> Add BigDecimal and BigInteger as Basic types
> --------------------------------------------
>
> Key: FLINK-3786
> URL: https://issues.apache.org/jira/browse/FLINK-3786
> Project: Flink
> Issue Type: New Feature
> Components: Core
> Reporter: Timo Walther
> Assignee: Timo Walther
>
> We already had the discussion on the mailing list some months ago about
> adding BigDecimal and BigInteger as basic types.
> Especially for business or scientific applications it
> makes sense to support the BigInteger and BigDecimal types natively. In
> my opinion they are as important as Date or Void and should be added as
> BasicTypes. The Table API would also benefit from it.
