I just attended the talk by Julian Hyde at Apache Big Data. The presentation was similar to the one at the Hadoop Summit here:
http://www.slideshare.net/julianhyde/querying-the-internet -of-things-streaming-sql-on-kafkasamza-and-stormtrident We discussed SQL at various occasions, Calcite integration seems the way to go. My current idea is that a SQL query can be applied on top of a base application or used to define a SubDAG, and introduce additional operators. It also plays into the interactive query capability (app data). There is an existing JIRA and maybe it is time to get to the next level of discussion: https://issues.apache.org/jira/browse/APEXMALHAR-1818 Julian has expressed interest to work with us on this. Thanks, Thomas
