Improve Java 4 Cassandra

"We use Apache Cassandra, which recommends nodes with only a terabyte of data; but we’re pushing nodes with 10 TBs of data densities and still achieving the performance we need. ....... In short, we’re achieving unobtainable technical feats with Azul Zing that you can’t achieve using plain vanilla Java. And this performance translates into huge infrastructure savings and simplification by having less servers. With Azul, we were able to reduce our front-end server footprint by more than 30%, which is hundreds of servers, and our database server footprint by about 50%" (Ariel Pizetsky, VP of IT, Taboola)
