In some cases 0 may be the right estimate (e.g. for > streaming nodes like SelectNode that just pass through data) but we should > remove TODOs and document the reasoning in those cases. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
