yunfeng created CALCITE-3442: -------------------------------- Summary: Set `stored_fields = _none` prohibit `FetchPhase` get be involved and improve the Performance for Elasticsearch Key: CALCITE-3442 URL: https://issues.apache.org/jira/browse/CALCITE-3442 Project: Calcite Issue Type: Improvement Components: elasticsearch-adapter Reporter: yunfeng Fix For: next
For elasticsearch-adapte, when ElasticsearchAggregat involved , set _source = false and size = 0 , Elasticsearch `FetchPhase` would still be executed against the current search process and visit the Lucene stored_fields, which would lead to performance declined dramatically. We can set `stored_fields = _none` prohibit this such behavior completely -- This message was sent by Atlassian Jira (v8.3.4#803005)
