Hi guys
My column family defination:
create column family tc_audit_trail
with key_validation_class = TimeUUIDType
and comparator = UTF8Type
and column_metadata = [
{column_name: userid, validation_class: LongType,index_name : 'user', index_type : 0},
{column_name: entityid, validation_class: LongType,index_name : 'entity', index_type : 0},
{column_name: entitytype, validation_class: UTF8Type,index_name : 'entityType', index_type : 0},
{column_name: logtype, validation_class: UTF8Type,index_name : 'logType', index_type : 0},
{column_name: comment, validation_class: UTF8Type}
];
Maria DB defination:
CREATE TABLE tc_audit_trail ( `key` bigint(6) DEFAULT 0 NOT NULL, userid bigint(19), entityid bigint(19), entitytype varchar(60), logtype varchar(60), comment text(65535), PRIMARY KEY (`key`) ) ENGINE=CASSANDRA DEFAULT `thrift_host`='127.0.0.1' `keyspace`='timescity' `column_family`='tc_audit_trail'
error: ERROR: Internal error: Failed to map PRIMARY KEY to datatype org.apache.cassandra.db.marshal.TimeUUIDType Error Code: 1815

when we can expect to be implemented? Also for development process how can build mysql from source. so that i can contribute in cassandra SE.
There are a lot of other bugs/tasks which we believe have higher impact. As a consequence, fixing this one is not on anyone's todo at the moment. So, we can't promise any particular date.
As for development: one can get the source from https://github.com/MariaDB/server.
Cassandra SE can (and will) only be built if Thrift library is installed.
The build process is:
Run "cmake ." in the source tree. Look for lines like
-- Performing Test CASSANDRASE_OK -- Performing Test CASSANDRASE_OK - Success
If you have them, you can run "make" and MariaDB will be built with the cassandra engine.
In case you're going to expend a lot of effort on the Cassandra engine, be sure to read http://s.petrunia.net/blog/?p=88 first.
As far as I can see, there is no mapping for TimeUUIDType in the current implementation.
