Druid Java Client

Hi,

Can someone point out to a Java client for creating druid queries ? I searched on the net and came across this one: https://github.com/apache/incubator-druid/tree/master/processing/src/main/java/io/druid/query

This looks fine. May I know if this is stable and okay to be used?

You can also take a look at https://github.com/zapr-oss/druidry

Thanks for your reply
