Subject [jira] Commented: (CASSANDRA-1185) determine legal keyspace/column family names and validate
Date Sat, 12 Jun 2010 16:11:13 GMT


Jeremy Hanna commented on CASSANDRA-1185:

Is there a way we could divorce names in Cassandra from names on the filesystem?  It just
seems like an odd implementation specific thing.

Maybe marking up special characters in a standard way?

I'm not sure why they are ties together in the first place though.

No matter what though validation and error messages are needed- I was just curious.

> Since keyspace and column family names are used to derive the directory and filenames
where data is stored, so some thought should be given to which characters are legally allowed.
Then, node-side validation should prevent the creation of namespaces that contain these characters,
and produce a meaningful error message in the process.
