- * Notes:
- * 1) If we try to store the raw ByteBuffer from record.getData(),
the Spark Streaming
- * Receiver.store(ByteBuffer) attempts to deserialize the
ByteBuffer using the
- * internally-configured Spark serializer (kryo, etc).
- * 2) This is not desirable, so we instead store a raw Array[Byte]
and decouple
- * ourselves from Spark's internal serialization strategy.
- * 3) For performance, the BlockGenerator is asynchronously
queuing elements within its
- * memory before creating blocks. This prevents the small
block scenario, but requires
- * that you register callbacks to know when a block has been
generated and stored
- * (WAL is sufficient for storage) before can checkpoint back
to the source.
