If the {es} {security-features} are enabled, you must have the following
|
|
built-in roles and privileges:
|
|
|
|
* `manage_transform`
|
|
* source index: `view_index_metadata`
|
|
|
|
For more information, see <<security-privileges>> and <<built-in-roles>>.

When you start a {transform}, it creates the destination index if it
|
|
does not already exist. The `number_of_shards` is set to `1` and the
|
|
`auto_expand_replicas` is set to `0-1`.
|
|
|
|
The {transform} deduces the mapping definitions from the source indices. For
|
|
scripted fields, it uses <<dynamic-mapping,dynamic mappings>>. If a field in the
|
|
destination index is created by `scripted_metric` or `bucket_script`
|
|
aggregations, the {transform} uses dynamic mappings unless a template exists or
|
|
the destination index already exists. Mapping definitions in the destination
|
|
index take precedence over dynamic mappings and templates.
|
|
|
|
When the {transform} starts, a series of validations occur to ensure
|
|
its success. If you deferred validation when you created the
|
|
{transform}, they occur when you start the {transform}--with the
|
|
exception of privilege checks. When {es} {security-features} are enabled, the
|
|
{transform} remembers which roles the user that created it had at the
|
|
time of creation and uses those same roles. If those roles do not have the
|
|
required privileges on the source and destination indices, the
|
|
{transform} fails when it attempts unauthorized operations.
