paul cannon commented on CASSANDRA-4380:
----------------------------------------
bq. for 1.2, provided you use the system.schema_columnfamilies table, it should
(almost) always be possible to create a valid CQL3 definition from an existing
CF
Could you elaborate on how that should be done? Say I made the following in
CQL2:
{noformat}
CREATE TABLE foo (t text PRIMARY KEY, f float, x uuid) WITH
default_validation=timestamp;
{noformat}
If that can be recreated in CQL 3, then I've missed a development somewhere.
bq. The Cassandra already does that (so that you can always access thrift CF
from CQL3), see CFDefinition.java. It could be worth using the same made-up
names here.
That's good to know. We should probably make that new ticket then.
> CQLSH: describe command doesn't output valid CQL command.
