Doux is built upon the open-source code of Bourbon. Bourbon is a fine-tuned version of Wisckey using learned indexes. Bourbon's source code is here. Since Bourbon already implements Wisckey, we extend it by integrating our method (Doux) along with other comparable approaches, such as DiffKV.
For detailed instructions on reproducing our experiments, please check out ARTIFACT_README for step-by-step guidance on reimplementation.
