Hi Aman, To attend Drill Developer's Day event, is there any registration process?
Me and Kamesh wanted to present Kafka integration with Drill ( https://github.com/akumarb2010/incubator-drill/tree/master/contrib/storage-kafka & https://issues.apache.org/jira/browse/DRILL-4779 ) Is it possible to provide 15-20 minutes time for this? Thanks & Regards, B Anil Kumar.
