 Even though each salt bucket is updated approximately once per year, individual bucket updates are spread over the year. Approximately 1/365th of all salt buckets are rotated daily. Based on this, we recommend checking salt bucket rotation regularly, on a cadence that aligns with your audience refreshes. For example, if you refresh weekly, check for salt bucket updates weekly.
