- 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
- 16/32 and :new: 64 bits integer lists
- Full Range 16/32 and :new: 64 bits integer lists
<p>
+ **Features**
- Scalar **"Variable Byte"** faster and more efficient than any other implementation
