Subject [jira] [Created] (CASSANDRA-4696) improve ALTER TABLE
Date Fri, 21 Sep 2012 07:01:08 GMT
Michael Krumpholz created CASSANDRA-4696:

             Summary: improve ALTER TABLE
                 Key: CASSANDRA-4696
             Project: Cassandra
          Issue Type: Improvement
    Affects Versions: 1.1.5
            Reporter: Michael Krumpholz

Please improve the ALTER TABLE statement so that it automatically checks the data in the table
against the new data type to change to. I know that it's in the docs that this is the current
state and not checked. It may be the easiest and fastest way for implementation for now but
it should be improved in the future.

docs on ALTER:
The column must already have a type in the column family metadata. The column may or may not
already exist in current rows (no validation of existing data occurs). The bytes stored in
values for that column remain unchanged, and if existing data is not deserializable according
to the new type, your CQL driver or interface might report errors.
