> JdbcIO should infer coder when possible (such as via RowMapper)
> ---------------------------------------------------------------

> Key: BEAM-960

> Project: Beam
> Issue Type: Bug
> Components: sdk-java-extensions
> Reporter: Kenneth Knowles
> Assignee: Jean-Baptiste Onofré
>
> There are a few ways that we typically do this:
> # Inspect the static args of the class implementing {{RowMapper}} to
> determine the output type, then consult the coder registry. This method is
> more limited and not lambda-friendly.
> # For the a "functional interface" version, like {{RowMapper}} that allows
> setting the output type descriptor.
> # Also provide an abstract class-based version, for example accepting a
> {{SimpleFunction}} that will automatically have a rich output type descriptor.
