Work Description: reuvenlax commented on pull request #10151: [BEAM-7116] Remove use of KV in Schema transforms
URL: https://github.com/apache/beam/pull/10151
Beam's KV type has no schema and due to special casing of KvCoder in Beam it is difficult to give it one. Here we modify the Beam schema transforms that return PCollection<KV> to instead return PCollection<Row> where the Row contains key and value fields. This is possible now that we support large iterables in schemas.

> Instead of returning KV objects, we should return a Schema with two fields. The Convert transform should be able to convert these to KV objects.
