Lambda concurrency limits during Genesys Cloud event spikes

Hey folks,

We’re hitting the ceiling on our Lambda concurrency during peak hours. Genesys Cloud is firing a ton of conversation.update events through EventBridge, and our handler can’t keep up. We get 429s back from the platform when the queue backs up.

Is there a way to batch these requests on the Lambda side, or should we be tuning the provisioned concurrency? Here’s the basic trigger setup:

{
 "source": ["genesys.com"],
 "detail-type": ["Conversation Event"]
}

Any tips on handling the volume?
