 * **Backing indices:** A TSDS uses [time-bound indices](/manage-data/data-store/data-streams/time-bound-tsds.md) to store data from the same time period in the same backing index.
 * **Dimension-based routing:** The routing logic uses dimension fields to map all data points of a time series to the same shard, improving storage efficiency and query performance. Duplicate data points are rejected.
 * **Sorting:** A TSDS uses internal [index sorting](elasticsearch://reference/elasticsearch/index-settings/sorting.md) to order shard segments by `_tsid` and `@timestamp`, for better compression. Time series data streams do not use `index.sort.*` settings.
+* **Source field:** A TSDS uses [synthetic `_source`](elasticsearch://reference/elasticsearch/mapping-reference/mapping-source-field.md#synthetic-source), and as a result is subject to some [restrictions](elasticsearch://reference/elasticsearch/mapping-reference/mapping-source-field.md#synthetic-source-restrictions) and [modifications](elasticsearch://reference/elasticsearch/mapping-reference/mapping-source-field.md#synthetic-source-modifications) applied to the `_source` field.

-You can use the {{esql}} [`TS` command](elasticsearch://reference/query-languages/esql/commands/ts.md) (in technical preview) to query time series data streams. The `TS` command is optimized for time series data. It also enables the use of aggregation functions that efficiently process metrics per time series, before aggregating results.
