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.
