      Description

      From https://mariadb.zulipchat.com/#narrow/stream/118759-general/topic/innodb_data_home_dir/near/269694298

      In MariaDB we do not allow the creation of ROW_FORMAT=COMPRESSED temporary tables. All temporary tables will be uncompressed. Writes to those temporary tables will be avoided: MDEV-12227, MDEV-15528.

      https://mariadb.com/kb/en/innodb-temporary-tablespaces/ states "when compressed, the temporary table is written to a dedicated temporary tablespace for that table" which is wrong. That probably holds true for MySQL 5.7, but not for MariaDB.
