Replace Field Action
Provided by: "Apache Software Foundation"
Support Level for this Kamelet is: "Preview"
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.
