amhiggin / raft-membership-service

RAFT consensus-based group membership management service, implemented in Python.

Raft Membership Service

A membership management system for a set of distributed nodes.

The system spec requires a number of services to be provided, including:

• Forming, joining, and leaving groups
• Monitoring group members and reporting member failures to the remaining members
• Returning the current group membership when required
• Possibly providing a ranking of members (e.g. based on age)

The spec requires that each member of the managed group should have a consistent view of group membership at any given time, i.e. at a minimum, they should see the same sequence of changes to group membership over time.

Note: Entitlements/identity management are not catered for as part of this service.
