Implement RaftNode.replicate(List<Object> operations)

[metanet]

Explore Implementing a new API to allow users to replicate an operation batch rather than one operation. This might be beneficial for performance reasons if a customer batches operations before committing them via Raft.

Hi @metanet ,
are you still working on this issue, or is it available for contributions? :)

[metanet]

Go for it. I am not working on it at the moment.

@metanet We are talking here about atomic batches, right? So one operation in the batch is committed iff all the other operations are committed.
If that is the case, then I would go with introducing a new type of operation, a BatchOperation, that stores the list of operations of a batch. The commitment status and log position of such a BatchOperation is then equal to the commitment status and position for all its containing operations. For applying a BatchOperation, we then would require the state machine to do this also atomically. As far as I see it, with that we would get atomicity for such a batch. What do you think?

Yup, this is exactly what i had in mind. The easiest way to atomically commit a list of operations is to wrap them in one object and commit it.
