- No other "Integer Compression" compress or decompress faster with better compression
- Direct Access is several times faster than other libraries
- Usage in C/C++ as easy as memcpy
- :new: Integrated differential encoding/decoding for sorted integer lists
- :sparkles: Full range 16/32, :new: 64 bits integer lists and :new: Floating point support
- :new: Integrated (SIMD) differential/Zigzag encoding/decoding for sorted/unsorted integer lists
- :sparkles: Full range 16/32, :new: 64 bits integer lists and :new: Floating point
- :+1: Java Critical Native Interface. Access TurboPFor incl. SIMD from Java as fast as calling from C.
- Compress better and faster than special binary compressors like blosc

- :sparkles: Scalar **"Variable Byte"** faster and more efficient than any other implementation

- **Novel** **"TurboPFor"** (Patched Frame-of-Reference,PFor/PForDelta) scheme with **direct access** or bulk decoding.
Outstanding compression and speed. More efficient than **ANY** other "integer compression" scheme.
