The Spark Cassandra Connector 3.0.0 is a huge milestone for manipulating Apache Cassandra™ data in Apache Spark™!
The 3.0.0 release contains Spark 3.0.x support, including the new Catalog implementation. To quickly start with Catalogs see this short demo, read the DataFrames documentation page, or watch this presentation. To give you a hint what's now possible with the new Cassandra Catalog:
Like the previous release, this one also comes in two flavors: spark-cassandra-connector and spark-cassandra-connector-assembly. The former is not assembled: all of its dependencies are listed in the corresponding pom.xml file. The latter is an assembled JAR with some of the dependencies shaded.
See the full release note page here.
