> When the source is a protobuf3 message, and the target file is Parquet, all the default values are stored in the output parquet as `{{null`}} instead of the actual type's default value.
>  For example, if the field is of type `int32`, `double` or `enum` and it hasn't been set, the parquet value is `{{null`}} instead of `0`. When the field's type is a `string` that hasn't been set, the parquet value is {{`null`}} instead of an empty string.
