Google Cloud Pub/Sub : Qwik Start – Outil de ligne de commandeGo to Lab
Notes that the message order is not guaranteed even if we have single subscriber would be a nice point to put it out there. Also observed that when publisher finished publishing four message and subscriber started reading with limit 4, only three were read and I had to re-run the read to get the last message. Telling me that there is latency in the pub/sub even though publisher gives me a message ID!
A very informative introduction to the google command line
