This is a hack to handle weird schemas like {type: object, string}. If a stream's top-level schema looks like this, we still want to be able to extract the object properties (i.e. treat it as though the string option didn't exist).

chooseType

fun chooseType(): AirbyteType

This matches legacy behavior. Some destinations handle legacy unions by choosing the "best" type from amongst the options. This is... not great, but it would be painful to change.

collectUnknownPaths

fun AirbyteType.collectUnknownPaths(currentPath: String = ""): Set<String>

computeUnknownColumnChanges

fun AirbyteType.computeUnknownColumnChanges(): List<Meta.Change>

This function exists so that our tests can easily mock a DestinationStream, while still getting a real value for unknownColumnChanges.

withAirbyteMeta

fun AirbyteType.withAirbyteMeta(flatten: Boolean = false): ObjectType
