ReadConf

case class ReadConf(splitCount: Option[Int] = scala.None, splitSizeInMB: Int = ReadConf.SplitSizeInMBParam.default, fetchSizeInRows: Int = ..., consistencyLevel: ConsistencyLevel = ..., taskMetricsEnabled: Boolean = ReadConf.TaskMetricParam.default) extends Product with Serializable

Read settings for RDD

splitCount

number of partitions to divide the data into; unset by default

splitSizeInMB

size of Cassandra data to be read in a single Spark task; determines the number of partitions, but ignored if splitCount is set

fetchSizeInRows

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+)
