Subject [jira] [Commented] (CASSANDRA-12373) 3.0 breaks CQL compatibility with super columns families
Date Wed, 23 Aug 2017 13:40:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-12373?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16138350#comment-16138350
] 

Sylvain Lebresne commented on CASSANDRA-12373:
----------------------------------------------

bq. but in 3.x we started exposing the defined columns as "static" and the undefined ones
as column1/value.

That's not exactly true. It's how we handle CS tables internally, but it's not how they are
exposed. That's where CASSANDRA-10857 come in, as it's goal is exactly to allow exposing that
internal layout and this will work for all compact tables, SCF included (and yes, all the
data will be exposed this way).

> This is a follow-up to CASSANDRA-12335 to fix the CQL side of super column compatibility.
> The details and a proposed solution can be found in the comments of CASSANDRA-12335 but
the crux of the issue is that super column famillies show up differently in CQL in 3.0.x/3.x
compared to 2.x, hence breaking backward compatibilty.
