I'm evaluating caching options for Datomic Pro. Valcache sounds like a great fit, but there is one thing that might be a showstopper.

The Prerequisites docs says that "Valcache relies on an SSD with the strictatime and lazytime flags set". This requirement I can meet pretty easily by remounting the disk on the hosts running the peers.

Now, the applications that are Datomic peers, who would be the users of these Valcaches, run as Docker containers in a Docker Swarm. The idea is to mount the Valcache as a Docker bind mount.

Would this work? The underlaying SSD disk would be mounted with strictatime and lazytime, but would whatever mechanism that requires these flags to be set work through a Docker bind mount?
