--------------------------------------
Colleagues any updates on this?
> Add support for custom CSV field parsers
> ----------------------------------------
>
> Key: FLINK-2435
> URL: https://issues.apache.org/jira/browse/FLINK-2435
> Project: Flink
> Issue Type: New Feature
> Components: DataSet API
> Affects Versions: 0.10.0
> Reporter: Fabian Hueske
> Assignee: Dmitrii Kober
> Priority: Minor
> Fix For: 1.0.0
>
>
> The {{CSVInputFormats}} have only {{FieldParsers}} for Java's primitive types
> (byte, short, int, long, float, double, boolean, String).
> It would be good to add support for CSV field parsers for custom data types
> which can be registered in a {{CSVReader}}.
> We could offer two interfaces for field parsers.
> 1. The regular low-level {{FieldParser}} which operates on a byte array and
> offsets.
> 2. A {{StringFieldParser}} which operates on a String that has been extracted
> by a {{StringParser}} before. This interface will be easier to implement but
> less efficient.
