Subject [jira] Commented: (CASSANDRA-1204) CliClient Support for add, drop, and rename should be added for keyspace and column family

I'm looking over your comments, and a bit confused (or
maybe I just don't agree) with the create keyspace syntax you are
suggesting. It seems that you are suggesting the following:

        create keyspace <keyspace>[placement_strategy=value ]
        create keyspace <keyspace>[placement_strategy=value
[replication_factor = value ] ]

        eg:
          create keyspace foo[placement_strategy=RackUnawareStrategy]
          create keyspace foo[placement_strategy=RackUnawareStrategy
[replication_factor = 3 ]]
{quote}

No, I was suggesting something like...

{noformat}
create keyspace Foo with placement = RackUnawareStrategy and replication_factor = 3
create column family Bar with comparator = BytesType and rowscached = 10000
{noformat}

{quote}
But this looks unlike the syntax for the gets and sets and looks
somewhat messier than below this:

          create keyspace foo[RackUnawareStrategy]
          create keyspace foo[RackUnawareStrategy][3]
{quote}

Right. This syntax is similar to how lists are subscripted in some languages, which is a pretty
good analogy for the data access bits (get and set), but doesn't make any sense here IMO.

So, am I reading you right, if so, how do you feel about the above
modifications to your corrections?

> Should add support for the add, drop, and rename operations to keyspace and column family
in the CliClient.
> Eg:
> add keyspace <keyspace>                                      Add a new keyspace.
> add column family <cf>[comparator]                      Add a new column family.
> drop keyspace <keyspace>                                      Delete a keyspace.
> drop column family <cf>                                  Delete a column family.
> rename keyspace <keyspace>=<keyspace_new_name>                Rename a keyspace.
> rename column family <name>=<new_name>                   Rename a column
family.
> Note: I have patch built for this, but drop keyspace corrupts the schema and prevents
the node from restarting due to a bug elsewhere (see: CASSANDRA-1203)
