Adding new Data Sources to Beam SQL CLI
Pablo Estrada
A new, exciting feature that came to Apache Beam is the ability to use SQL in your pipelines. This is done using Beam’s SqlTransform in Java pipelines.
Beam also has a fancy new SQL command line that you can use to query your data interactively, be it Batch or Streaming. If you haven’t tried it, check out https://bit.ly/ExploreBeamSQL.
A nice feature of the SQL CLI is that you can use CREATE EXTERNAL TABLE commands to add data sources to be accessed in the CLI. Currently, the CLI supports creating tables from BigQuery, PubSub, Kafka, and text files. In this post, we explore how to add new data sources, so that you will be able to consume data from other Beam sources.

Beam community update!
Matthias Baetens
The Apache Beam community in 2019 2019 has already been a busy time for the Apache Beam community. The ASF blog featured our way of community building and we’ve had more Beam meetups around the world. Apache Beam also received the Technology of the Year Award from InfoWorld.
As these events happened, we were building up to the 20th anniversary of the Apache Software Foundation. The contributions of the Beam community were a part of Maximilian Michels blog post on the success of the ASF’s open source development model:

— Apache - The ASF (@TheASF) 26 maart 2019 In that spirit, let’s have an overview of the things that have happened, what the next few months look like, and how we can foster even more community growth.
Meetups We’ve had a flurry of activity, with several meetups in the planning process and more popping up globally over time. As diversity of contributors is a core ASF value, this geographic spread is exciting for the community. Here’s a picture from the latest Apache Beam meetup organized at Lyft in San Francisco:
We have more Bay Area meetups coming soon, and the community is looking into kicking off a meetup in Toronto!
London had its first meetup of 2019 at the start of April:
and Stockholm had its second meetup at the start of May:

🎫 If you want to secure your ticket to attend the Beam Summit Europe 2019, check our event page.
💸 If you want to make the Summit even more awesome, check out our sponsor booklet!
We also launched the CfP for our Beam Summit in North America, which will be held in collaboration with ApacheCon.
🎤 If you want to give a talk, take a look at our CfP.
Stay tuned for more information on the summit in North America and Asia.
Why community engagement matters Why we need a strong Apache Beam community:
We’re receiving lots of code contributions and need committers to review those and help onboard new contributors to the project. We want people to feel a sense of ownership to the project. By fostering this level of engagement, the work becomes even more exciting. A healthy community has a further reach and leads to more growth. More hours can be contributed to the project as we can spread the work and ownership. Why are we organizing these summits:
We’d like to give folks a place to meet, congregate, and share ideas. We know that offline interactions often changes the nature of the online ones in a positive manner. Building an active and diverse community is part of the Apache Way. These summits provide an opportunity for us to engage people from different locations, companies, and backgrounds.

Apache Beam: A Look Back at 2017
Anand Iyer &
Jean-Baptiste Onofré
On January 10, 2017, Apache Beam got promoted as a Top-Level Apache Software Foundation project. It was an important milestone that validated the value of the project, legitimacy of its community, and heralded its growing adoption. In the past year, Apache Beam has been on a phenomenal growth trajectory, with significant growth in its community and feature set. Let us walk you through some of the notable achievements.
Timely (and Stateful) Processing with Apache Beam
Kenneth Knowles
In a prior blog post, I introduced the basics of stateful processing in Apache Beam, focusing on the addition of state to per-element processing. So-called timely processing complements stateful processing in Beam by letting you set timers to request a (stateful) callback at some point in the future.
What can you do with timers in Beam? Here are some examples:
You can output data buffered in state after some amount of processing time. You can take special action when the watermark estimates that you have received all data up to a specified point in event time. You can author workflows with timeouts that alter state and emit output in response to the absence of additional input for some period of time. These are just a few possibilities. State and timers together form a powerful programming paradigm for fine-grained control to express a huge variety of workflows. Stateful and timely processing in Beam is portable across data processing engines and integrated with Beam’s unified model of event time windowing in both streaming and batch processing.
Powerful and modular IO connectors with Splittable DoFn in Apache Beam
Eugene Kirpichov
One of the most important parts of the Apache Beam ecosystem is its quickly growing set of connectors that allow Beam pipelines to read and write data to various data storage systems (“IOs”). Currently, Beam ships over 20 IO connectors with many more in active development. As user demands for IO connectors grew, our work on improving the related Beam APIs (in particular, the Source API) produced an unexpected result: a generalization of Beam’s most basic primitive, DoFn.
Apache Beam publishes the first stable release
Davor Bonaci &
Dan Halperin
The Apache Beam community is pleased to announce the availability of version 2.0.0. This is the first stable release of Apache Beam, signifying a statement from the community that it intends to maintain API stability with all releases for the foreseeable future, and making Beam suitable for enterprise deployment.
Python SDK released in Apache Beam 0.6.0
Ahmet Altay
Apache Beam’s latest release, version 0.6.0, introduces a new SDK – this time, for the Python programming language. The Python SDK joins the Java SDK as the second implementation of the Beam programming model.
Stateful processing with Apache Beam
Kenneth Knowles
Beam lets you process unbounded, out-of-order, global-scale data with portable high-level pipelines. Stateful processing is a new feature of the Beam model that expands the capabilities of Beam, unlocking new use cases and new efficiencies. In this post, I will guide you through stateful processing in Beam: how it works, how it fits in with the other features of the Beam model, what you might use it for, and what it looks like in code.
Note: This post has been updated in May of 2019, to include Python snippets!
Media recap of the Apache Beam graduation
Davor Bonaci
One year ago today Apache Beam was accepted into incubation at the Apache Software Foundation. The community’s work over the past year culminated, just over three weeks ago, with an announcement that Apache Beam has successfully graduated as a new Top-Level Project at the foundation. Graduation sparked an additional interest in the project, from corporate endorsements, news articles, interviews, to the volume of traffic to our website and mailing lists.
Apache Beam established as a new top-level project
Davor Bonaci
Today, the Apache Software Foundation announced that Apache Beam has successfully graduated from incubation, becoming a new Top-Level Project at the foundation and signifying that its “community and products have been well-governed under the foundation’s meritocratic process and principles”.

With initial code drops complete (Dataflow SDK and Runner, Flink Runner, Spark Runner) and expressed interest in runner implementations for Storm, Hadoop, and Gearpump (amongst others), we wanted to start addressing a big question in the Apache Beam (incubating) community: what capabilities will each runner be able to support?

Dataflow Python SDK is now public!

When the Apache Beam project proposed entry into the Apache Incubator the proposal included the Dataflow Java SDK. In the long term, however, Apache Beam aims to support SDKs implemented in multiple languages, such as Python.

Apache Beam has a logo!
James Malone
One of the major benefits of Apache Beam is the fact that it unifies both both batch and stream processing into one powerful model. In fact, this unification is so important, the name Beam itself comes from the union of Batch + strEAM = Beam
When the project started, we wanted a logo which was both appealing and visually represented this unification.
