PutDatbaseRecord requires that the Statement Type be defined as a property or a FlowFile attribute. This means that if a FlowFile has many records, it must be split apart into individual Records if there is more than 1 type of statement needed per FlowFile.
It also assumes that the data to be inserted/updated/deleted/etc is the full record. However, it's common to have some wrapper around the actual data, as is the case with a tool like Debezium, which includes an Operation Type, a 'before' snapshot and an 'after' snapshot. To accommodate this, we should allow Record-friendly methods for specifying the path to the data and the operation type.
