Lucene是一种高性能、可伸缩的信息搜索 (IR)库,在2000年开源,最初由鼎鼎大名的Doug Cutting开发。是基于Java实现的高性能的开源项目
Lucene采用了基于倒排表的设计原理,可以非常高效地实现文本查找,在底层采用了分段的存储模式,使它在读写时几乎完全避免了锁的出现,大大提升了读写性能
Elasticsearch是一个基于Lucene的搜索服务器,它提供了一个分布式多用户能力的全文搜索引擎,基于RESTful WEB接口
Elasticsearch是用Java语言开发的,并作为Apache许可条款下的开放源码发布,是一种流行的企业级搜索引擎
Elasticsearch用于云计算中,能够达到实时搜索,稳定,可靠快速
企业搜索:提升任何用例的搜索和发现体验
日志监测:快照且可扩展的日志管理
基础架构监测:对系统质保进行监测和可视化
Maps:实时探索位置数据
SIEM:交互式调查和自动威胁检测
APM:深入洞察应用程序的性能
合成监测:监测可用性问题并进行应对
终端安全:预防、检测、捕获并应对威胁
Elasticsearch是流行的企业搜索引擎之一
Elasticsearch是在Java上开发的,这使得它在几乎所有平台上都兼容
Elasticsearch是实时的,添加的文档秒级就可以在这个引擎中搜索了
Elasticsearch最多可扩展至PB级的结构化和非结构化数据
Elasticsearch可以代替MongoDB等文档存储,是面向文档的数据库
Elasticsearch使用非规范化来提高搜索性能
Elasticsearch是分布式的可以轻松地在任何大型组织中进行扩展和集成
Elasticsearch源代码开放,可在Apache许可版本2.0下使用

消息
消息指的是两个应用之间传递的数据
数据的形式有很多,可能是文本字符串,也可能是嵌入对象
队列
队列是一个数据结构,具有先进先出的特点
是存储消息的介质
消息队列: MQ(Message Queue)
是指利用高效可靠的消息传递机制进行与平台无关的数据交流
基于数据通信来进行分布式系统的集成,是在消息的传输过程中保存消息的容器
消息队列本质上是一个队列,而队列中存放的是一个个消息
AMQP:Advanced Message Queuing Protoco
JMS:Java Message Service应用程序接口
优点:异步处理、应用解耦、流量削峰
缺点:系统可用性降低、系统复杂度提高、一致性问题
ActiveMQ:是Apache旗下一个子项目,基于JMS
Kafka:分布式消息发布订阅系统,专为大数据而生
RocketMQ:基于JMS,阿里系旗下开源的一款分布式消息队列中间件
RabbitMQ:基于AMQP协议,使用Erlang开发的开源消息队列中间件
是一款基于AMQP协议使用Erlang开发的开源消息队列中间件
一种通用的面向并发编程的解释型语言1987年问世,1998年发布第一个开源版本。目标为实现应对大并发活动的编程语言和运行环境
支持多种语言客户端:RabbitMQ几乎支持所有常用编程语言,包括 Java、Python、Ruby 等等
可视化管理界面:RabbitMQ提供一个易用的用户界面,使得用户可以监控和管理消息
插件机制:RabbitMQ提供了许多插件(可以自行开发)灵活的分发消息策略:简单模式、工作队列模式、广播模式、路由模式、通配符模式
支持集群:多台RabbitMQ服务器可以组成一个集群,形成一个逻辑Broker可靠性:支持持久化,传输确认,发布消费确认等保证了MQ的可靠性
