DLQ and retry policy

[assaf]

https://docs.aws.amazon.com/lambda/latest/operatorguide/sqs-retries.html

export const config = {
  retries: 5;
  delay: "1m";
};

• Do we use "retries" or "attempts" (3 retries = 4 attempts to process)?
• What's a good default? 5?
• Do we allow changing the delay between retries?
• Default delay between retries? 30s -> 1m -> 5m (x3)
• How do we manage DLQ (separate issue)?
