Crate
CrateDB is a distributed SQL database that makes it simple to store and analyze massive amounts of data in real-time. Built on top of Lucene.
Project mention: Distributed query execution in CrateDB: What you need to know | dev.to | 2022-07-20A logical execution plan does not take into account the information about data distribution. CrateDB is a distributed database and data is sharded: a table can be split into many parts - so-called shards. Shards can be independently replicated and moved from one node to another. The number of shards a table can have is specified at the time the table is created.

elasticsearch-learning-to-rank
Plugin to integrate Learning to Rank (aka machine learning for better relevance) with Elasticsearch
Project mention: New free tool that uses fine-tuned BERT model to surface answers from research papers | reddit.com/r/LanguageTechnology | 2022-10-28I worked on a learning-to-rank problem at a previous job (which unfortunately never got deployed womp, womp). This was early days, so at the time I was looking at using LambdaMART with solr or elasticsearch for reranking with a Bayesian click model to get pseudo-labels for relevance.

Springy-Store-Microservices
Springy Store is a conceptual simple μServices-based project using the latest cutting-edge technologies, to demonstrate how the Store services are created to be a cloud-native and 12-factor app agnostic. Those μServices are developed based on Spring Boot & Cloud framework that implements cloud-native intuitive, design patterns, and best practices.

Project mention: Hot reload SSL configuration for a server and http client | reddit.com/r/scala | 2022-06-12
Hi, I have been working on a small library to make hot reloading of a ssl configuration for a server and http client possible. I was just curious why we needed to restart the server or recreate a http client with new ssl configuration when the keystores needed to be updated. I wanted to learn how the ssl configuration is handled in java and was just curious if I could be able to bypass this limitation and reload the ssl configuration instantly. An alternative would be to use nginx as a proxy with ssl configuration for a server setup, but I was a bit bored and wanted to achieve this just in java. In the above demo I demonstrate a spring boot with embedded jetty server, however similar behaviour is possible with akka or other servers which use SSLContext, SSLSocketFactory, SSLEngine, TrustManager or KeyManager. The server has an initial ssl configuration and it will get updated by an admin application from the terminal through an https request, but it can also use a file listener to update it. If the keystores on the filesystem get replaced or updated it can also pick that up or fetch it from a database based on a trigger or something else. The demo can be found here https://github.com/Hakky54/java-tutorials/tree/main/instant-server-ssl-reloading I use my own library to have this setup working, which is available here: https://github.com/Hakky54/sslcontext-kickstart
