INFRA-212Drafting memotech-choice
Which queue for settlement webhooks — SQS or Temporal?
The new settlement webhook fanout needs at-least-once delivery and visibility into stuck retries. Two reasonable options on the table.

SQS gives us at-least-once + DLQ in 3 hours and zero monthly cost at our volume.
Temporal is the better long-term home for workflows but is a 2-week ramp for the team.
Recommendation lean: SQS now, revisit when we hit 50 workflows.
Options
SQS · ships in 3h
Already in use for emails
cost: $0/mo at volume
Temporal · 2w ramp
Workflow-native; better long-term ceiling
cost: Onboarding + new infra to operate
