How to send data from follower to cluster leader

[faithware]

Hi, Is there any way to send data from a follow to a cluster manager?
Does this has to be implemented separately of the raft server?

Thank you

Hi @faithware

There is no protocol to send a custom message from follower to leader. The only message that followers send is a vote (pre-vote) request. If you want to do it, that needs to be implemented outside Raft.

Thanks @greensky00 . All is clear

This may not be within the design intent of nuraft, when forwarding is enabled (nuraft::raft_params::auto_forwarding_ = true), a follower is able to send a message to all cluster members (nuraft::append_entries).
