- Add links to relevant docs into descriptions for every -kafka.* and -gcp.pubsub.* command-line flags. - Wait until message processing goroutines are stopped before returning from gcppubsub.Stop(). - Prevent from multiple calls to Init() without Stop(). - Drop message if tenantID cannot be parsed properly. - Take into account tenantID for all the supported message formats. - Support gzip-compressed messages for graphite format. - Use exponential backoff sleep when the message cannot be pushed to remote storage systems because of disabled on-disk persistence - https://docs.victoriametrics.com/vmagent.html#disabling-on-disk-persistence - Unblock from sleep as soon as Stop() is called. Previously the sleep could take up to 2 seconds after Stop() is called. - Remove unused globalCtx and initContext from app/vmagent/remotewrite/gcppubsub - Mention Google PubSub support at docs/enterprise.md - Make Google PubSub docs more clear at docs/vmagent.md This is a follow-up for commits 115245924a5f096c5a3383d6cc8e8b6fbd421984 and e6eab781ce42285a6a1750dc01eba6801dd35516 .
