Hello Shahriyar, Thank you for the report. Imho user-created temporary tables and on-disk internal temporary tables are created in a shared temporary tablespace and per documented limitation under "Page Compression Limitations and Usage Notes" - Page compression is not supported for tables that reside in shared tablespaces, which include the system tablespace, the temporary tablespace, and general tablespaces. - https://dev.mysql.com/doc/refman/5.7/en/innodb-page-compression.html Thanks, Umesh
