[jira] [Created] (BEAM-683) Make BZIP compressed files splittable

Tim Sears created BEAM-683:
------------------------------

             Summary: Make BZIP compressed files splittable 
                 Key: BEAM-683
                 URL: https://issues.apache.org/jira/browse/BEAM-683
             Project: Beam
          Issue Type: Wish
            Reporter: Tim Sears
            Priority: Minor


Bzip2 is compressed as blocks, so it should be possible to do dynamic splitting. To do this: Seek to a location in the bzip, then keep seeking until you find the 6 byte block-start sequence 0x314159265359 (which is the 12 digit approximation of pi). You can use a bzip2 decompressor from that point onwards.
