Introduction

Kiss (keep it simple server), is a simple micro service toolkit, with batteries included to ship it to production with no effort.

Goals

Simple

Simple to understand, and easy to start.
Production ready

Fetch the following csv files and get top 10 rating movies.

It follows the interface (trait) oriented programming style.

Prerequisites

Install graalvm.

sdk install java 22.3.r19-grl

Change current JVM to graalvm.

sdk use java 22.3.r19-grl

Install Graal js following the guide.

Build a persistent, high availability and low latency key-value storage engine for derived data. One of such use cases is feature store. These use cases share some common characteristics, that we could utililze to build a better performing database.

The data is derived, so no need to handle replication or data recovery.
All the writes are through bulk loading, so no concurrency control needed.

In summary, it's like a scalable cache engine.

Features

High throughput bulk load
