3. nagging dedup that needs to be taken care by yourself. What you get now: • One bus across every account in the org, wired through RAM • Filter, targets, retries and DLQ in one subscriber object • EventGroupId for ordered delivery, opt in per subscriber

• Sync Lambda invocation, no SQS buffer in front of it • Content-based dedup, collapses matches inside 5 minutes • JSONata to reshape, Avro and Protobuf deserialized 10k subs per bus! Nice 💛 btw pricing changes here too: Publishers pay for events ingested, subscribers for events delivered
