Chapter 58. Replace Field Action
Replace field with a different key in the message in transit.
- The required parameter 'renames' is a comma-separated list of colon-delimited renaming pairs like for example 'foo:bar,abc:xyz' and it represents the field rename mappings.
- The optional parameter 'enabled' represents the fields to include. If specified, only the named fields will be included in the resulting message.
- The optional parameter 'disabled' represents the fields to exclude. If specified, the listed fields will be excluded from the resulting message. This takes precedence over the 'enabled' parameter.
- The default value of 'enabled' parameter is 'all', so all the fields of the payload will be included.
- The default value of 'disabled' parameter is 'none', so no fields of the payload will be excluded.
