The following options will be removed: innodb_file_format innodb_file_format_check innodb_file_format_max innodb_large_prefix They have been deprecated in MySQL 5.7.7 (and MariaDB 10.2.2) in WL#7703. The file_format column in two INFORMATION_SCHEMA tables will be removed: innodb_sys_tablespaces innodb_sys_tables Code to update the file format tag at the end of page 0:5 (TRX_SYS_PAGE in the InnoDB system tablespace) will be removed. When initializing a new database, the bytes will remain 0. All references to the Barracuda file format will be removed. Some references to the Antelope file format (meaning ROW_FORMAT=REDUNDANT or ROW_FORMAT=COMPACT) will remain. This basically ports WL#7704 from MySQL 8.0.0 to MariaDB 10.3.1: commit 4a69dc2a95995501ed92d59a1de74414a38540c6 Author: Marko Mäkelä <marko.makela@oracle.com> Date: Wed Mar 11 22:19:49 2015 +0200
