Apache Beam’s primitives let you build expressive data pipelines, suitable for a variety of use cases. One specific use case is the analysis of time series data in which continuous sequences across window boundaries are important. A few fun challenges arise as you tackle this type of data and in this blog we will explore one of those in more detail and make use of the Timer API (blog post) using the “looping timer” pattern.

A new, exciting feature that came to Apache Beam is the ability to use
SQL in your pipelines. This is done using Beam’s
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.

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:
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.
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:
Keep an eye out for a meetup in Paris.
If you are interested in starting your own meetup, feel free to reach out! Good places to start include our Slack channel, the dev and user mailing lists, or the Apache Beam Twitter.
Even if you can’t travel to these meetups, you can stay informed on the happenings of the community. The talks and sessions from previous conferences and meetups are archived on the Apache Beam YouTube channel. If you want your session added to the channel, don’t hesitate to get in touch! And in case you want to attend the next Beam event in style, you can also order your swag on the Beam swag store
The first summit of the year will be held in Berlin:
You can find more info on the website and read about the inaugural edition of the Beam Summit Europe here. At these summits, you have the opportunity to meet with other Apache Beam creators and users, get expert advice, learn from the speaker sessions, and participate in workshops.
We strongly encourage you to get involved again this year! You can participate in the following ways for the upcoming summit in Europe:
🎫 If you want to secure your ticket to attend the Beam Summit Europe 2019, check our event page.

We are thrilled to announce the launch of our new website dedicated to Beam Summits!
The beamsummit.org site provides all the information you need towards the upcoming Beam Summits in Europe, Asia and North America in 2019. You will find information about the conference theme, the speakers and sessions, the abstract submission timeline and the registration process, the conference venues and hosting cities - and much more that you will find useful until and during the Beam Summits 2019.
We are working to make the website easy to use, so that anyone who is organizing a Beam event can rely on it. You can find the code for it in Github.
The pages will be updated on a regular basis, but we also love hearing thoughts from our community! Let us know if you have any questions, comments or suggestions, and help us improve! Also, if you are thinking of organizing a Beam event, please feel free to reach out for support, and to use the code in GitHub as well.
We sincerely hope that you like the new Beam Summit website and will find it useful for accessing information. Enjoy browsing around!
See you in Berlin!

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.

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:
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.

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,

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!

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.
Jan 10, 2017 • Davor Bonaci [@BonaciDavor]
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”.

It’s been just over six months since Apache Beam was formally accepted into incubation with the Apache Software Foundation. As a community, we’ve been hard at work getting Beam off the ground.
Jun 15, 2016 • Davor Bonaci [@BonaciDavor]
I’m happy to announce that Apache Beam has officially released its first version – 0.1.0-incubating. This is an exciting milestone for the project, which joined the Apache Software Foundation and the Apache Incubator earlier this year.

This morning, Eugene and Malo from the Google Cloud Dataflow team posted No shard left behind: dynamic work rebalancing in Google Cloud Dataflow. This article discusses Cloud Dataflow’s solution to the well-known straggler problem.
Are you interested in giving a presentation about Apache Beam? Perhaps you want to talk about Apache Beam at a local Meetup or a convention. Excellent! The Apache Beam community is excited to expand and grow the community. To help kickstart this process, we are excited to announce an initial set of Apache Beam presentation materials which anyone can use to give a presentation about Apache Beam.
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?

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.
