Date Fri, 18 May 2012 19:51:09 GMT


Pavel Yaskevich updated CASSANDRA-3794:

Made a migration from int to uuid, made sure that all SerializationTests pass (and all other
tests) and schema is merged correctly in the situations described in previous comments.

> Change ColumnFamily identifiers to be UUIDs instead of sequential Integers. Would be
useful in the situation when nodes simultaneously trying to create ColumnFamilies.
