Cassandra as a System Data Store
Support for using Cassandra as a system data store is being deprecated in our next minor release. Support for Cassandra as an embedded language and database will continue as before.
Spark-HPCC Connector Integration
The HPCC integrated Spark plugin is no longer supported as of version 9.0.0 in favor of stand-alone user-managed Spark clusters linked to the HPCC platform using the Spark-HPCC connector.
If you have an existing deployment of the HPCC platform with the Spark-HPCC plugin and wish to upgrade, you will need to make some configuration changes. You'll only need to do this once for each environment where Spark integration was configured.
