> [JsonToRow|https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/transforms/JsonToRow.java]
> supports only strict schema matching, so it expects all the fields that are
> declared by the schema to be present in the input JSON data. If the field is
> missing, [it
> crashes|https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/util/RowJsonDeserializer.java#L114-L117].
> In practice it is useful to default to null is such cases. We should make it
> configurable in Beam Java SDK at least, and probably in Beam SQL (in Pubsub
> Json TableProvider) as well.
