> Currently, transform module supports rarely-used "partial filtering" feature:
> {code:java}
> transform:
> - source-table: mydb.web_order
> projection: id, order_id
> filter: UPPER(province) = 'SHANGHAI'
> description: classification mapping example
> - source-table: mydb.web_order
> projection: order_id as id, id as order_id
> filter: UPPER(province) = 'BEIJING'
> description: classification mapping example {code}
> This causes unnecessary type consistency constraints. Deprecating such
> feature in the next major release should be acceptable.
