MDEV-7261 - Backport the default autosized value of "table_definition_cache" from MySQL 5.6.8+
Fixed table_definition_cache auto-sizing. Note that this patch doesn't address broken PFS auto-sizing.
Do you plan to address it after you've broken it? How? PFS autosizing relies on table_definition_cache, table_open_cache, max_connections, open_files_limit.
The only options that is autosized prior to PFS autosizing was table_defintion_cache. Even this option was autosized incorrectly. So I didn't break it, it was broken even prior to this patch. In 5.7 all these options are marked EARLY and are autosized before PFS autosizing. Regards, Sergey
