Pablo Estrada updated BEAM-960:
-------------------------------
Resolution: Fixed
Status: Resolved (was: Open)
> JdbcIO should infer coder when possible (such as via RowMapper)
> ---------------------------------------------------------------
>
> Key: BEAM-960
> URL: https://issues.apache.org/jira/browse/BEAM-960
> Project: Beam
> Issue Type: Improvement
> Components: io-java-jdbc
> Reporter: Kenneth Knowles
> Priority: P3
> Time Spent: 1h 50m
> Remaining Estimate: 0h
>
> 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.
