Question about event deduplication

[1am]

Hello,

Is there any way to deduplicate events being pushed to the queue? I've found some dedup ocurrences but I'm not yet clear if this can be used from the client side? I have a protection mechanism for double task execution for same inputs but am looking if it could be handled on the Hatchet level when adding items.

Best regards

Hi @1am, this can be set from the client side by added a key called dedupe to the additional metadata of the workflow, and then setting the value to the field you'd like to dedupe on.

We're working on exposing this as a better deduplication API (including a count for the # of occurrences) using expression-based syntax parsing for deduplication keys. Will share an update here when we tackle that.

Thank you @abelanger5 This sounds great but I can't seem to find how to specify dedup in metadata of the workflow when using RegisterWorkflow. I've started with similar approach as in in examples/simple/main.go Could you point me to how to call createNewWorkflowRun which seems to deal with dedupe key?
