This seems a great example of use of stateful DoFn. It has essentially the
same structure as the example on the Beam blog but is more meaningful.

OK, the only way to do this would be via a non-determanistic stateful
DoFn that buffers elements as they come in and computes averages by
looking at the buffer each time.
This could also be represented with an extension to window merging and
a join, where the trigger would be explicitly used to
These can be externalized as PTransforms. E.g. the generic ETL
pipeline could just be written
pipeline
.appy(SomeExtractPTransform()) // aka Source
.apply(SomeTransformPTransform())
.apply(SomeLoadPTransform()) // aka Sink
Any and all of these PTransforms may be composite (i.e
The real benefit of a good ETL framework is being able to externalize your
extraction and transformation mappings. If I didn't have to write that
part, that would be really cool!

I would like to call out that Beam itself can be directly used for
ETL, no extra framework required (not to say that both of these
frameworks don't provide additional value, e.g. GUI-style construction
of pipelines).

Hello! Talend has a big data ETL product in the cloud called Pipeline
Designer, entirely powered by Beam. There was a talk at Beam Summit
2018 (https://www.youtube.com/watch?v=1AlEGUtiQek), but unfortunately
the live demo wasn't captured in the video. You can find other videos
of Pipeline
Many thanks for your ideas, everybody, I really appreciate it. I’m going to
play with Stateful DoFn and see if it will work for us.

Answering your question, Kenn. Yes, potentially, we can build indices for

Nice, thanks. I just registered, see you there !

Hi Pierre,

Hi Pierre,
If you are in Paris region (I can guess because of Dailymotion name =) ) then
it would be great to chat about that at next (2nd) Paris Beam meetup, which
will be held very soon, October 17th.

Thanks Etienne & Matthias !
Why not, it kinda depends on the location :) What meetup / summit do you have
in mind ?

Thank you for your reply. I will check it out! I'm in the evaluation
phase, especially since I have some time before I have to implement all of
this.

Great writeup. You can add an additional benefit of docker vs templates:
Dynamically reconfigure/rebuild your pipelines from external parameters
(example arguments), iso only using the Value placeholders.

This is great, Pierre! Thank you for sharing, very interesting.
Would you and your team be interested to talk about your use case at a
meetup (or Summit) in the future? :)
All the best,
Matthias

Depends on your use case but kettle rocks for etl.
