sunithabeeram edited a comment on issue #4087: Upgrade RoaringBitmap to 0.8.0 URL: https://github.com/apache/incubator-pinot/pull/4087#issuecomment-482725417 I didn't check the backward compatibility part (I am assuming we have generated indexes in atleast one of our tests), however, I was recently looking into the performance of a query against one of our tables; It had a huge IN clause and also had a couple of NOT IN clauses following this format: SELECT count(col) from table where col1 IN "<100+ values>" and col2 NOT IN "<2 values>" and col3 NOT IN "<10+values>" (All columns in the filter clause had inverted-indexes). The base latency of this query was ~450ms. With only updating to roaringbitmap 0.8.0, I see that the latency drops to ~70ms. Thats pretty neat. The mileage across other queries might vary.
