It has been discussed at
GORA-81, and a kind of fix has been committed as a part of GORA-138 patch.
Since it is one of the main functionalities of gora-cassandra to handle Serializers, it seems a good idea to separate those code from store and query packages.
I will be attaching my patch shortly.
1) Utf8Serializer makes simple to handle Type.STRING;
2) GoraSerializerTypeInferer is a single point go get Serializer, and it is extensible to support additional types in future;
3) Type.BOOLEAN is supported.
