An advanced and highly optimized Java library to build frameworks: it's useful for scanning class paths, generating classes at runtime, facilitating the use of reflection, scanning the filesystem, executing stringified source code and much more... (by burningwave)
Project mention: Otter, Fastest Go in-memory cache based on S3-FIFO algorithm | news.ycombinator.com | 2023-12-23/u/someplaceguy,
Those LIRS traces, along with many others, available at this page [1]. I did a cursory review using their traces using Caffeine's and the author's simulators to avoid bias or a mistaken implementation. In their target workloads Caffeine was on par or better [2]. I have not seen anything novel in this or their previous works and find their claims to be easily disproven, so I have not implement this policy in Caffeine simulator yet.

Project mention: Does anyone know any good java implementations for distributed key-value store? | /r/ExperiencedDevs | 2023-06-08You're probably looking for Hazelcast here. Note that it does much more than just a distributed k/v, but it will get you where you need to go.
I decided to start with an overview of what open-source options are currently available. When it comes to the implementation of the on-heap cache mechanism, the options are numerous – there is well known: guava, ehcache, caffeine and many other solutions. However, when I began researching cache mechanisms offering the possibility of storing data outside GC control, I found out that there are very few solutions left. Out of the popular ones, only Terracotta is supported. It seems that this is a very niche solution and we do not have many options to choose from. In terms of less-known projects, I came across Chronicle-Map, MapDB and OHC. I chose the last one because it was created as part of the Cassandra project, which I had some experience with and was curious about how this component worked:
