Description

private CompletableFuture<Void> finish(boolean commit) {
    ...
    for (Map.Entry<NetworkAddress, Set<String>> entry : tmp.entrySet()) {
        boolean local = address.equals(entry.getKey());

        futs[i++] = local ? commit ? txManager.commitAsync(timestamp) : txManager.rollbackAsync(timestamp) :
                txManager.finishRemote(entry.getKey(), timestamp, commit, entry.getValue());
    }

 

If local is false txManager.finishRemote() will be called that’ll be replicate txState over all raft group members.However if local is true we will only change txState locally.
