Subject RE: Using Cli to create a column family with column name metadata question
Date Tue, 08 Nov 2011 01:36:45 GMT
Hi,

Thanks for the replay. I'm not talking about the column name. I'm talking about the column
metadata's column name. Right now cli can't not display the column's meta name correctly if
the comparator type is not UTF8.

Regards,

Arsene

[Moving to user@]

Because Cassandra's sparse data model supports using rows as "materialized views," having
non-UTF8 column names is common and totally valid.

Cassandra's CLI CliClient.java code when trying to create a column family with column name
metadata. It is based on CF's comparator type to convert the name String to ByteBuffer. I'm
wondering if there is any particular reason for this? For the column name metadata shouldn't
it be easier just to all use UTF8Type. Because if CF's comparator is other than UTF8Type,
it is hard to convert the column name back.
