Let us introduce the parameter innodb_read_only_compressed that is ON by default, making any ROW_FORMAT=COMPRESSED tables read-only. I developed the ROW_FORMAT=COMPRESSED format based on Heikki Tuuri's rough design between 2005 and 2008. It might have been a good idea back then, but no proper benchmarks were ever run to validate the design or the implementation. The format has been more or less obsolete for years. It limits innodb_page_size to 16384 bytes (the default), and instant ALTER TABLE is not supported. This is the first step towards deprecating and removing write support for ROW_FORMAT=COMPRESSED tables.
