CassandraCountPartitionReader

case class CassandraCountPartitionReader(connector: CassandraConnector, tableDef: TableDef, schema: StructType, readConf: ReadConf, queryParts: CqlQueryParts, partition: CassandraPartition[Any, _ <: Token[Any]]) extends CassandraPartitionReaderBase with Product with Serializable

Runs a COUNT(*) query instead of a request for actual rows Takes the results and returns that many empty internal rows
