Linkis EngineConn简介<a class="hash-link" href="#6-linkis-engineconn简介" title="Direct link to heading">#</a></h2><p> <!-- --> <!-- --> <!-- --> <!-- --> EngineConn，即原 Engine 模块，作为 Linkis 与底层计算存储引擎进行连接和交互的实际单元，是 Linkis 提供计算存储能力的基础。</p><p> <!-- --> <!-- --> <!-- --> <!-- --> Linkis1.0 的 EngineConn 主要由 EngineConn 和 Executor构成。其中：</p><p>a) EngineConn 为连接器，包含引擎与具体集群的会话信息。它只是起到一个连接，一个客户端的作用，并不真正的去执行计算。</p><p>b) Executor 为执行器，作为真正的计算场景执行器，是实际的计算逻辑执行单元，也对引擎各种具体能力的抽象，例如提供加锁、访问状态、获取日志等多种不同的服务。</p><p>c) Executor 通过 EngineConn 中的会话信息进行创建，一个引擎类型可以支持多种不同种类的计算任务，每种对应一个 Executor 的实现，计算任务将被提交到对应的 Executor 进行执行。 |
| 这样，同一个引擎能够根据不同的计算场景提供不同的服务。比如常驻式引擎启动后不需要加锁，一次性引擎启动后不需要支持 Receiver 和访问状态等。</p><p>d) 采用 Executor 和 EngineConn 分离的方式的好处是，可以避免 Receiver 耦合业务逻辑，本身只保留 RPC 通信功能。将服务分散在多个 Executor 模块中，并且抽象成几大类引擎：交互式计算引擎、流式引擎、一次性引擎等等可能用到的，构建成统一的引擎框架，便于后期的扩充。 |
| 这样不同类型引擎可以根据需要分别加载其中需要的能力，大大减少引擎实现的冗余。</p><p> <!-- --> <!-- --> <!-- --> <!-- --> 如下图所示：</p><p><img alt="Linkis EngineConn架构图" src="/zh-CN/assets/images/Linkis1.0-EngineConn-architecture-367e10108a33edc9c0babcc82a11fe7b.png"></p></div><footer class="theme-doc-footer docusaurus-mt-lg"><div class="theme-doc-footer-edit-meta-row row"><div class="col"><a href="https://github.com/apache/incubator-linkis-website/edit/dev/i18n/zh-CN/docusaurus-plugin-content-docs/version-1.1.0/architecture/difference_between_1.0_and_0.x.md" target="_blank" rel="noreferrer noopener" class="theme-edit-this-page"><svg fill="currentColor" height="20" width="20" viewBox="0 0 40 40" class="iconEdit_mS5F" aria-hidden="true"><g><path d="m34.5 11.7l-3 3.1-6.3-6.3 3.1-3q0.5-0.5 1.2-0.5t1.1 0.5l3.9 3.9q0.5 0.4 0.5 1.1t-0.5 1.2z m-29.5 17.1l18.4-18.5 6.3 6.3-18.4 18.4h-6.3v-6.2z"></path></g></svg>编辑</a></div><div class="col lastUpdated_mt2f"></div></div></footer></article><nav class="pagination-nav docusaurus-mt-lg" aria-label="Docs pages navigation"><div class="pagination-nav__item"><a class="pagination-nav__link" href="/zh-CN/docs/1.1.0/architecture/overview"><div class="pagination-nav__sublabel">上一篇</div><div class="pagination-nav__label">« <!-- -->总览</div></a></div><div class="pagination-nav__item pagination-nav__item--next"><a class="pagination-nav__link" href="/zh-CN/docs/1.1.0/architecture/job_submission_preparation_and_execution_process"><div class="pagination-nav__sublabel">下一篇</div><div class="pagination-nav__label">Job 提交准备执行流程<!-- --> »</div></a></div></nav></div></div><div class="col col--3"><div class="tableOfContents_vrFS thin-scrollbar"><ul class="table-of-contents table-of-contents__left-border"><li><a href="#1-简述" class="table-of-contents__link">1. 简述</a></li><li><a href="#2-主要特点" class="table-of-contents__link">2. 主要特点</a></li><li><a href="#3-服务对比" class="table-of-contents__link">3. 服务对比</a></li><li><a href="#4-linkis-manager简介" class="table-of-contents__link">4.

Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.</p> |
