> Need to add new methods which should convert a value of StructType to a schema in DDL format . It should be possible to use the former string in new table creation by just copy-pasting of new method results. The existing methods simpleString(), catalogString() and sql() put ':' between top level field name and its type, and wrap by the *struct* word
> {code}
> ds.schema.catalogString
> struct<metaData:struct<eventId:string ...
> {code}
> Output of new method should be
> {code}
> metaData struct<eventId:string ...
> {code}
