Jonathan Ellis commented on CASSANDRA-570:
------------------------------------------
That would be fine, although it would require subcolumn indexing to really be
useful.
> Pattern matching / better filtering for column / super column names for

> Key: CASSANDRA-570
> URL: https://issues.apache.org/jira/browse/CASSANDRA-570
> Project: Cassandra
> Issue Type: Improvement
> Affects Versions: 0.5, 0.9
> Reporter: Suhail Doshi
>
> It would be useful to be able to pattern match or wildcard in a column name.
> The problem is sometimes you need more depth where supercolumns are not
> enough. The hack around solution is prefixing things but when you prefix
> things you realize you need a better way to filter through the prefixed data.
> I am voting for a way to pattern match or permit some kind of wildcarding in
> the column if possible.
> For example:
> column name="prefix_20091122_male"
> column name="prefix2_20091122_female"
> Cassandra could be used in complex data situation for people who want to grab
> all data from the date: 20091122 or grab all data from the date: "20091122"
> and that is of type male or female through some kind of wildcard / pattern
> matching scheme.
> I won't propose one because I do not understand Cassandra well enough to but
> it seems like this may be possible and worth a discussion.
