The buffer is available as a standalone reagent or as part of larger kits from Buffer RDD (35 ml) A colorless, odorless liquid with a pH typically between 6
It is not a separate RDD type but a of any RDD — designed to trade storage space for computation speed. A proper understanding helps in tuning memory usage and fault tolerance in Spark applications. what is the composition of buffer rdd
