Data Refresh Rate

As the use and complexity of the data analysis tool evolves, some changes have been necessary to ensure the tool continues to have a high level of performance. As a result, the time from when a user changes data in Clarity Human Services to when those changes appear in the data analysis tool may not occur in real-time.

The data refresh rates fall into the following categories:

  • Real-time
  • Persist: Current when initially accessing the data analysis tool, then will persist for the pre-defined amount of time until refreshed
  • Triggered: Refreshed at pre-defined time(s) during the day

The following table identifies the various models and views that use either the Persist or Trigger method of refresh and the rate at which the data is refreshed. For efficiency reasons, all "Training" and "Mig" instances of the data analysis tool only refresh once per week.

Note: Custom fields may be impacted by refresh rates.
