Jiajun Xie created CALCITE-5392: ----------------------------------- Summary: Support Snapshot in RelMdExpressionLineage Key: CALCITE-5392 URL: https://issues.apache.org/jira/browse/CALCITE-5392 Project: Calcite Issue Type: Improvement Components: core Reporter: Jiajun Xie Assignee: Jiajun Xie
For example: {code:java} select productid from products_temporal for system_time as of TIMESTAMP '2022-11-19 00:00:00' {code} The `productid` expression lineage is null because `RelMdExpressionLineage` does not implement the corresponding method. We can implement method that for SNAPSHOT like other RelNode. -- This message was sent by Atlassian Jira (v8.20.10#820010)
