Why it matters

This feature addresses the limitation of not being able to back up compressed in-memory tables, ensuring that backups fully capture all table types and data states. It enhances data safety and disaster recovery options for users utilizing compressed in-memory tables.

How to use it

Backups including compressed in-memory tables are now supported transparently through existing backup commands and workflows without additional configuration.
