Github user cestella commented on the issue: https://github.com/apache/metron/pull/934 Chiming in late. I agree that we should not have an explicit dependency on an indexing Mpack, even one not of our own construction. I think people will have a lot of different ways to install solr and Metron's mpack should just be configured to point to an existing solr instance. I would generally be in favor of adding support for: * solr.commitPerBatch * solr.commit.waitSearcher * solr.commit.waitFlush * solr.commit.soft * solr.collection * solr.http.config but sensible defaults are chosen there and people can adjust them in the global config, so I think they can wait for a follow-on. Some of them may be problematic to encode in a UI (solr.http.config is a map, for instance), but most of them would be pretty trivial. Frankly, I'm a bit hesitant to give people the ability to screw with transactions details easily.
