ActorDB


ActorDB is a distributed relational SQL database, which is strongly consistent, massively concurrent, and horizontally scalable. It supports no single point of failure and uses no global read or write locks. To achieve the features provided, ActorDB uses Raft distributed consensus algorithm on top of an existing battle-tested and stable SQL database engine. ActorDB splits the dataset into small independent chunks, which is inspired by the "Actor Model".[03][04]

History[05][06][07]


Started with the project Emit Cloud, which is a file synchronization application like Dropbox, the developers at Biokoda found problems in achieving no single point of failure and horizontal scalability. To solve the problem, developers at Biokoda extended SQLite's WAL format to implement Raft. In the later versions, LMDB is used as the storage engine for ActorDB. ActorDB was first launched in 2015. The latest official stable release is 0.10.27 (Jan 2019).

Checkpoints[08]


ActorDB does not require checkpoints from WAL to the main database file.
