Question

A developer is building an order-processing microservice that receives up to 8,000 messages per second. Each message represents an independent event, and the downstream consumer is already designed to be idempotent. The team wants the simplest, highest-throughput queue that keeps costs low. Which Amazon SQS configuration best fits these requirements?

Accepted Answer

Answer

Use a FIFO queue with a single message group ID to guarantee ordering across all orders.

Answer

Use a FIFO queue with high-throughput mode enabled to exceed 3,000 messages per second.

Answer

Use a standard queue with content-based deduplication enabled to prevent duplicate messages.
