(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 @timestamp field mapping of a date or date_nanos field 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.
