I see thanks

You can invoke a Lambda however you'd like. Event-Bridge (formerly CloudWatch Events) is a fine option for a scheduled "cron" task.

@U02CV2P4J6S If you're still having trouble with this, you can follow the https://github.com/Datomic/ion-starter project, specifically, the section on https://github.com/Datomic/ion-starter/blob/master/src/datomic/ion/starter/lambdas.clj for inspiration.

@U0CJ19XAM hm. Do you know if the event bridge has the correct permissions and such by default? I guess I'll try making a simple one work

Datomic doesn't give any AWS services permissions to invoke Lambda Ions by default.

Ah alright. Then I know I have to grant the permission/role somehow

I'd follow https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-run-lambda-schedule.html but use the Lambda Ion instead of the javascript one they show you how to make. Specifically, you need to do the part (that I can't link to ) that starts with the phrase To grant the EventBridge service principal....

thanks a lot that was the thing
