Subject [jira] [Commented] (CASSANDRA-11067) Improve SASI syntax
Date Thu, 28 Jan 2016 03:36:39 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11067?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15120697#comment-15120697

Pavel Yaskevich commented on CASSANDRA-11067:
---------------------------------------------

[~beobal] I've updated doc/SASI.md with LIKE support and fixed a typo in Cql.g, also I've
noticed that loading of the SASI indexes on startup is missing so I've pushed that too into
CASSANDRA-11067 branch (and fixed use of IntervalTree on the way) and rebased everything with
the latest trunk.

> I think everyone agrees that a LIKE operator would be ideal, but that's probably not
in scope for an initial 3.4 release.
> Still, I'm uncomfortable with the initial approach of overloading = to mean "satisfies
index expression."  The problem is that it will be very difficult to back out of this behavior
once people are using it.
> I propose adding a new operator in the interim instead.  Call it MATCHES, maybe.  With
the exact same behavior that SASI currently exposes, just with a separate operator rather
than being rolled into =.
