 Description   

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

As far as I can see, there is no mapping for TimeUUIDType in the current implementation.

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.

Changing status to Wont-Fix as there is no work planned on Cassandra-SE currently
