Read settings for RDD

splitSize

number of Cassandra partitions to be read in a single Spark task

fetchSize

number of CQL rows to fetch in a single round-trip to Cassandra

consistencyLevel

consistency level for reads, default LOCAL_ONE; higher consistency level will disable data-locality

taskMetricsEnabled

whether or not enable task metrics updates (requires Spark 1.2+)
