The purpose of this ticket is to achieve the following enhancements to OpenSAF
cluster management/membership:
- Perform high level node monitoring(heartbeating)
- Enhanced split-brain avoidance techniques.
RAFT is being considered for implementing the above cluster management
enhancements.
.
The scope of this ticket includes the following:
(a) Implement RAFT and/or RAFT adaptation layer that provides interfaces for
- adding/removing nodes to the cluster membership
- querying leader
- callbacks notifying about new leader
- read/write interface
- notification of nodes joining/leaving the cluster membership
Note: Yet to be seen if a leader yield interface is necessary
(b) an interface that alows invoking a fencing mechanism
(c) an interface that allows invoking an arbitration mechanism
