Roman Kondakov Currently we have to merge joining rows in order to test a join predicate: {code:java} Row row = handler.concat(left, rightMaterialized.get(rightIdx++)); if (!cond.test(row)) continue; {code} it results in unconditional building a joining row even if it will not be emitted to downstream further. To avoid extra GC pressure we need to test the join predicate before joining rows: {code:java} if (!cond.test(left, right)) continue; Row row = handler.concat(left, right); {code} -- This message was sent by Atlassian Jira (v8.3.4#803005)
