引言:

Linkis 在上层应用和底层引擎之间构建了一层计算中间件,上层应用只需对接 Linkis 提供的 REST/WS/JDBC 等标准接口,就能连接到 MySQL/Spark/Hive/Presto/Flink 等各种底层计算存储引擎,并实现上层应用间的互通。

作为计算中间件,提供强大的连通,复用,扩展和管控能力。并通过解耦应用层和引擎层,简化复杂的网状调用关系,降低整体复杂度和开发、运维成本。

自2019年开源以来,累计试用企业近 700 家,沙箱试用用户 1000+,涉及 互联网、金融、通信等多个行业,被很多企业用作大数据平台底层计算存储引擎组件的统一入口。

没有 Linkis 之前如下:

有了 Linkis 之后如下:

Linkis效果图

基于Linkis计算中间件的架构设计理念,我们在上层构建了很多的应用系统。目前已开源的有:

更多工具准备开源中,敬请期待!


核心特点:

  • 丰富的底层计算存储引擎支持度

    目前支持的计算存储引擎有:Spark、Hive、Python、Presto、ElasticSearch、MLSQL、TiSpark、JDBC和Shell等。

    正在支持中的计算存储引擎有:Flink、Impala和Clickhouse等。

    支持的脚本语言有:SparkSQL、Scala、Pyspark、R、Python、JDBC、HiveQL和Shell等;

  • 强大的计算治理能力。Linkis 1.0 总体分为三大模块:公共增强服务、计算治理服务、微服务治理服务。三大模块简介如下:

    1. 公共增强服务为 Linkis 0.X 已经提供的物料库服务、上下文服务、数据源服务和公共服务等;

    2. 微服务治理服务为 Linkis 0.X 已经提供的Spring Cloud Gateway、Eureka和Open Feign,同时 Linkis1.0 还会提供对 Nacos 的支持;

    3. 计算治理服务是 Linkis 1.0 的核心重点,从 提交 —> 准备 —> 执行三个阶段,来全面升级Linkis 对 用户任务的执行管控能力。

  • 全栈计算存储引擎架构支持。作为计算中间件,将接收、执行和管理针对各种计算存储引擎的任务和请求,包括离线批量任务、交互式查询任务、实时流式任务和存储型任务,并提供强大的复用、预热、限流、切换、全生命周期管理等计算治理能力;

  • 更强大的资源管理能力。 ResourceManager 不仅具备 Linkis0.X 对 Yarn 和 Linkis EngineManager 的资源管理能力,还将提供基于标签的多级资源分配和回收能力,让 ResourceManager 具备跨集群、跨计算资源类型的强大资源管理能力。

  • 全流程标签化。基于多级组合标签,提供跨IDC、跨集群的计算任务路由管控能力,和EngineConnManager, EngineConn 的多租户隔离能力;

  • 统一上下文服务。统一用户和系统资源文件(JAR、ZIP、Properties等),跨用户、系统、计算引擎的参数和变量统一管理,一处设置,处处自动引用;

  • 统一物料。系统和用户级物料管理,可分享和流转,跨用户、系统共享物料,支持全生命周期自动管理;
