Pretty sure there's no way to do this but would be great to reach out to see if anyone else has any ideas. What I'm trying to do is this: I have 2 microservices hosted on Google Cloud Platform as cloud functions My first microservices does stuff and fires a PubSub message with topic [x] I'd like to set my second microservice up as a push subscriber to the topic [x]. I know I can do this by deploying the 2nd cloud function with a subscription trigger but I don't want to do this as there's no decent way to acknowledge/reject the message (see this post: Google Cloud Functions to only Ack Pub/Sub

We are using a cloud function triggered by Pub/Sub to ensure delivery of an e-mail. Sometimes the e-mail service takes a long time to respond and our cloud function terminates before we get an error back. Since the message has already been acknowledged our e-mail gets lost. The cloud function appears to be sending an ACK the Pub/Sub message automatically when we are called. Is there a way to delay the ACK until the successful completion of our code? Alternatively is there a way to catch timeouts and requeue the message for delivery? Something else we could try? I heard from Google support that

I'm using node.js to create an app that gets a PUSH from Gmail each time an email is received, checks it against a third party database in a CRM and creates a new field in the CRM if the e-mail is contained there. I'm having trouble using Google's new Cloud Pub/Sub, which seems to be the only way to get push from Gmail without constant polling. I've gone through the instructions here: https://cloud.google.com/pubsub/prereqs but I don't understand how exactly this is supposed to work from an app on my desktop. It seems that pub/sub can connect to a verified domain, but I can't get it to connect

Architecture: We have an architecture using 2 pubsub topic/subscription pairs: Topic T1 is triggered by a cronjob periodically (every 5 minutes for example). Subscription S1 is the trigger for our cloud function. Topic T2 serves as a queue for background jobs that are published by one of our services. Subscription S2 is read by the cloud function on each execution to service the queued background jobs. This allows us to control the frequency the background jobs are serviced independent of when they are added to the queue. The cloud function (triggered by S1 ) reads messages from S2 by pulling

I am trying write Google PubSub messages to Google Cloud Storage using Google Cloud Dataflow. I know that TextIO/AvroIO do not support streaming pipelines. However, I read in [1] that it is possible to write to GCS in a streaming pipeline from a ParDo/DoFn in a comment by the author. I constructed a pipeline by following their article as closely as I could. I was aiming for this behaviour: Messages written out in a batches of up to 100 to objects in GCS (one per window pane) under a path that corresponds to the time the message was published in dataflow-requests/[isodate-time]/[paneIndex] . I
