Database as Filesystem

Explore an innovative approach to filesystem design in this 22-minute conference talk from linux.conf.au. Delve into the concept of using database engines like Postgres or MariaDB on raw partitions to build POSIX file system semantics. Learn about the potential advantages of this method, including replication and ACID properties, and how it compares to traditional network file systems. Discover the speaker's implementation progress and plans for measuring performance and durability. Gain insights into the schema, functionality, and non-POSIX semantics of this database-as-filesystem approach. Consider the new possibilities this design could unlock for file systems and understand its potential impact on storage technology.
