StreamVByte is an integer compression technique that applies SIMD
|
||
|
|
instructions (vectorization) to Google's varint approach. The net result
|
||
|
|
is faster than other byte-oriented compression techniques.
|
||
|
|
|
||
|
|
The approach is patent-free, the code is available under the Apache License.
|
||
|
|
|
||
|
|
It includes fast differential coding.
|
||
|
|
|
||
|
|
It assumes a recent Intel processor (e.g., haswell or better, though we provide
|
||
|
|
runtime dispatching for compatibility with legacy systems) or an ARM processor
|
||
|
|
with NEON instructions (which is almost all of them).
