Method Detail

store

<T> void store(scala.collection.Iterator<T> iter)

Store an iterator of received data as a data block into Spark's memory.

store

void store(java.nio.ByteBuffer bytes)

Store the bytes of received data as a data block into Spark's memory. Note that the data in the ByteBuffer must be serialized using the same serializer that Spark is configured to use.

store

<T> void store(T item)

Store a single item of received data to Spark's memory. These single items will be aggregated together into data blocks before being pushed into Spark's memory.
