By "active" partitions I mean OK, after consulting with Alex I'm paring this wording way back. Just too many ways that someone could do extra work that was counterproductive or didn't have the benefit that they assumed. http://gerrit.cloudera.org:8080/#/c/7999/3/docs/topics/impala_partitioning.xml File docs/topics/impala_partitioning.xml: http://gerrit.cloudera.org:8080/#/c/7999/3/docs/topics/impala_partitioning.xml@623 PS3, Line 623: is a shortcut for partitioned tables that works on a : subset of partitions rather than the entire table. > How about: Done -- To view, visit http://gerrit.cloudera.org:8080/7999 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Ia53a6518ce5541e5c9a2cd896856ce042a599b03 Gerrit-Change-Number: 7999 Gerrit-PatchSet: 2 Gerrit-Owner: John Russell <[email protected]> Gerrit-Reviewer: Alex Behm <[email protected]> Gerrit-Reviewer: Greg Rahn <[email protected]> Gerrit-Reviewer: John Russell <[email protected]> Gerrit-Reviewer: Mostafa Mokhtar <[email protected]> Gerrit-Reviewer: Silvius Rus <[email protected]> Gerrit-Reviewer: Vuk Ercegovac <[email protected]> Gerrit-Comment-Date: Fri, 06 Oct 2017 21:26:44 +0000 Gerrit-HasComments: Yes
