-<title>The State Processor API: How to Read, write and modify the state of Flink applications</title>
-<description><p>Whether you are running Apache Flink<sup>Ⓡ</sup> in production or evaluated Flink as a computation framework in the past, you’ve probably found yourself asking the question: How can I access, write or update state in a Flink savepoint? Ask no more! <a href="https://flink.apache.org/news/2019/08/22/release-1.9.0.html">Apache Flink 1.9.0</a> introduces the <a href="https://nightlies.apache.org/flink/flink-docs-release-1.9/dev/ [...]
-
-<p>In this post, we explain why this feature is a big step for Flink, what you can use it for, and how to use it. Finally, we will discuss the future of the State Processor API and how it aligns with our plans to evolve Flink into a system for <a href="https://flink.apache.org/news/2019/02/13/unified-batch-streaming-blink.html">unified batch and stream processing</a>.</p>
-
-<h2 id="stateful-stream-processing-with-apache-flink-until-flink-19">Stateful Stream Processing with Apache Flink until Flink 1.9</h2>
-
-<p>All non-trivial stream processing applications are stateful and most of them are designed to run for months or years. Over time, many of them accumulate a lot of valuable state that can be very expensive or even impossible to rebuild if it gets lost due to a failure. In order to guarantee the consistency and durability of application state, Flink featured a sophisticated checkpointing and recovery mechanism from very early on. With every release, the Flink community has added mo [...]
-
-<p>However, a feature that was commonly requested by Flink users was the ability to access the state of an application “from the outside”. This request was motivated by the need to validate or debug the state of an application, to migrate the state of an application to another application, to evolve an application from the Heap State Backend to the RocksDB State Backend, or to import the initial state of an application from an external system like a relational database.</p>
-
-<p>Despite all those convincing reasons to expose application state externally, your access options have been fairly limited until now. Flink’s Queryable State feature only supports key-lookups (point queries) and does not guarantee the consistency of returned values (the value of a key might be different before and after an application recovered from a failure). Moreover, queryable state cannot be used to add or modify the state of an application. Also, savepoints, which are consi [...]

-<h2 id="reading-and-writing-application-state-with-the-state-processor-api">Reading and Writing Application State with the State Processor API</h2>
-
-<p>The State Processor API that comes with Flink 1.9 is a true game-changer in how you can work with application state! In a nutshell, it extends the DataSet API with Input and OutputFormats to read and write savepoint or checkpoint data. Due to the <a href="https://nightlies.apache.org/flink/flink-docs-master/dev/table/common.html#integration-with-datastream-and-dataset-api">interoperability of DataSet and Table API</a>, you can even use relational Table API [...]
-
-<p>For example, you can take a savepoint of a running stream processing application and analyze it with a DataSet batch program to verify that the application behaves correctly. Or you can read a batch of data from any store, preprocess it, and write the result to a savepoint that you use to bootstrap the state of a streaming application. It’s also possible to fix inconsistent state entries now. Finally, the State Processor API opens up many ways to evolve a stateful application th [...]
-
-<h2 id="mapping-application-state-to-datasets">Mapping Application State to DataSets</h2>
-
-<p>The State Processor API maps the state of a streaming application to one or more data sets that can be separately processed. In order to be able to use the API, you need to understand how this mapping works.</p>
-
-<p>But let’s first have a look at what a stateful Flink job looks like. A Flink job is composed of operators, typically one or more source operators, a few operators for the actual processing, and one or more sink operators. Each operator runs in parallel in one or more tasks and can work with different types of state. An operator can have zero, one, or more <em>“operator states”</em> which are organized as lists that are scoped to the operator’s tasks. If the operator [...]
-
-<p>The following figure shows the application “MyApp” which consists of three operators called “Src”, “Proc”, and “Snk”. Src has one operator state (os1), Proc has one operator state (os2) and two keyed states (ks1, ks2) and Snk is stateless.</p>

- <img src="/img/blog/2019-09-13-state-processor-api-blog/application-my-app-state-processor-api.png" width="600px" alt="Application: My App" />
-</p>
-
-<p>A savepoint or checkpoint of MyApp consists of the data of all states, organized in a way that the states of each task can be restored. When processing the data of a savepoint (or checkpoint) with a batch job, we need a mental model that maps the data of the individual tasks’ states into data sets or tables. In fact, we can think of a savepoint as a database. Every operator (identified by its UID) represents a namespace. Each operator state of an operator is mapped to a dedicate [...]

- <img src="/img/blog/2019-09-13-state-processor-api-blog/database-my-app-state-processor-api.png" width="600px" alt="Database: My App" />
-</p>
-
-<p>The figure shows how the values of Src’s operator state are mapped to a table with one column and five rows, one row for all list entries across all parallel tasks of Src. Operator state os2 of the operator “Proc” is similarly mapped to an individual table. The keyed states ks1 and ks2 are combined to a single table with three columns, one for the key, one for ks1 and one for ks2. The keyed table holds one row for each distinct key of both keyed states. Since the operator “Snk” [...]
-
-<p>The State Processor API now offers methods to create, load, and write a savepoint. You can read a DataSet from a loaded savepoint or convert a DataSet into a state and add it to a savepoint. DataSets can be processed with the full feature set of the DataSet API. With these building blocks, all of the before-mentioned use cases (and more) can be addressed. Please have a look at the <a href="https://nightlies.apache.org/flink/flink-docs-release-1.9/dev/libs/state_processor [...]

-<h2 id="why-dataset-api">Why DataSet API?</h2>
-
-<p>In case you are familiar with <a href="https://flink.apache.org/roadmap.html">Flink’s roadmap</a>, you might be surprised that the State Processor API is based on the DataSet API. The Flink community plans to extend the DataStream API with the concept of <em>BoundedStreams</em> and deprecate the DataSet API. When designing this feature, we also evaluated the DataStream API or Table API but neither could provide the right feature set yet. Since w [...]

-<h2 id="summary">Summary</h2>
-
-<p>Flink users have requested a feature to access and modify the state of streaming applications from the outside for a long time. With the State Processor API, Flink 1.9.0 finally exposes application state as a data format that can be manipulated. This feature opens up many new possibilities for how users can maintain and manage Flink streaming applications, including arbitrary evolution of stream applications and exporting and bootstrapping of application state. To put it concise [...]

- <p><strong>Avoid gender- and culture-specific language.</strong> There is no need to identify

-Also, jargon and conventions that you take for granted in your own language

- <h3>Best Practice</h3>

-<p>This style guide has the overarching goal of setting the foundation for
-documentation that is <strong>Accessible</strong>, <strong>Consistent</strong>, <strong>Objective</strong>,
-<strong>Logical</strong> and <strong>Inclusive</strong>.</p>
+<p>本风格指南的首要目标是为写出<strong>易读</strong>、<strong>一致</strong>、<strong>客观</strong>、<strong>合乎逻辑</strong>以及<strong>全面</strong>的文档奠定基础。</p>
-<h4 id="accessible">Accessible</h4>
+<h4 id="section-16">易读的</h4>
-<p>The Flink community is diverse and international, so you need to think wide and
-globally when writing documentation. Not everyone speaks English at a native
-level and the level of experience with Flink (and stream processing in general)
-ranges from absolute beginners to experienced advanced users. Ensure technical
-accuracy and linguistic clarity in the content you produce so that it can be
-understood by all users.</p>
+<p>Flink 社区是多元化和国际化的，所以在编写文档时需要放眼全球。不是每个人的母语都是英语，而且使用 Flink （以及一般的流处理）的经验也是从初学者到资深不等。因此要确保内容的技术准确性以及语言清晰度，以便所有的用户都能理解。</p>
-<h4 id="consistent">Consistent</h4>
+<h4 id="section-17">一致的</h4>
-<p>Stick to the basic guidelines detailed in this style guide and use your own
-best judgment to uniformly spell, capitalize, hyphenate, bold and italicize
-text. Correct grammar, punctuation and spelling are desirable, but not a hard
-requirement — documentation contributions are open to any level of language
-proficiency.</p>
+<p>坚持本样式指南中详细的基本准则，并用自己的最佳判断来统一拼写、大小写、连字符、粗体和斜体。正确的语法、标点符号和拼写是值得做的，但并不是必须的–贡献文档对任何语言熟练度都是开放的。</p>
-<h4 id="objective">Objective</h4>
+<h4 id="section-18">客观的</h4>
-<p>Keep your sentences short and to the point. As a rule of thumb, if a sentence
-is shorter than 14 words, readers will likely understand 90 percent of its
-content. Sentences with more than 25 words are usually harder to understand and
-should be revised and split, when possible. Being concise and using well-known
-keywords also allows users to navigate to relevant documentation with little
-effort.</p>
+<p>句子应该简洁和提纲挈领。根据经验，如果一个句子少于 14 个单词，读者就会很容易理解 90% 的内容。但如果大于 25 个单词通常就会很难理解了，应尽可能修改和拆分。简明和众所周知的关键词能让用户轻松的定位到相关的文档。</p>
-<h4 id="logical">Logical</h4>
+<h4 id="section-19">合乎逻辑的</h4>
-<p>Be mindful that most users will scan through online content and only read
-around <a href="https://www.nngroup.com/articles/website-reading/">28 percent of it</a>.
-This underscores the importance of grouping related ideas together into a clear
-hierarchy of information and using focused, descriptive headings. Placing the
-most relevant information in the first two paragraphs of each section is a good
-practice that increases the “return of time invested” for the user.</p>
+<p>请注意，大部分用户只会浏览大约 <a href="https://www.nngroup.com/articles/website-reading/">28% 的在线内容</a> 。这突出表明了将相关的概念按照清晰的信息结构分组、内容聚焦以及使用描述性标题的重要性。将最相关的内容放在每个章节的头两个段落是很好的实践，这样能增加用户的“时间投入回报”。</p>
-<h4 id="inclusive">Inclusive</h4>
+<h4 id="section-20">全面的</h4>
-<p>Use positive language and concrete, relatable examples to ensure the content is
-findable and welcoming to all users. The documentation is translated to other
-languages, so using simple language and familiar words also helps reduce the
-translation effort.</p>
+<p>使用积极主动的语法以及准确、有关联性的样例，以确保内容可被检索到并且对所有用户都是友好可读的。文档也会被翻译成其他语言，所以使用简单的语法和熟悉的单词有助于减少翻译的工作量。</p>
