Google Apps that use Google pub/sub services

[mo...@sonicskyapps.com]

I see that APIs of some of the Google Apps such as GMAIL use Google pub/sub service while the Reports API do not use the same for notification. The questions I have are

a) why?

b) what are implications? Should the GMAIL api user who uses notification should also subscribe to the Google pub/sub service (or Google cloud platform) OR Google Apps for Work subscription is good?

Hey mo...@sonicskyapps.com,

I'm quite sure that I'm unable to speak for the engineers behind various services why it is that they have or haven't taken which architecture decisions. I'm also unsure exactly what implications, if any, we can draw here. However, I can assist by asking what it is that you're looking to accomplish, and wondering whether there's anything I can help answer directly related to your needs?

Regards,

Nick
