Subject [jira] [Commented] (CASSANDRA-11067) Improve SASI syntax
Date Tue, 26 Jan 2016 18:19:39 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11067?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15117681#comment-15117681

Jordan West commented on CASSANDRA-11067:
-----------------------------------------

bq. other than the fact that is new and experimental and unproven in the real world yet?

I think SASI is as, or more, proven than any change in the 3.x releases. Its been in production
for longer than any 3.x feature and most of the changes for 3.x were surface-level integration
changes as [~xedin] mentioned.

bq. The fact that a SASI index needs to be "CUSTOM" and an explicit class name is needed feels
a little hokey to me.

Agreed but we decided not to change this to ease the merge and because the sstable's format
is not extendable easily, currently. Also, this the case for any non-default index class.
I think it would be great to SASI become the default implementation or to have an easier way
to specify which implementation to use.

> 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 =.
