Proposed: Implement Ra in V-Sekai

Context

V-Sekai, a VR social network, needs reliable state machines for data persistence. Current system may struggle with data consistency and failure recovery.

Problem

User experience can be disrupted due to potential data inconsistencies and loss, leading to issues like lost interactions and inconsistent virtual states.

Solution

Implement Ra, a Raft implementation by Team RabbitMQ, in any Erlang or Elixir project. Ra enables persistent, fault-tolerant, replicated state machines.

Benefits

Fault Tolerance: Ra ensures data consistency via leader election and log replication.
Efficiency: Supports log compaction and snapshot installation.
Scalability: Suitable for large-scale applications like V-Sekai.

Downsides

Learning Curve: Developers need to learn Ra and the Raft consensus algorithm.
Dependency: Ra could increase project complexity.

Alternatives

Other solutions like CRDTs were considered but have major shortcomings.

Infrequent Use Case

In small distributed systems with rare failures, Ra’s benefits may not be fully realized.

Implementation

The V-Sekai team will implement Ra.
