问题 We are designing out our listening side of Google PubSub and will be using Google Functions for this. There are two choices, push and a backend function. Push using Http and will push messages to the function. backend function uses triggering to invoke the function. Where we are having trouble is deciding which approach may be better for our application. We have not been able to find a list of differences between these two methods within the Google documentation. Some things we have noticed

问题 I have a Google Pub/Sub project and created a topic and a simple subscription. However, when specifying a URL for push, I keep getting the error below.

问题 Within the same application I send different message types that have a completely different format and that are totally unrelated. What is the best practice to tackle this problem? I see two different approaches here : Filter at application level, which means I receive all messages on the same puller (same subscription) Create a new subscription, this means the application will have two pullers running (one for each message type) 回答1: You anwsered your question with 2. point. If the message

问题 I have some sample code that batches events by a fixed window. I would like to combine these events that are in the fixed window - into a single string of messages. Then publish the combined packed message. Here is the code: final PCollection<String> filteredEvents = ind.apply(FilterEvents.STEP_NAME, ParDo.of(new FilterEvents())); final PCollection<String> windowEvents = filteredEvents.apply(Window.<String>into(FixedWindows.of(Duration.standardSeconds(1)))); final PCollection<String>

问题 Let's say a code running in Region A publishes a message. Can cloud function in region B and C subscribe for such events? 回答1: In standard, YES. Pubsub is a global service. If the publisher and the subscriber are in the same region, there is no reason the message change region. But in cross region, the message is forwarded to the subscriber region and then consumed. You don't see this mechanism, it's automatic and managed by PubSub However, if you have legal constrains, you can limit the
