A bully on the internet today claimed that OSS metaflow doesn't support event-based triggering. Is that true? For example, if I use AWS Batch + Step Functions as the underlying orchestrator, can I use aws event bridge and boto3 to trigger flow runs?

they have probably seen in the docs that `@trigger` etc are only supported on the K8s stack today

You can certainly use Event Bridge to trigger executions on SFN, as well as <https://docs.metaflow.org/api/deployer#StepFunctionsDeployedFlow.trigger|the new >`Deployer`<https://docs.metaflow.org/api/deployer#StepFunctionsDeployedFlow.trigger| API >that the bully might not be aware of, since it's a newer feature :slightly_smiling_face:

so <https://m.xkcd.com/386/|as usual in the interweb>, they are half-right and half-wrong
