> Originally SchemaCoder and RowCoder relied on including serialized java classes and functions to support logical types, but the [portable schema representation|https://s.apache.org/beam-schema] only includes a URN for a logical type. We will need to be able to re-construct logical types given just a URN, presumably by creating some sort of logical type registry indexed by URN.
