Examples with NoPayload org.apache.cassandra.net.NoPayload used on opensource projects

Example 1 with NoPayload

use of org.apache.cassandra.net.NoPayload in project cassandra by apache.

the class Gossiper method markAlive.

private void markAlive(final InetAddressAndPort addr, final EndpointState localState) {
    localState.markDead();
    Message<NoPayload> echoMessage = Message.out(ECHO_REQ, noPayload);
    logger.trace("Sending ECHO_REQ to {}", addr);
    RequestCallback echoHandler = msg -> {
        // force processing of the echo response onto the gossip stage, as it comes in on the REQUEST_RESPONSE stage
        runInGossipStageBlocking(() -> realMarkAlive(addr, localState));
    };
    MessagingService.instance().sendWithCallback(echoMessage, addr, echoHandler);
    GossiperDiagnostics.markedAlive(this, addr, localState);
}

Example 2 with NoPayload

use of org.apache.cassandra.net.NoPayload in project cassandra by apache.

the class HintsTestUtil method sendHintsAndResponses.

static MockMessagingSpy sendHintsAndResponses(TableMetadata metadata, int noOfHints, int noOfResponses) {
    // create spy for hint messages, but only create responses for noOfResponses hints
    Message<NoPayload> message = Message.internalResponse(HINT_RSP, NoPayload.noPayload);
    MockMessagingSpy spy;
    if (noOfResponses != -1) {
        spy = MockMessagingService.when(verb(HINT_REQ)).respondN(message, noOfResponses);
    } else {
        spy = MockMessagingService.when(verb(HINT_REQ)).respond(message);
    }
    // create and write noOfHints using service
    UUID hostId = StorageService.instance.getLocalHostUUID();
    for (int i = 0; i < noOfHints; i++) {
        long now = Clock.Global.currentTimeMillis();
        DecoratedKey dkey = dk(String.valueOf(i));
        PartitionUpdate.SimpleBuilder builder = PartitionUpdate.simpleBuilder(metadata, dkey).timestamp(now);
        builder.row("column0").add("val", "value0");
        Hint hint = Hint.create(builder.buildAsMutation(), now);
        HintsService.instance.write(hostId, hint);
    }
    return spy;
