    Description

      Self-explanatory. Buffer size can be provided in number of blocks. Could be implemented trivially with heap storage and several BlockReaders or could have more advanced features like:

      • logic to ensure that blocks are not pulled from the same Datanode(s).
      • local filesystem store for buffered blocks
      • adaptive parallelism
