Limitations

  • In-memory only — Jobs live in RAM (bounded by available memory)
  • No historical replay — Acknowledged jobs are removed
  • Leader-dependent writes — All submissions go through the current leader
  • Bounded capacity — Configurable topic queue size
  • Not a streaming platform — Use Kafka for large-scale persistent logs

Cue is ideal for reliable job dispatch with retries, not for event streaming or long-term storage.
