What happened?

pipeline:
type: chain
transforms:
- type: Create
config:
elements:
- {sdk: MapReduce, year: 2004}
- {sdk: Flume}
- {sdk: MillWheel, year: 2008}

in beam yaml, in an example as above, the default schema that the parser returns removes any fields in rows that do not contain values for it, like in this case the schema has two parameters at first but once it reads the second element does not contain year as a parameter, it assumes it is not necessary and then it drops the parameter in the overall schema

another issue is that byte strings are not definable in beam yaml, maybe due to an external parsing issue,
