flotilla is a Go library typically used in Architecture applications. flotilla has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Flotilla is a consensus, embedded and programmable database, intended as a building block for distributed databases. Consensus — All changes to a Flotilla database are replicated in a consistent order across all machines in the Flotilla cluster. Embedded — All read transactions are from local storage. Doesn’t expose any external network APIs (that’s your job). Programmable — All write modifications are done via user-defined functions. This is done to process the same state machine in the same order on all machines. There are example user-defined functions in lib.go and the examples on this page. Flotilla is based on a straightforward combination of the Raft algorithm (link) with the LMDB embedded database. In Raft, all cluster operations happen in a single, defined order. Operations don’t have to be idempotent, because they’ll be executed in the same order in each machine, guaranteeing the same final state. This means we can give each write transaction a single atomic and consistent view of the database, while allowing simultaneous readers due to LMDB’s MVCC mechanisms.
