Embedded Event Processing for Java

Embedding Event Processing for Java

Status

Experimental.

Overview

eep.java is a small lightweight subset of Complex Event Processing (CEP) that adds aggregate functions and windowed stream operations to Java. It is a straight forward port of eep.js to Java. To understand the motivation, then, read the introduction to eep.js. If you prefer PHP, then Ian Barber has ported eep.js adding a React PHP edition to the eep.star family. Get Ian's eep.php there.

This version is different. Java generics are supported.

Simple Event Processing

There are a number of excellent projects for monitoring/metrics systems already available in Java, such as yammer, which inspired (my favorite Erlang monitoring package) folsom. There is also Servo by Netflix which has a very easy to use and well designed API. Both do what they say on the tin. If you need a monitoring or metrics system use those.

If you want lower level building blocks, eep.java gives you four different types of windowed event processing with pluggable aggregate functions.
