 Closely mimicking real-world production environments, we've set up diverse testing scenarios including insertion, searching, and filtered searching. To provide you with credible and reliable data, we've included public datasets from actual production scenarios, such as [SIFT](http://corpus-texmex.irisa.fr/), [GIST](http://corpus-texmex.irisa.fr/), [Cohere](https://huggingface.co/datasets/Cohere/wikipedia-22-12/tree/main/en), and a dataset generated by OpenAI from an opensource [raw dataset](https://huggingface.co/datasets/allenai/c4). It's fascinating to discover how a relatively unknown open-source database might excel in certain circumstances!
