Change Description
This issue is the first official release.
To improve the performance of online analytical processing (OLAP), MySQL provides a reserved interface for the secondary engine. MySQL Pluggable Kunpeng Online Vectorized Analysis Engine (KOVAE) is a lightweight implementation of the secondary engine. KOVAE presents itself as a MySQL plugin.
Providing features of the second engine, KOVAE as a plugin has the following advantages:
- Free of intrusive modification on the MySQL source code;
- Hot-installable or hot-uninstallable without restarting or interrupting the services;
- Offloading suitable SQL statement to the second engine for execution, significantly shortening the execution time of the SQL statement through concurrent execution;
- KAEzip in Kunpeng Acceleration Engine (KAE) is utilized by the drive flushing operator to compress flushing files, saving drive space.
The concurrent acceleration technology provided by KOVAE improves the query performance of OLAP by over three times.

Kunpeng Accelerator Engine (KAE) is a hardware acceleration solution based on the Kunpeng 920 processor. It includes KAE encryption and decryption as well as KAEzip. KAEzip is the compression module of KAE. It uses the Kunpeng hardware acceleration module to implement the Deflate algorithm and works with the lossless user-mode driver framework to provide an interface for high-performance compression in gzip or zlib format.
