Configuration
A transformation chain will be configured at the connector-level. The order of transformations is defined by the transforms
config which represents a list of aliases. An alias in transforms
implies that some additional keys are configurable:
- transforms.$alias.type
– fully qualified class name for the transformation
- transforms.$alias.*
– all other keys as defined in Transformation.config()
are embedded with this prefix
