When you send you are blocking the IO thread, so the events don't
actually get put on the wire till the IO thread returns.

Playing around at the moment, and missing something about the threading
situation as it pertains to sending events.

In my ServerSentEventConnectionCallback:

public void connected(ServerSentEventConnection connection, String
lastEventId) {
try {
for (int i = 0; i<10; i++){
connection.send("i="+i);
Thread.sleep(1000);
}
} catch (Exception e) {
throw new RuntimeException(e);
}
}

Sending events, with one second between each.

I’d expect the time between events to be reflected in the browser / client.
However what instead happens is all 10 events arrive within the same
millisecond (nanoseconds apart according to Chrome console time).

So I’m missing something here. But I don’t see anything obvious. For
example, there is nothing like a “flush()” on ServerSentEventConnection that
could be used after each event is sent.

Ideas/guidance?

Thanks!

Ryan
