[jira] [Commented] (CASSANDRA-11067) Improve SASI syntax
[ https://issues.apache.org/jira/browse/CASSANDRA-11067?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15211854#comment-15211854 ]
Olivier Michallat commented on CASSANDRA-11067:
-----------------------------------------------
It's not possible to bind LIKE's argument in a prepared statement (the grammar requires a string literal). Is this an oversight or do we have any reason not to allow it?

> 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 =.
