Change subject: [DOCS] Clarification on admission control and DDL statements ...................................................................... Patch Set 1: I think this is somehow much more confusing than it should be. The facts are: * queries submitted to a given session are executed serially, DDL or not * DDLs are not part of admission control * Naturally, this means that any query, including DDLs, that the client submits in a session that has a query queued, will not execute (but this behaviour has nothing to do with admission control). The tricky part is that while the example query is queued, it is possible to open a new session and drop the table the queued query would refer to. I think we should have a page somewhere (probably here?) to separate these behaviours (queued due to serial exec vs queued due to admission control), and spell out how this relates to DDLs specifically (the scenario above is a good example IMO). -- To view, visit http://gerrit.cloudera.org:8080/10829 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I2e3e82bd34e88e7a13de1864aeb97f01023bc715 Gerrit-Change-Number: 10829 Gerrit-PatchSet: 1 Gerrit-Owner: Alex Rodoni <[email protected]> Gerrit-Reviewer: Balazs Jeszenszky <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Comment-Date: Tue, 26 Jun 2018 21:48:33 +0000 Gerrit-HasComments: No
