rqlite -- a replicated SQLite database.
|
|
|
|
rqlite is a distributed system that provides a replicated SQLite database.
|
|
rqlite is written in Go and uses Raft to achieve consensus across all the
|
|
instances of the SQLite databases. rqlite ensures that every change made to
|
|
the database is made to a majority of underlying SQLite files, or none-at-all.
