Occurrent 0.7.2 is now available. It’s a very small release that really allows deploying Occurrent subscriptions to Atlas free tier.


  • When running MongoDB subscriptions on services like Atlas, it’s not possible to get the current time (global subscription position) when starting a new subscription since access is denied. If this happens then the subscription will start at the “current time” instead (StartAt.now()). There’s a catch however! If processing the very first event fails and the application is restarted, then the event cannot be retried. If this is major concern, consider upgrading your MongoDB server to a non-shared environment.
