Hi all,
I use pycassa and I want to store lists and tuples in cassandra by
serializing them using MessagePack. Seems like custom data type is what I
need. Here is data type I created:
##########################################
class MyListType(CassandraType):
@staticmethod
def pack(value):
return msgpack.packb(value)
@staticmethod
def unpack(value):
return msgpack.unpackb(value)
##########################################
Now I'm creating a new column family and use instance of this class in
column_validation_classes but unsuccessful. It raises
"InvalidRequestException: InvalidRequestException(why="Unable to find
abstract-type class 'org.apache.cassandra.db.marshal.MyListType'")".
What I'm doing wrong? How to do it properly?
Thanks.
