Cassandra Rewritten In C++, Ten Times Faster
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?
But, but... Java is enterprisey!
They also boosted performance by never freeing memory, too!
If you post it, they will read.
Oracle has just launched a new series of patent infringement lawsuits. Oracle allegations include reverse engineering Java to improve the speed of applications like Cassandra, benchmarking Java without permission. They are seeking an immediate cease and desist order, in addition to immediate financial relief for sustaining PPS (More commonly known as Poopy Pants Syndrome.).

Well, let's see. % means its a conversion code, l means the converted quantity is a long, i means its an integer, so a long integer, but e means it's a float to be converted to exponential notation. But it was supposed to be an integer. Does not compute.
I will only use MongoDB because it is web scale.
