--------------------------------
Summary: Add Intel®-IAA/QPL-based Parquet RLE Decode
Key: ARROW-17884
URL: https://issues.apache.org/jira/browse/ARROW-17884
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: zhaoyaqi
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.
