The Intel® Query Processing Library (Intel® QPL) is an open-source library to provide high-performance query processing operations on Intel CPUs. Intel® QPL is aimed to support capabilities of the new Intel® In-Memory Analytics Accelerator (Intel® IAA) available on Next Generation Intel® Xeon® Scalable processors, codenamed Sapphire Rapids processor, such as very high throughput compression and decompression combined with primitive analytic functions, as well as to provide highly-optimized SW fallback on other Intel CPUs. Intel QPL primarily targets applications such as big-data and in-memory analytic databases.

Intel QPL provides Low-Level C API. You can use it from C/C++ applications. You can also find Java* bindings in the qpl-java project. Refer to its documentation for details.
