> Intel® In-Memory Analytics Accelerator (Intel® IAA) is a hardware accelerator
> available in the upcoming generation of Intel® Xeon® Scalable processors
> ("Sapphire Rapids"). Its goal is to speed up common operations in analytics
> like data (de)compression and filtering. It support decoding of Parquet RLE
> format. We add new codec which utilizes the Intel® IAA offloading technology
> to provide a high-performance RLE decode implementation. The codec uses the
> [Intel® Query Processing Library (QPL)|https://github.com/intel/qpl] which
> abstracts access to the hardware accelerator. The new solution provides in
> general higher performance against current solution, and also consume less
> CPU.
