The DICE Quality Testing (QT) tool is a load testing system for Storm-based applications. QT consists of two modules:
- QT-GEN: a tool to generate input stream data similar, but nevertheless non-identical, to the real stream data supplied to it.
- QT-LIB: a Java library to inject custom spouts in Apache Storm that are able to replay externally provided traces (or random data) at user-specified rates and data volumes.
A high-level overview of the QT methodology is given in the figure below:
QT-GEN can be used to generate workloads either from JSON files or from Apache Storm logs. The output is saved in a JSON file that is fed to custom spouts provided by QT-LIB for load-testing of an Apache Storm application.
