FoundationDB as a Storage Engine for Irmin
Talkat FoundationDB Summit 2019 · on Monday, 2019-11-18· at 14:10· Grand Ballroom 8, Marriott Marquis San Diego Marina·
summary
irmin-fdb implements Irmin storage on FoundationDB and ships OCaml FoundationDB bindings so Irmin (an OCaml Git-like DB) can use FoundationDB as a horizontally scalable engine. It implements CAS operations, transactional test-and-set semantics, and a watch mechanism that appends version-stamped entries to a changelog and uses an internal cursor with periodic cleanup. The engine passes Irmin’s extensive test suite, shows comparable preliminary benchmarks, and still needs work to pass the full binding tests and explore leveraging FoundationDB’s full history for efficient change feeds.
