[GitHub] [beam] kennknowles opened a new issue, #18050: Make BZIP compressed files splittable

kennknowles opened a new issue, #18050:
URL: https://github.com/apache/beam/issues/18050

   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.
