> Currently, the {{TypeInformations}} must be serializable because they are shipped with UDFs of the Table API to the TMs. There the Table API code is generated and compiled. By generating the code on the client and shipping the code as strings, we could get rid of this dependency. As a consequence, the {{TypeInformations}} can be non-serializable again, as they were intended to be.
> Maybe [~aljoscha] can provide some more implementation details here.
