Isn’t Lucene already a household name?

I didn't realize Lucene used their own flavor of roaring bitmaps! Super Cool. I certainly think of search when it comes to Lucene, where as the cited material from Vikram & FeatureBase are targeting more general analytics.

Lucene is fast, but probably can't handle analytical type questions on massive amounts of data as fast as a pure binary index can. I could be wrong about that though. I do know Solr has it because Lucene does...

Elasticsearch (another household name) is built on Lucene too, so I wouldn’t count it out.

Probably not, first thought I had was Lucerne dairy products.

Not sure I understand your point. Can you clarify some?

Lucene uses roaring bitmaps for filters.

Sure, I completely get it. However, does that mean bitmaps have been fully explored? For example, OLAP is only growing as a market as the need for realtime analysis on the most fresh data. I mean, we never going to have 'less' data nor are we ever going to seek results 'slower'. Where I am going with this, utilizing technologies like bitmaps in OLAP services is an area I believe will see continued growth. While Lucene is a known commodity, I think we can agree it hasn't solved the sector, right?
