As it happens to be, I have been investigating the same thing in the past few days. Sqlite and rados seems to be a very natural combination. Sqlite's and rados' architecture seem to provide hooks to make it possible. Things to consider / look into:
* where to put the "backend" split, i.e., at the btree or pager level, or just implement a rados-sqlite's vfs. * increase the max #pages in a DB "file" to 48 or 64 bits (otherwise it's limited to "just" 140 TB)
* how to improve concurrency (distributed shared-memory, etc.) * a distributed locking service (chubby-like) Cheers, Rutger -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
