-----------------------------------------
Summary: Prototype Raft implementation port to a separate
zero-dependency Ignite module
Key: IGNITE-13798
URL: https://issues.apache.org/jira/browse/IGNITE-13798
Project: Ignite
Issue Type: New Feature
Reporter: Alexey Goncharuk
Assignee: Alexey Goncharuk
We need to check whether it is reasonable and feasible to port the etcd Raft
implementation [1] to Java, maintaining the same API interaction model:
* Raft instance is a single-threaded state machine with methods to accept
messages, return progress to be processed by a raft client, and tick callback
* Raft instance does not actively send messages, not does it actively write to
persistent log or the state machine
The implementation should demonstrate how the module will be used with omitted
components: Raft Log, State Machine, Messaging, Timer.
The implementation must cover:
* Ability to provide leader/follower callbacks
* Ability to read linearizable and relaxed commit indexes
The implementation may cover:
* Replication group reconfiguration
The implementation prototype does not cover:
* Multi-raft groups
* Asynchronous state machine mutation
