Subject [jira] [Commented] (CASSANDRA-14866) Issue a CQL native protocol warning if SASI indexes are enabled on a table
Date Wed, 07 Nov 2018 10:32:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-14866?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16678001#comment-16678001
] 

Andrés de la Peña commented on CASSANDRA-14866:
-----------------------------------------------

[~jjirsa] We don't really need the client warning on {{SELECT}}, probably the warning on {{CREATE
INDEX}} is enough. I'm not so sure about the usefulness of the {{cassandra.yaml}} flag, but
indeed it would be more aligned with the MV behaviour.

Here is an alternative version of the patch warning only on {{CREATE INDEX}}, and with a new
{{enable_sasi_indexes}} property in {{cassandra.yaml}} (enabled by default):
||[3.11|https://github.com/adelapena/cassandra/tree/CASSANDRA-14866-mv-3.11]||[trunk|https://github.com/adelapena/cassandra/tree/CASSANDRA-14866-mv-trunk]||

[Here|https://github.com/adelapena/cassandra-dtest/commit/f0eeb1140678f3fe48129441b6dde4b36f8901eb]
are a couple of dtests for the warnings and the property. These are our very first SASI dtests
so I have put them in a separate {{sasi_test.py}} file.

[~snazy] WDYT?

> If someone enables SASI indexes then we should return a native protocol warning that
will be printed by cqlsh saying that they are beta quality still and you need to be careful
with using them in production.
> This is motivated not only by [the existing bugs and limitations|https://issues.apache.org/jira/browse/CASSANDRA-12674?jql=project%20%3D%20CASSANDRA%20AND%20status%20%3D%20Open%20AND%20component%20%3D%20sasi]
but for the fact that they haven't been extensively tested yet.
