      Work Description: charithe commented on issue #8725: [BEAM-6674] Add 
schema support to JdbcIO read
URL: https://github.com/apache/beam/pull/8725#issuecomment-501180367
 
 
   If the user provides their own row mapper to convert the resultset to some 
type `T`, then I don't see why the schema of `T` should be compatible with the 
inferred schema of the resultset. For example, the query might have separate 
fields to hold `first_name` and `last_name` but during the mapping the user 
might choose to combine those two fields to create a single field named 
`full_name`.
