    A wrapper for a continuous processing data reader, including a reading queue and epoch markers.

    A wrapper for a continuous processing data reader, including a reading queue and epoch markers.

    This will be instantiated once per partition - successive calls to compute() in the ContinuousDataSourceRDD will reuse the same reader. This is required to get continuity of offsets across epochs. Each compute() should call the next() method here until null is returned.

class DataReaderThread extends Thread with Logging

The data component of ContinuousQueuedDataReader. Pushes (row, offset) to the queue when a new row arrives to the ContinuousPartitionReader.
