Change subject: [DOCS] Clarification on admission control and DDL statements ...................................................................... Patch Set 2: > 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). I created a new section at the end and made an attempt to address the confusion. -- 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: 2 Gerrit-Owner: Alex Rodoni <[email protected]> Gerrit-Reviewer: Alex Rodoni <[email protected]> Gerrit-Reviewer: Balazs Jeszenszky <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Comment-Date: Tue, 26 Jun 2018 23:06:19 +0000 Gerrit-HasComments: No
