Can I use BRISK with Apache Cassandra, without changing Brisk or
Cassandra's code? To the best of my knowledge, DSE uses Brisk, so I am
afraid of writting hadoop process now and have to change them when I hire
DSE support.

I am not an expert in the Apache 2.0 license, but in my understanding Data
Stax modified Apache Cassandra and included modifications to it in the
version they sell. At the same time I am interested in hiring their
support, I wanna keep compatibility with the open source version
distributed in the mainstream, just in case I want to stop hiring their
support at any time.
