Hi Oleg,
Stratio Deep is just a library you must include in your Spark deployment
so it doesn't guarantee any high availability at all. To achieve HA you
must use Mesos or any other 3rd party resource manager.
Stratio doesn't currently support PySpark, just Scala and Java. Perhaps
in the future...
It should be ready for production use, but like always please test
before on a testing environment ;-)
As far as I know, the Datastax connector uses thrift to connect Spark
with Cassandra although thrift is already deprecated, could someone
confirm this point?
