Since MariaDB Server 10.5.1, a build configuration is supported but not enabled in our packages:
This will depend on libpmem-dev and introduce a small library dependency to the generated server package.
I think that we should enable Persistent Memory support in MariaDB 10.6 on all applicable operating systems. Having the InnoDB redo log in a mount -o dax device should vastly reduce the transaction commit latency. This task would be a prerequisite for that.
