-In a TSDS, {es} uses dimensions to
-generate the document `_id` and <<tsid,`_tsid`>> values. The resulting `_id` is
-always a short encoded hash. To prevent the `_tsid` value from being overly
-large, {es} limits the number of dimensions for an index using the
-<<index-mapping-dimension-fields-limit,`index.mapping.dimension_fields.limit`>>
-index setting. While you can increase this limit, the resulting document `_tsid`
-value can't exceed 32KB. Additionally the field name of a dimension cannot be
-longer than 512 bytes and the each dimension value can't exceed 1kb.
