The author for Apache Beam A Complete Guide does not have good reviews on
Amazon for their other books and as you mentioned no reviews for this one.
I would second the Streaming Systems book as the authors directly worked on
Apache Beam.

Hi,
I am using Dataflow. When I update my DF job with a new topic or update
partition count on the same topic. I can not use DF's update function.
Could you help me to understand why I can not use the update function for
that ?
I checked the Beam source code but I could not find the right place t
The intent is that you grant permissions to the account that is running the
Dataflow job to the resources you want it to access in project B before you
start the pipeline. This allows for much finer grain access control and the
ability to revoke permissions without having to disable an entire accou
Yes, it’s a known limitation [1] mostly due to the fact that KafkaIO.Read is
based on UnboundedSource API and it fetches all information about topic and
partitions only once during a “split" phase [2]. There is on-going work to make
KafkaIO.Read based on Splittable DoFn [3] which should allow to
I don’t think it’s a known issue. Could you tell with version of Beam you use?

Thanks Alexey for sharing tickets and code. I found one workaround to use
the update function. If I generate different KafkaIO step name for each
submission and
provide
--transformNameMapping="{"Kafka_IO_3242/Read(KafkaUnboundedSource)/DataflowRunner.StreamingUnboundedRead.ReadWithIds":""}"

Hm it looks like the error is from trying to call the zero-arg constructor
for the ArticleEnvelope proto class. Do you have a schema registered for
ArticleEnvelope?
I think maybe what's happening is Beam finds there's no schema registered
for ArticleEnvelope, so it just recursively applies JavaFie
Thank you Luke. I changed DefaultTrigger.of() to AfterProcessingTime.
pastFirstElementInPane() and it worked.

It just occurred to me that BEAM-10265 [1] could be the cause of the stack
overflow. Does ArticleEnvelope refer to itself recursively? Beam schemas
are not allowed to be recursive, and it looks like we don't fail gracefully
for recursive proto definitions.

Hi Wesley,
In essence, yes, that’s what they did.
The three authors of Streaming Systems are folks that work on Google’s Dataflow
Project, which for all intents and purposes is essentially an implementation of
the Beam Model. Two of them are members of the Beam PMC (essentially a steering

Can you give context as to whether schemas will ever allow recursive types
since this is pretty common in lots of languages?
