id="end-to-end-exactly-once-applications-with-apache-flink-and-apache-kafka-and-twophasecommitsinkfunction">End-to-end
Exactly Once Applications with Apache Flink and Apache Kafka and
TwoPhaseCommitSinkFunction</h3>
-
-<p>Flink 1.4 includes a first version of an exactly-once producer for
Apache Kafka 0.11. This producer
-enables developers who build Flink applications with Kafka as a data source
and sink to compute
-exactly-once results not just within the Flink program, but truly “end-to-end”
in the application.</p>
-
-<p>The common pattern used for exactly-once applications in Kafka and in
other sinks–the two-phase
-commit algorithm–has been extracted in Flink 1.4.0 into a common class, the
-TwoPhaseCommitSinkFunction (<a
href="https://issues.apache.org/jira/browse/FLINK-7210">FLINK-7210</a>).
This
-will make it easier for users to create their own exactly-once data sinks in
the future.</p>
-
-<h3 id="table-api-and-streaming-sql-enhancements">Table API
and Streaming SQL Enhancements</h3>
-
-<p>Flink SQL now supports windowed joins based on processing time and
event time
-(<a
href="https://issues.apache.org/jira/browse/FLINK-5725">FLINK-5725</a>).
Users will be able to execute a
-join between 2 streaming tables and compute windowed results according to
these 2 different concepts
-of time. The syntax and semantics in Flink are the same as standard SQL with
JOIN and with Flink’s
-streaming SQL more broadly.</p>
-
-<p>Flink SQL also now supports “INSERT INTO SELECT” queries, which makes
it possible to write results
-from SQL directly into a data sink (an external system that receives data from
a Flink application).
-This improves operability and ease-of-use of Flink SQL.</p>
-
-<p>The Table API now supports aggregations on streaming tables;
previously, the only supported
-operations on streaming tables were projection, selection, and union
-(<a
href="https://issues.apache.org/jira/browse/FLINK-4557">FLINK-4557</a>).
This feature was initially discussed in Flink
-Improvement Proposal 11: <a
href="https://cwiki.apache.org/confluence/display/FLINK/FLIP-11%3A+Table+API+Stream+Aggregations">FLIP-11</a>.</p>
-
-<p>The release also adds support for new table API and SQL sources and
sinks, including a Kafka 0.11
-source and JDBC sink.</p>
-
-<p>Lastly, Flink SQL now uses Apache Calcite 1.14, which was just
released in October 2017
-(<a
href="https://issues.apache.org/jira/browse/FLINK-7051">FLINK-7051</a>).</p>
-
-<h3
id="a-significantly-improved-dependency-structure-and-reversed-class-loading">A
Significantly-Improved Dependency Structure and Reversed Class
Loading</h3>
-
-<p>Flink 1.4.0 shades a number of dependences and subtle runtime
conflicts, including:</p>
-
-<ul>
- <li>ASM</li>
- <li>Guava</li>
- <li>Jackson</li>
- <li>Netty</li>
- <li>Apache Zookeeper</li>
-</ul>
-
-<p>These changes improve Flink’s overall stability and removes friction
when embedding Flink or calling
-Flink “library style”.</p>
-
-<p>The release also introduces default reversed (child-first) class
loading for dynamically-loaded user
-code, allowing for different dependencies than those included in the core
framework.</p>
-
-<p>For details on those changes please check out the relevant Jira
issues:</p>
-
-<ul>
- <li><a
href="https://issues.apache.org/jira/browse/FLINK-7442">FLINK-7442</a></li>
- <li><a

-</ul>
-
-<h3 id="hadoop-free-flink">Hadoop-free Flink</h3>
-
-<p>Apache Flink users without any Apache Hadoop dependencies can now run
Flink without Hadoop. Flink
-programs that do not rely on Hadoop components can now be much smaller, a
benefit particularly in a
-container-based setup resulting in less network traffic and better
performance.</p>
-
-<p>This includes the addition of Flink’s own Amazon S3 filesystem
implementations based on Hadoop’s S3a
-and Presto’s S3 file system with properly shaded dependencies (<a
href="https://issues.apache.org/jira/browse/FLINK-5706">FLINK-5706</a>).</p>
-
-<p>The details of these changes regarding Hadoop-free Flink are
available in the Jira issue:
-<a
href="https://issues.apache.org/jira/browse/FLINK-2268">FLINK-2268</a>.</p>
-
-<h3 id="improvements-to-flink-internals">Improvements to Flink
Internals</h3>
-
-<p>Flink 1.4.0 introduces a new blob storage architecture that was first
discussed in
-<a
href="https://cwiki.apache.org/confluence/display/FLINK/FLIP-19%3A+Improved+BLOB+storage+architecture">Flink
Improvement Proposal 19</a> (<a
href="https://issues.apache.org/jira/browse/FLINK-6916">FLINK-6916</a>).</p>
-
-<p>This will enable easier integration with both the work being done in
<a
href="https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=65147077">Flink
Improvement Proposal 6</a> in
-the future and with other improvements in the 1.4.0 release, such as support
for messages larger
-than the maximum Akka Framesize (<a
href="https://issues.apache.org/jira/browse/FLINK-6046">FLINK-6046</a>).</p>
-
-<p>The improvement also enables Flink to leverage distributed file
systems in high availability
-settings for optimized distribution of deployment data to
TaskManagers.</p>
-
-<h3
id="improvements-to-the-queryable-state-client">Improvements to
the Queryable State Client</h3>
-
-<p>Flink’s <a
href="https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/stream/state/queryable_state.html">queryable
state</a> makes it possible for users to access application state
directly in Flink
-before the state has been sent to an external database or key-value
store.</p>
-
-<p>Flink 1.4.0 introduces a range of improvements to the queryable state
client, including a more
-container-friendly architecture, a more user-friendly API that hides
configuration parameters, and
-the groundwork to be able to expose window state (the state of an in-flight
window) in the future.</p>
-
-<p>For details about the changes to queryable state please refer to the
umbrella Jira issue:
-<a
href="https://issues.apache.org/jira/browse/FLINK-5675">FLINK-5675</a>.</p>
-
-<h3 id="metrics-and-monitoring">Metrics and
Monitoring</h3>
-
-<p>Flink’s metrics system now also includes support for Prometheus, an
increasingly-popular metrics and
-reporting system within the Flink community (<a
href="https://issues.apache.org/jira/browse/FLINK-6221">FLINK-6221</a>).</p>
-
-<p>And the Apache Kafka connector in Flink now exposes metrics for
failed and successful offset commits
-in the Kafka consumer callback (<a
href="https://issues.apache.org/jira/browse/FLINK-6998">FLINK-6998</a>).</p>
-
-<h3 id="connector-improvements-and-fixes">Connector
improvements and fixes</h3>
-
-<p>Flink 1.4.0 introduces an Apache Kafka 0.11 connector and, as
described above, support for an
-exactly-once producer for Kafka 0.11 (<a
href="https://issues.apache.org/jira/browse/FLINK-6988">FLINK-6988</a>).</p>
-
-<p>Additionally, the Flink-Kafka consumer now supports dynamic partition
discovery &amp; topic discovery
-based on regex. This means that the Flink-Kafka consumer can pick up new Kafka
partitions without
-needing to restart the job and while maintaining exactly-once guarantees
-(<a
href="https://issues.apache.org/jira/browse/FLINK-4022">FLINK-4022</a>).</p>
-
-<p>Flink’s Apache Kinesis connector now uses an updated version of the
Kinesis Consumer Library and
-Kinesis Consumer Library. This introduces improved retry logic to the
connector and should
-significantly reduce the number of failures caused by Flink writing too
quickly to Kinesis
-(<a
href="https://issues.apache.org/jira/browse/FLINK-7366">FLINK-7366</a>).</p>
-
-<p>Flink’s Apache Cassandra connector now supports Scala
tuples–previously, only streams of Java
-tuples were supported (<a
href="https://issues.apache.org/jira/browse/FLINK-4497">FLINK-4497</a>).
Also, a bug was fixed in
-the Cassandra connector that caused messages to be lost in certain instances
-(<a
href="https://issues.apache.org/jira/browse/FLINK-4500">FLINK-4500</a>).</p>
-
-<h2 id="release-notes---please-read">Release Notes - Please
Read</h2>
-
-<p>Some of these changes will require updating the configuration or
Maven dependencies for existing
-programs. Please read below to see if you might be affected.</p>
-
-<h3 id="changes-to-dynamic-class-loading-of-user-code">Changes
to dynamic class loading of user code</h3>
-
-<p>As mentioned above, we changed the way Flink loads user code from the
previous default of
-<em>parent-first class loading</em> (the default for Java) to
<em>child-first classloading</em>, which is a common
-practice in Java Application Servers, where this is also referred to as
inverted or reversed class
-loading.</p>
-
-<p>This should not affect regular user code but will enable programs to
use a different version of
-dependencies that come with Flink – for example Akka, netty, or Jackson. If
you want to change back
-to the previous default, you can use the configuration setting
<code>classloader.resolve-order: parent-first</code>,
-the new default being <code>child-first</code>.</p>
-
-<h3 id="no-more-avro-dependency-included-by-default">No more
Avro dependency included by default</h3>
-
-<p>Flink previously included Avro by default so user programs could
simply use Avro and not worry about
-adding any dependencies. This behavior was changed in Flink 1.4 because it can
lead to dependency
-clashes.</p>
-
-<p>You now must manually include the Avro dependency
(<code>flink-avro</code>) with your program jar (or add it to
-the Flink lib folder) if you want to use Avro.</p>
-
-<h3 id="hadoop-free-flink-1">Hadoop-free Flink</h3>
-
-<p>Starting with version 1.4, Flink can run without any Hadoop
dependencies present in the Classpath.
-Along with simply running without Hadoop, this enables Flink to dynamically
use whatever Hadoop
-version is available in the classpath.</p>
-
-<p>You could, for example, download the Hadoop-free release of Flink but
use that to run on any
-supported version of YARN, and Flink would dynamically use the Hadoop
dependencies from YARN.</p>
-
-<p>This also means that in cases where you used connectors to HDFS, such
as the <code>BucketingSink</code> or
-<code>RollingSink</code>, you now have to ensure that you either
use a Flink distribution with bundled Hadoop
-dependencies or make sure to include Hadoop dependencies when building a jar
file for your
-application.</p>
-
-<h3 id="bundled-s3-filesystems">Bundled S3
FileSystems</h3>
-
-<p>Flink 1.4 comes bundled with two different S3 FileSystems based on
the Presto S3 FileSystem and
-the Hadoop S3A FileSystem. They don’t have dependencies (because all
dependencies are
-shaded/relocated) and you can use them by dropping the respective file from
the <code>opt</code> directory
-into the <code>lib</code> directory of your Flink installation.
For more information about this, please refer
-to the <a
href="https://ci.apache.org/projects/flink/flink-docs-release-1.4/ops/filesystems.html#built-in-file-systems">documentation</a>.</p>

maintain.</p>
+<p>这是对我们想要维护的代码和质量标准的一种尝试。</p>
-<p>A code contribution (or any piece of code) can be evaluated in various
ways: One set of properties is whether the code is correct and efficient. This
requires solving the <em>logical or algorithmic problem</em> correctly and
well.</p>
+<p>一次代码贡献(或者任何代码片段)可以从很多角度进行评价：一组评判标准是代码是否正确和高效。这需要正确且良好的解决<em>逻辑或算法</em>问题。</p>
-<p>Another set of properties is whether the code follows an intuitive design
and architecture, whether it is well structured with right separation of
concerns, and whether the code is easily understandable and makes its
assumptions explicit. That set of properties requires solving the <em>software
engineering problem</em> well. A good solution implies that the code is easily
testable, maintainable also by other people than the original authors (because
it is harder to accidentally break) [...]
+<p>另一组评判标准是代码是否使用了简洁的设计和架构，是否通过概念分离实现了良好的架构，是否足够简单易懂并且明确假设。该评判标准需要良好的解决软件工程问题。一个好的解决方案需要代码是容易被测试的，可以被除了原作者之外的其他人维护的（因为打破之后再维护是非常困难的），同时还需要能够高效的迭代演进的。</p>
-<p>While the first set of properties has rather objective approval criteria,
the second set of properties is much harder to assess, but is of high
importance for an open source project like Apache Flink. To make the code base
inviting to many contributors, to make contributions easy to understand for
developers that did not write the original code, and to make the code robust in
the face of many contributions, well engineered code is crucial.<sup

+<p>不过第一组标准有相当客观的达成条件，相比之下要达到第二组评判标准更加困难，但是对于 Apache Flink
这样的开源项目来说却非常重要。为了能够吸引更多贡献者，为了的开源贡献能够更容易被开发者理解，同时也为了众多开发者同时开发时代码的健壮性，良好工程化的代码是至关重要的。对于良好的工程代码来说，更加容易保证代码的正确性和高效不会随着时间的推移受到影响</p>
-<p>This is of course not a full guide on how to write well engineered code.
There is a world of big books that try to capture that. This guide is meant as
a checklist of best practices, patterns, anti-patterns, and common mistakes
that we observed in the context of developing Flink.</p>
+<p>当然，本指南并不是一份如何写出良好的工程代码的全方位指导。有相当多的书籍尝试说明如何实现良好的代码。本指南只是作为最佳实践的检查清单，包括我们在开发
Flink 过程中遇到的模式，反模式和常见错误。</p>
-<p>A big part of high-quality open source contributions is about helping the
reviewer to understand the contribution and double-check the implications, so
an important part of this guide is about how to structure a pull request for
review.</p>
