KAEzip Compression and Decompression Optimization

Application scenario: KAEzip is suited for OLAP queries that involve a large number of compression and decompression operations.

Technical principle: This feature uses the Kunpeng hardware acceleration module to implement the deflate and inflate algorithms and works with the lossless userspace driver framework to provide interfaces for high-performance compression in gzip or zlib format.

Figure 1 shows the logical architecture of KAE.

Performance metric: KAEzip can improve OLAP query performance by 10% in heavy I/O scenarios where only one request is processed at a time before the hardware bottleneck is reached.
