14.6 InnoDB Table and Page Compression

This section provides information about the InnoDB table compression and InnoDB page compression features. The page compression feature, referred to as transparent page compression, was introduced in MySQL 5.7.8.

Using the compression features of InnoDB, you can create tables where the data is stored in compressed form. Compression can help to improve both raw performance and scalability. The compression means less data is transferred between disk and memory, and takes up less space on disk and in memory. The benefits are amplified for tables with secondary indexes, because index data is compressed also. Compression can be especially important for SSD storage devices, because they tend to have lower capacity than HDD devices.
