Using MySQL as a NoSQL - A story for exceeding 750,000 qps on a commodity server
UPDATE: Oracle officially released memcached daemon plugin that talks with InnoDB. I'm glad to see that NoSQL+MySQL has become an official solution. It's still preview release but will be very promising. Let's try it to make it better! Most of high scale web applications use MySQL + memcached. Many of them use also NoSQL like TokyoCabinet/Tyrant. In some cases people have dropped MySQL and have sh

Java running faster than C
Note: A lot of people seem to be taking this post to be the "Ultimate C vs Java shootout". It's not. Performance is a very complex topic. My only real point is this: Java (which used to be slow) has reached the class of "fast languages". For the majority of applications, speed is no longer a valid excuse for using C++ instead of Java. I just saw this page comparing the performance of several langu
