Hi All,
Wondering if it is possible to filter pub / sub messages by custom metadata fields on files for cloud storage notifications?
Yes it’s possible to filter pub / sub messages, but only from their attributes and not the data in the message, when you receive messages from a subscription with a filter, you only receive the messages that match the filter. The Pub/Sub service automatically acknowledges the messages that don’t match the filter.
You can read more about this in the documentation i’m sharing with you.
