Stream VByte: Faster Byte-Oriented Integer Compression
Daniel Lemire, Nathan Kurz, Christoph Rupp
Arrays of integers are often compressed in search engines. Though there are many ways to compress integers, we are interested in the popular byte-oriented integer compression techn…
Vectorized VByte Decoding
Jeff Plaisance, Nathan Kurz, Daniel Lemire
We consider the ubiquitous technique of VByte compression, which represents each integer as a variable length sequence of bytes. The low 7 bits of each byte encode a portion of the…
SIMD Compression and the Intersection of Sorted Integers
Daniel Lemire, Leonid Boytsov, Nathan Kurz
Sorted lists of integers are commonly used in inverted indexes and database systems. They are often compressed in memory. We can use the SIMD instructions available in common proce…
