Preview a transform Generally available; Added in 7.2.0

POST /_transform/{transform_id}/_preview

Generates a preview of the results that you will get when you create a transform with the same configuration.

It returns a maximum of 100 results. The calculations are based on all the current data in the source index. It also generates a list of mappings and settings for the destination index. These values are determined based on the field types of the source index and the transform aggregations. ##Required authorization

  • Index privileges: read,view_index_metadata* Cluster privileges: manage_transform

            • limit number | string

              The maximum number of fields in an index. Field and object mappings, as well as field aliases count towards this limit. The limit is in place to prevent mappings and searches from becoming too large. Higher values can lead to performance degradations and memory issues, especially in clusters with a high load or few resources.

            • ignore_dynamic_beyond_limit boolean | string

              This setting determines what happens when a dynamically mapped field would exceed the total fields limit. When set to false (the default), the index request of the document that tries to add a dynamic field to the mapping will fail with the message Limit of total fields [X] has been exceeded. When set to true, the index request will not fail. Instead, fields that would exceed the limit are not added to the mapping, similar to dynamic: false. The fields that were not added to the mapping will be added to the _ignored field.
