--------------------------------------------
Summary: improve ALTER TABLE
Key: CASSANDRA-4696
URL: https://issues.apache.org/jira/browse/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:
{noformat}
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.
