Apache Kafka is a distributed event store and stream-processing platform. It is an open-source system developed by the Apache Software Foundation written in Java and Scala.The project aims to provide a unified, high-throughput, low-latency platform for handling real-time data feeds.
The message queue paradigm is a sibling of the publisher/subscriber pattern, and is typically one part of a larger message-oriented middleware system. Most messaging systems support both the publisher/subscriber and message queue models in their API, e.g. Java Message Service (JMS).
A message broker is an architectural pattern for message validation, transformation, and routing. It mediates communication among applications [ vague ] , minimizing the mutual awareness that applications should have of each other in order to be able to exchange messages, effectively implementing decoupling .
BeepBeep, a simple and lightweight Java-based event stream processing library from the Formal Computer Science Lab at Université du Québec à Chicoutimi Brook language from Stanford CAL Actor Language : a high-level programming language for writing (dataflow) actors, which are stateful operators that transform input streams of data objects ...
MapReduce is a programming model and an associated implementation for processing and generating big data sets with a parallel and distributed algorithm on a cluster. [1] [2] [3]A MapReduce program is composed of a map procedure, which performs filtering and sorting (such as sorting students by first name into queues, one queue for each name), and a reduce method, which performs a summary ...
Batik: pure Java library for SVG content manipulation; FOP: Java print formatter driven by XSL formatting objects (XSL-FO); supported output formats include PDF, PS, PCL, AFP, XML (area tree representation), Print, AWT and PNG, and to a lesser extent, RTF and TXT; XML Graphics Commons: common components for Apache Batik and Apache FOP
The Jakarta Messaging API (formerly Java Message Service or JMS API) is a Java application programming interface (API) for message-oriented middleware. It provides generic messaging models, able to handle the producer–consumer problem , that can be used to facilitate the sending and receiving of messages between software systems . [ 1 ]
In the publish–subscribe model, subscribers typically receive only a subset of the total messages published. The process of selecting messages for reception and processing is called filtering. There are two common forms of filtering: topic-based and content-based. In a topic-based system, messages are published to "topics" or named logical ...
