We started a POC of Sparkling water and realized they are internally using the duke library. Nor sure what features of Duke Library H2o.

Duke allows to use custom comparators? Does h2o exposes this feature ?

I have gone through the source code and the only reference i see is during the H2oContext Initialization they are making sure the Duke Library Comparator is loaded. How ever i didn't see any other places where they are actually using the comparators.

Thanks

  • SW (or H2O) does not expose custom comparators. You can use comparators that are built-in Duke in PySparkling and/or RSparkling. Documentation for PySparkling: https://github.com/h2oai/h2o-3/blob/master/h2o-py/h2o/frame.py#L2200 This feature is not directly exposed in the Scala API as of now. – Michal Kurka Jan 30 '18 at 23:08
  • Thanks for quick response. Are there any plans of exposing this feature in scala API in the near future ? Could you pls let us know. – Sateesh K Jan 31 '18 at 05:18
  • It can be added, please make a feature request in our JIRA: https://0xdata.atlassian.net/ – Michal Kurka Feb 01 '18 at 23:54
