<alias> -
(Required, string) Name of the index alias to convert to a data stream. The alias must meet the following criteria:
- The alias must have a write index.
-
All indices for the alias have a
@timestampfield mapping of adateordate_nanosfield type. - The alias must not have any filters.
- The alias must not use custom routing.
If successful, the request removes the alias and creates a data stream with the same name. The alias’s indices become hidden backing indices for the stream. The alias’s write index becomes the stream’s write index.
