+<title>Apache Flink Kubernetes Operator 1.2.0 Release Announcement</title>
+<description><p>We are proud to announce the latest stable release of
the operator. The 1.2.0 release adds support for the Standalone Kubernetes
deployment mode and includes several improvements to the core logic.</p>
+
+<h2 id="release-highlights">Release Highlights</h2>
+
+<ul>
+ <li>Standalone deployment mode support</li>
+ <li>Improved upgrade flow</li>
+ <li>Readiness and liveness probes</li>
+ <li>Flexible job jar handling</li>
+</ul>
+
+<h2 id="standalone-deployment-mode-support">Standalone
deployment mode support</h2>
+
+<p>Until now the operator relied exclusively on Flink’s built-in Native
Kubernetes integration to deploy and manage Flink clusters. When using the
Native deployment mode the Flink cluster communicates directly with Kubernetes
to allocate/deallocate TaskManager resources on the fly. While this leads to a
very simple deployment model, in some environments it also means higher
security exposure as the user code running on the Flink cluster may gain the
same Kubernetes access privilege [...]
+
+<p>Flink Kubernetes Operator 1.2.0 brings Standalone mode support for
FlinkDeployment resources.</p>
+
+<p>When using the standalone mode, the operator itself sets up the Job
and TaskManager resources for the Flink cluster. Flink processes then run
without any need for Kubernetes access. In fact in this mode the Flink cluster
itself is unaware that it is running in a Kubernetes environment. If unknown or
external code is being executed on the Flink cluster then Standalone mode adds
another layer of security.</p>
+
+<p><strong>The default deployment mode is Native. Native
deployment mode remains the recommended mode for standard operator use and when
running your own Flink jobs.</strong></p>
+
+<p>The deployment mode can be set using the
<code>mode</code> field in the deployment spec.</p>
+

class="p-Indicator">:</span> <span
class="l-Scalar-Plain">native/standalone</span></code></pre></div>
+
+<h2 id="improved-upgrade-flow">Improved upgrade flow</h2>
+<p>There have been a number of important changes that improve the job
submission and upgrade flow. The operator now distinguishes configuration
&amp; spec changes that do not require the redeployment of the Flink
cluster resources (such as setting a new periodic savepoint interval). These
improvements now avoid unnecessary job downtime in many cases.</p>
+
+<p>Leveraging the standalone deployment mode the operator now also
supports rescaling jobs directly using Flink’s reactive scheduler. When
changing the parallelism of an application FlinkDeployment with
<code>mode: standalone</code> set and <code>scheduler-mode:
reactive</code> in the <code>flinkConfiguration</code> the
operator will simply increase the number of TaskManagers to match the new
parallelism and let Flink do the scaling automaticall [...]
+
+<p>There are also some important fixes to problems that might occur when
switching between Flink versions or using the stateless upgrade mode.</p>
+
+<h2 id="readiness-and-liveness-probes">Readiness and Liveness
probes</h2>
+
+<p>From an operational perspective it is very important to be able to
determine the health of the Kubernetes Operator process. The operator now
exposes a health endpoint by default together with a liveness and readiness
probe.</p>
+
+<h2 id="flexible-job-jar-handling">Flexible job jar
handling</h2>
+
+<p>The 1.2.0 release now makes the jobSpec.jarURI parameter optional to
allow users to run jobs using dependencies that are already bundled in the
Flink classpath.</p>
+
+<p>This can be especially valuable in session deployments when multiple
jobs, reusing the same artifacts, are deployed with different
configurations.</p>
+
+<h2 id="release-resources">Release Resources</h2>
+
+<p>The source artifacts and helm chart are now available on the updated
Downloads page of the Flink website.</p>

-<title>No Java Required: Configuring Sources and Sinks in SQL</title>
-<description><h1 id="introduction">Introduction</h1>
-
-<p>The recent <a
href="https://flink.apache.org/news/2020/02/11/release-1.10.0.html">Apache
Flink 1.10 release</a> includes many exciting features.
-In particular, it marks the end of the community’s year-long effort to merge
in the <a
href="https://flink.apache.org/news/2019/02/13/unified-batch-streaming-blink.html">Blink
SQL contribution</a> from Alibaba.
-The reason the community chose to spend so much time on the contribution is
that SQL works.
-It allows Flink to offer a truly unified interface over batch and streaming
and makes stream processing accessible to a broad audience of developers and
analysts.
-Best of all, Flink SQL is ANSI-SQL compliant, which means if you’ve ever used
a database in the past, you already know it<sup
id="fnref:1"><a href="#fn:1"
class="footnote">1</a></sup>!</p>
-
-<p>A lot of work focused on improving runtime performance and
progressively extending its coverage of the SQL standard.
-Flink now supports the full TPC-DS query set for batch queries, reflecting the
readiness of its SQL engine to address the needs of modern data warehouse-like
workloads.
-Its streaming SQL supports an almost equal set of features - those that are
well defined on a streaming runtime - including <a
href="https://nightlies.apache.org/flink/flink-docs-release-1.10/dev/table/streaming/joins.html">complex
joins</a> and <a
href="https://nightlies.apache.org/flink/flink-docs-stable/dev/table/streaming/match_recognize.html">MATCH_RECOGNIZE</a>.</p>
-
-<p>As important as this work is, the community also strives to make
these features generally accessible to the broadest audience possible.
-That is why the Flink community is excited in 1.10 to offer production-ready
DDL syntax (e.g., <code>CREATE TABLE</code>, <code>DROP
TABLE</code>) and a refactored catalog interface.</p>
-
-<h1 id="accessing-your-data-where-it-lives">Accessing Your
Data Where It Lives</h1>
-
-<p>Flink does not store data at rest; it is a compute engine and
requires other systems to consume input from and write its output.
-Those that have used Flink’s <code>DataStream</code> API in the
past will be familiar with connectors that allow for interacting with external
systems.
-Flink has a vast connector ecosystem that includes all major message queues,
filesystems, and databases.</p>
-
-<div class="alert alert-info">
-If your favorite system does not have a connector maintained in the central
Apache Flink repository, check out the <a
href="https://flink-packages.org">flink packages
website</a>, which has a growing number of community-maintained
components.
-</div>
-
-<p>While these connectors are battle-tested and production-ready, they
are written in Java and configured in code, which means they are not amenable
to pure SQL or Table applications.
-For a holistic SQL experience, not only queries need to be written in SQL, but
also table definitions.</p>
-
-<h1 id="create-table-statements">CREATE TABLE
Statements</h1>
-
-<p>While Flink SQL has long provided table abstractions atop some of
Flink’s most popular connectors, configurations were not always so
straightforward.
-Beginning in 1.10, Flink supports defining tables through <code>CREATE
TABLE</code> statements.
-With this feature, users can now create logical tables, backed by various
external systems, in pure SQL.</p>
-
-<p>By defining tables in SQL, developers can write queries against
logical schemas that are abstracted away from the underlying physical data
store. Coupled with Flink SQL’s unified approach to batch and stream
processing, Flink provides a straight line from discovery to
production.</p>
-
-<p>Users can define tables over static data sets, anything from a local
CSV file to a full-fledged data lake or even Hive.
-Leveraging Flink’s efficient batch processing capabilities, they can perform
ad-hoc queries searching for exciting insights.
-Once something interesting is identified, businesses can gain real-time and
continuous insights by merely altering the table so that it is powered by a
message queue such as Kafka.
-Because Flink guarantees SQL queries have unified semantics over batch and
streaming, users can be confident that redeploying this query as a continuous
streaming application over a message queue will output identical
results.</p>

-<h1 id="catalogs">Catalogs</h1>
-
-<p>While being able to create tables is important, it often isn’t enough.
-A business analyst, for example, shouldn’t have to know what properties to set
for Kafka, or even have to know what the underlying data source is, to be able
to write a query.</p>
-
-<p>To solve this problem, Flink 1.10 also ships with a revamped catalog
system for managing metadata about tables and user definined functions.
-With catalogs, users can create tables once and reuse them across Jobs and
Sessions.
-Now, the team managing a data set can create a table and immediately make it
accessible to other groups within their organization.</p>
-
-<p>The most notable catalog that Flink integrates with today is Hive
Metastore.
-The Hive catalog allows Flink to fully interoperate with Hive and serve as a
more efficient query engine.
-Flink supports reading and writing Hive tables, using Hive UDFs, and even
leveraging Hive’s metastore catalog to persist Flink specific
metadata.</p>
-
-<h1 id="looking-ahead">Looking Ahead</h1>
-
-<p>Flink SQL has made enormous strides to democratize stream processing,
and 1.10 marks a significant milestone in that development.
-However, we are not ones to rest on our laurels and, the community is
committed to raising the bar on standards while lowering the barriers to entry.
-The community is looking to add more catalogs, such as JDBC and Apache Pulsar.
-We encourage you to sign up for the <a
href="https://flink.apache.org/community.html">mailing
list</a> and stay on top of the announcements and new features in
upcoming releases.</p>

again to Google Season of Docs (GSoD) this year! If you’re unfamiliar with the
program, GSoD is a great initiative organized by Google Open Source to pair
technical writers with mentors to work on documentation for open source
projects. Does working shoulder to shoulder with the Flink community on
documentation sound exciting? We’d love to hear from you!</p>

+<p>Until now the operator relied exclusively on Flink’s built-in Native
Kubernetes integration to deploy and manage Flink clusters. When using the
Native deployment mode the Flink cluster communicates directly with Kubernetes
to allocate/deallocate TaskManager resources on the fly. While this leads to a
very simple deployment model, in some environments it also means higher
security exposure as the user code running on the Flink cluster may gain the
same Kubernetes access privileges.</p>

FlinkDeployment resources.</p>
-<div class="col-sm-12">
- <hr />
-</div>
+<p>When using the standalone mode, the operator itself sets up the Job and
TaskManager resources for the Flink cluster. Flink processes then run without
any need for Kubernetes access. In fact in this mode the Flink cluster itself
is unaware that it is running in a Kubernetes environment. If unknown or
external code is being executed on the Flink cluster then Standalone mode adds
another layer of security.</p>

remains the recommended mode for standard operator use and when running your

+<h2 id="improved-upgrade-flow">Improved upgrade flow</h2>
+<p>There have been a number of important changes that improve the job
submission and upgrade flow. The operator now distinguishes configuration &
spec changes that do not require the redeployment of the Flink cluster
resources (such as setting a new periodic savepoint interval). These
improvements now avoid unnecessary job downtime in many cases.</p>
-<!-- Updates section -->
+<p>Leveraging the standalone deployment mode the operator now also supports
rescaling jobs directly using Flink’s reactive scheduler. When changing the
parallelism of an application FlinkDeployment with <code>mode:
standalone</code> set and <code>scheduler-mode: reactive</code> in the
<code>flinkConfiguration</code> the operator will simply increase the number of
TaskManagers to match the new parallelism and let Flink do the scaling
automatically (reactively). Same as with the reactive [...]

+<p>There are also some important fixes to problems that might occur when
switching between Flink versions or using the stateless upgrade mode.</p>

+<h2 id="readiness-and-liveness-probes">Readiness and Liveness probes</h2>
-<div class="col-sm-3">
+<p>From an operational perspective it is very important to be able to
determine the health of the Kubernetes Operator process. The operator now
exposes a health endpoint by default together with a liveness and readiness
probe.</p>

+<h2 id="flexible-job-jar-handling">Flexible job jar handling</h2>
-</div>
+<p>The 1.2.0 release now makes the jobSpec.jarURI parameter optional to allow
users to run jobs using dependencies that are already bundled in the Flink
classpath.</p>
-<div class="col-sm-9">

reusing the same artifacts, are deployed with different configurations.</p>
