Cassandra Rewritten In C++, Ten Times Faster

Posted by samzenpus on from the greased-lightning dept.

urdak writes: At Cassandra Summit opening today, Avi Kivity and Dor Laor (who had previously written KVM and OSv) announced ScyllaDB — an open-source C++ rewrite of Cassandra, the popular NoSQL database. ScyllaDB claims to achieve a whopping 10 times more throughput per node than the original Java code, with sub-millisecond 99%ile latency. They even measured 1 million transactions per second on a single node. The performance of the new code is attributed to writing it in Seastar — a C++ framework for writing complex asynchronous applications with optimal performance on modern hardware.

    Because it was written in Seastar

    That is a lie!

    I think they mean the C++ port is 10X SLOWER than Java.

    Java is faster than C,C++ everyone knows that!

    Maybe if they ran the code on a java interpreter, written in java, running on a java interpreter...

    More recursive use of java == more speed!

    Why slow a system down with all that C++ bloatware?
