Topics[edit]

  • Standard Topics

Standard topics can be used in many scenarios, as long as your application can process messages that arrive more than once and out of order, for example: fanning out messages to media encoding, fraud detection, tax calculation, search index, and critical alerting applications.

  • Maximum throughput: Standard topics support a nearly unlimited number of messages per second.
  • Best-effort ordering: Occasionally, messages might be delivered in an order different from which they were published.
  • FIFO Topics, designed to enhance messaging between applications when the order of operations and events is critical, or where duplicates can't be tolerated, for example: fanning out messages to bank transaction logging, stock monitoring, flight tracking, inventory management, and price update applications.
  • High throughput: FIFO Topics support up to 3,000 messages per second or 10 MB per second per FIFO topic (whichever comes first).
  • Strict ordering: The order in which messages are published and delivered is strictly preserved (i.e. first-in-first-out).
