Working with Live Mode and Historical Playback
Live mode and historical playback allow you to get the most from data stores that support playback. Live mode refreshes fields that are indexed as playable to update the data on your visualizations. In live mode, your data plays forever without an end date. Similarly, historical playback shows the historical record of fields within the data. Playback can show up to the last moment before the current period in your data. The only difference between live mode and historical playback is the time range that is selected.
Live mode and historical playback require an index or partition field. If the data source in question does not support indexing or partitioning, then live mode and historical playback are not available.
Your data store must support indexing or partitioning. For most data stores, indexing is the norm.
