Got it. I don't see anything obvious here from a quick look at the metrics.

cgOP•11/23/23, 7:40 PM

As a FYI, I do have the max_message_batch size as 1, because I've found that if it's too high and one worker handles like 10 messages that each make 100 requests, then the queue just dies (somewhat random and silently) due to the max req limit

C

I'm not sure that has anything to do with this however

FWIW I don't see a ton of messages sent here — at least in the underlying Queue broker. is that

Service Temporarily Unavailable

Service Temporarily Unavailable coming as an exception directly from

This is the function that I'm invoking:

export const sendBatchQueueMessage = ({
  batch,
  env,
}: SendBatchQueueMessage) => {
  const ch = chunk(batch, 80);
  return Promise.all(
    ch.map((c) => {
      return env.PROCESS_QUEUE.sendBatch(
        c.map((body) => ({ body: body.message, contentType: 'json' })),
      );
    }),
  );
};

I suspect you're potentially hitting connection limits before you hit the Queues service here because of

Promise.all

Promise.all

Promise.all

Promise.all

especially if you're running this inside your consumer. Something like
```
p-map

p-map
(https://github.com/sindresorhus/p-map) might help to keep the concurrency level down - you can only have 6 simultaneous connections open.

C

cgOP•11/23/23, 7:53 PM

Actually, interestingly, this error seems to be coming from this function:

export const sendQueueMessage = ({ message, env }: SendQueueMessage) => {
  return env.PROCESS_QUEUE.send(message, { contentType: 'json' });
};

export const sendQueueMessage = ({ message, env }: SendQueueMessage) => {
  return env.PROCESS_QUEUE.send(message, { contentType: 'json' });
};

export const sendQueueMessage = ({ message, env }: SendQueueMessage) => {
  return env.PROCESS_QUEUE.send(message, { contentType: 'json' });
};

export const sendQueueMessage = ({ message, env }: SendQueueMessage) => {
  return env.PROCESS_QUEUE.send(message, { contentType: 'json' });
};

Connections will be pending (until they potentially time out). On top of that, you can only make 1000 requests per invocation (e.g. each

send

send

or

sendBatch

sendBatch

counts as one) . An invocation is each call to

queue

queue

queue

queue or

fetch

fetch

.

C

cgOP•11/23/23, 7:59 PM

I'd be surprised if I am hitting the limit, as the log message that I am observing appears in Google Cloud Log Explorer as a result of a

fetch

fetch

that is finalised at the end of the

queue()

queue()

queue() handler

maybe I'm understanding this wrong, but if I am seeing the log message in Logs Explorer as a result of an outbound

queue invocation must be < 1000, or else the log message would never make it

Correct, so we can rule that out.

Well, I must say I'm at a loss here

C

cgOP•11/23/23, 8:44 PM

it might be a bit of a nuclear option, but I could create a new queue?

C

cgOP•11/23/23, 9:01 PM

Well, no, changing to a new Queue did not solve it, still seeing:

 "Queue sendBatch failed: Service Temporarily Unavailable

If you set up the most minimal queue - e.g. identical to the tutorial - do you still see the issue? I want to rule out anything else here.

Heck, just

send(“foo”)

send(“foo”)

send(“foo”)

cgOP•11/23/23, 9:23 PM

I can send messages via the dashbaord and they get received and processed

C

cgOP•11/23/23, 9:24 PM

The Q seems to be working, it's seems like the consumer fails to produce an event

C

cgOP•11/23/23, 9:28 PM

I'll put this at the top of the handleMessage()

C

cgOP•11/23/23, 9:28 PM

  env.logger.info('Sending foo');
  env.PROCESS_QUEUE.send('FOO')
    .then(() => env.logger.info('sent foo'))

  env.logger.info('Sending foo');
  env.PROCESS_QUEUE.send('FOO')

well how about that

some send and some don't

C

cgOP•11/23/23, 9:38 PM

but many don't

cgOP•11/23/23, 9:41 PM

With the error:

 "Queue send failed: Service Temporarily Unavailable"

"Queue send failed: Service Temporarily Unavailable"

 "Queue send failed: Service Temporarily Unavailable"

"Queue send failed: Service Temporarily Unavailable"

Ccg but many don't

Is there a way to delay messages in the queue? i wan't to add them to the queue but consume them in an hour.
