-| Compute Concurrency                           | 5 concurrent audiences        | Segment computes five new audiences or computed traits at a time. Once the limit is reached, Segment queues additional audience computations until one of the five audiences finishes computing. |
-| Compute Throughput                            | 10000 computations per second | Computations include any Track or Identify call that triggers an audience or computed trait re-computation. Once the limit is reached, Segment may slow audience processing.                     |
-| Events Lookback History                       | 3 years                       | The period of time for which Segment stores audience and computed traits computation events.                                                                                                     |
-| Real-time to batch destination sync frequency | 2-3 hours                     | The frequency with which Segment syncs real-time audiences to batch destinations.                                                                                                                |

-| Event Properties (Computed Traits)            | 10,000                        | For Computed Traits that exceed this limit, Segment will not persist any new Event Properties and will drop new trait keys and corresponding values.                                             |
