Why Unique Indexes are Bad | Architects Zone

Why Unique Indexes are Bad | Architects Zone | Programming | Scoop.it

Before creating a unique index in TokuMX or TokuDB, ask yourself, “does my application really depend on the database enforcing uniqueness of this key?” If the answer is ANYTHING other than yes, do not declare the index to be unique. Why? Because unique indexes may kill your write performance. In this post, I’ll explain why.

Unique indexes are a strange beast. They have no impact on standard databases that use B-Trees, such as MongoDB and MySQL, but may be horribly painful for databases that use write optimized data structures, like TokuMX’s Fractal Tree(R) indexes. How? They essentially drag the Fractal Tree index down to the B-Tree’s level of performance.

Caching In: Understand, Measure and Use your CPU Cache More Effectively | Javalobby

Caching In: Understand, Measure and Use your CPU Cache More Effectively | Javalobby | Programming | Scoop.it

Modern computationally intensive tasks are rarely bottlenecked by the absolute performance of your processor cores. The real bottleneck in 2013 is getting data out of memory. CPU caches are designed to alleviate the difference in performance between CPU core clock speed and main memory clock speed, but developers rarely understand how this interaction works or how to measure or tune their application accordingly. This session aims to address this by:

Describing how CPU caches work in the latest Intel hardwareShowing what and how to measure in order to understand the caching behavior of softwareGiving examples of how this affects Java program performance and what can be done to address poor cache utilization
