AVRO related imports should only be resided in AvroSerializer class. Native datastax related imports should only be resided in NativeSerializer class. That way CassandraStore is decoupled from AVRO related dependencies. I went through your code this AVRO import has only been used in one location in persistentSchema class level variable. I think you can easily get rid of this bit of code change, may be you change CassandraSerializer.getSerializer() method by passing BeanFactory<K, T> beanFactory directly rather assigning to class level variable. I think one this type of design would be start point, one day Gora should be refactored to support pluggable serializers not just AVRO. WDYT @lewismc
