Github user nickwallen commented on the issue: https://github.com/apache/metron/pull/763 It was hard for me to grok how `ElasticsearchDAO` and `ElasticsearchMetaAlertDAO` differ and how the `ElasticsearchMetaAlertDAO` uses another `IndexDAO` under-the-hood. I think more cow bell (I mean javadocs) would help here. But that is all outside the scope of the work you've done here.
