I'd like to thank the PyTables community that have collaborated in the exhaustive testing of Blosc. With an aggregate amount of more than 300 TB of different datasets compressed and decompressed successfully, I can say that Blosc is pretty safe now and ready for production purposes.
Other important contributions:
- Valentin Haenel did a terrific work implementing the support for the Snappy compression, fixing typos and improving docs and the plotting script.
- Thibault North, with ideas from Oscar Villellas, contributed a way to call Blosc from different threads in a safe way. Christopher Speller introduced contexts so that a global lock is not necessary anymore.
- The CMake support was initially contributed by Thibault North, and Antonio Valentino and Mark Wiebe made great enhancements to it.
- Christopher Speller also introduced the two new '_ctx' calls to avoid the use of the blosc_init() and blosc_destroy().
- Jack Pappas contributed important portability enhancements, specially runtime and cross-platform detection of SSE2/AVX2 as well as high precision timers (HPET) for the benchmark program.
- @littlezhou implemented the AVX2 version of shuffle routines.
- Julian Taylor contributed a way to detect AVX2 in runtime and calling the appropriate routines only if the underlying hardware supports it.
- Kiyo Masui for relicensing his bitshuffle project for allowing the inclusion of part of his code in Blosc.
