Most often, the internal optimizations described in InnoDB Data Storage and Compression ensure that the system runs well with compressed data. Choosing the Compressed Page Size The optimal setting of the compressed page size depends on the type and ...However, because the efficiency of compression depends on the nature of your data, you can make decisions that affect the performance of compressed tables: Which tables to ...
