MDEV-5271 support for engine-defined attributes per partition was implemented, mostly in connection with the implantation of MDEV-27106, providing the ability to specify connection attributes per partition. However, the number of other attributes that users may want to specify (like for example those listed in https://mariadb.com/kb/en/create-table/#table-options) is very limited. Ref MDEV-27545 for the reason thereof + this is a feature request to make such attributes available per partition.
Until MDEV-27545 is implemented, it needs to be made clear in the partitioning (in some "attributes per partition" section) that currently the options are limited to - those listed in
MDEV-27106 and MDEV-27545 and that other table options are not implemented yet.
