Java Pojo attribute to column mapping

[dhanan-np]

It would be great if we could get a feature like OpenCSV where we can directly bind the csv columns to the Attributes of Java Pojo

Hi - thanks for the suggestion. For certain use cases, column mapping to a POJO is a great idea. I believe this feature could be built as a wrapper around the existing interfaces. It may be best to do the mapping "on the fly" so the user doesn't pay the cost of the POJO until they read that row.

Given that deephaven-csv parses and presents the results as column-oriented structures, I'm curious what the performance would be to map back into a POJO per row. I'm guessing it would still be faster than row-oriented approaches that other CSV parsers use, but that is something we'd need to benchmark.

If this is something you are interested in providing a PR for, we're happy to provide further guidance!
