SQL on Ceph

FOSDEM 2023

Ceph was originally designed to fill a need for a distributed file system within scientific computing environments but has since grown to become a dominant unified software-defined distribute storage system. Today, it is also notably used as an enterprise-quality block device and object store provider. This talk will cover the new development of an SQLite Virtual File System (VFS) on top of Ceph's distributed object store (RADOS). I will show how SQL can now be run on Ceph for both its internal use and for new application storage requirements.

The talk will cover:

Existing storage abstractions on Ceph.
Very brief introduction to RADOS.
Very brief introduction to SQLite and its VFS abstraction.
The libcephsqlite library and how it works.
How to use libcephsqlite in an application.
How Ceph uses libcephsqlite.
What's in the future?
