Examples with RpcClient org.apache.ignite.raft.jraft.rpc.RpcClient used on opensource projects

Example 1 with RpcClient

use of org.apache.ignite.raft.jraft.rpc.RpcClient in project ignite-3 by apache.

the class AbstractClientService method connectAsync.

@Override
public CompletableFuture<Boolean> connectAsync(Endpoint endpoint) {
    final RpcClient rc = this.rpcClient;
    if (rc == null) {
        throw new IllegalStateException("Client service is uninitialized.");
    }
    // Remote node is alive and pinged, safe to continue.
    if (readyAddresses.contains(endpoint.toString())) {
        return CompletableFuture.completedFuture(true);
    }
    final RpcRequests.PingRequest req = rpcOptions.getRaftMessagesFactory().pingRequest().sendTimestamp(System.currentTimeMillis()).build();
    CompletableFuture<Message> fut = invokeWithDone(endpoint, req, null, null, rpcOptions.getRpcConnectTimeoutMs(), rpcExecutor);
    return fut.thenApply(msg -> {
        ErrorResponse resp = (ErrorResponse) msg;
        if (resp != null && resp.errorCode() == 0) {
            readyAddresses.add(endpoint.toString());
            return true;
        } else {
