Bayou

A framework to ensure eventual consistency among distributed systems.

Client Application used here is a Playlist of songs.

Features

The features of Bayou implemented in this protocol are:

1. Reach eventual consistency while minimizing assumptions about communication characteristics.

Design: Peer-to-peer anti-entropy for propagation of updates.

2. System support for detection of update conflicts.

Design: Dependency checks on each write.

3. Commit data to a stable value as soon as possible.

Design: Include a primary whose purpose is to commit data and set the order in which data is committed

4. Permit disconnected clients and groups to see their own updates.

Design: Clients can read tentative data with an expectation that it will be committed with the same effect if possible.

5. Provide a client with a view of the replicated data that is consistent with its own actions.

Design: Session guarantees. [Implemented - Read your writes]
