Release version 4.0.0 · dice-group/IGUANA

Version 4.0.0 is a complete rework and aims to improve the stability and accuracy of benchmark results.

Most Significant Changes

🚄 More consistent & reliable results By using GraalVM to precompile the binaries IGUANA shows persistent performance from the start. Before, the warmup and iterative JIT-compilation of the JVM lead to handling earlier queries slower than later queries. This could be observed in increasing triplestore performance being reported over the course of an evaluation.
👑 Rich result formats The results are now available in RDF and CSV making it easy to analize them the tools you prefer. Issues in the ontology were resolved.
😤 Even more stress By removing synchronization points between IGUANA's clients it is now able to put triplestores under even more stress when requesting with multiple clients in parallel.
👶🏻 Easy & hassle-free configuration The configuration was updated, unused features were removed. Configuration is now easier to understand and more stream lined.
🗻 Supports for large queries & responses IGUANA can handle now queries and responses that are larger than 2GB.
💎 Native executable For Linux, we offer now a native executable (powered by GraalVM) that works without any dependencies. Just download and run it.

As a complete rework, more or less everything changed. In particular:

Comparison with results from previous version is not valid.
Command-line interface changed.
Configuration file layout changed.
RDF Result file format changed.
Most internal classes and APIs changed.
Custom implementations for workers or result processors (we are not aware of any) are not supported anymore.
