Hey nuno! Welcome to the Flink community. :) The points you mentioned sound
very reasonable. There is also a how to contribute guide and a coding
guidelines document on the web page you can check out. Is there a specific
starter issue you are interested in? Then it will be easier to give

Hey Tran Nam-Luc,
You don't have to register with a serializer. Can you share the event code?
I will look into it asap.
The runtime is buffer oriented and events arrive as buffers before they are
deserialized. That's why you see the getNextBuffer call in the stack trace.

Out of order is ubiquitous in the real-world. Typically, what happens is
that businesses will declare a maximum allowable delay for delayed
transactions and will commit to results when that delay is reached.
Transactions that arrive later than this cutoff are collected specially as

Hello everyone,
I am a new contributor (well soon to be!) to this project and I am just
getting to know the ropes around the framework.
I love what flink is about which is what makes me want to contribute to
it.
I have read the documentation and will still re-read it a couple more
times. I
I also don't like big changes but sometimes they are necessary. The reason
why I'm so adamant about out-of-order processing is that out-of-order
elements are not some exception that occurs once in a while; they occur
constantly in a distributed system. For example, in this:

Hi everyone,
With the vote now being passed, we should think about the release
announcement. I've created a document which basically contains the
milestone release announcement with a few changes.

What I like a lot about Aljoscha's proposed design is that we need no
different code for "system time" vs. "event time". It only differs in where
the timestamps are assigned.
The OOP approach also gives you the semantics of total ordering without
imposing merges on the streams.

@Stephan I understand your concerns that the user might wonder that nothing
happens when executing. However, in this case a warning will provide a hint
to the user that he didn't define any sinks. In the case where he
immediately calls execute() after an eager execution, the program is
actually exe
Hi!
On Travis, there seems to be the weird issue that the file writing in the
tests is not completely reliable. Sometimes the test results are read from
incomplete/stale files.
I lazily try to migrate failed tests to using "collect()". This seems
reliable on Travis.
Cheers,

I agree that there should be multiple alternatives the user(!) can
choose from. Partial out-of-order processing works for many/most
aggregates. However, if you consider Event-Pattern-Matching, global
ordering in necessary (even if the performance penalty might be high).
I would also keep "system-t

That would help to get around many cases, it still leaves some open, like
forgetting to create a sink after transformations after a collect() call.
Would probably be a good improvement over the status quo, though...

Hey
I think we should not block PRs unnecessarily if your suggested changes
might touch them at some point.
Also I still think we should not put everything in the Datastream because
it will be a huge mess.
Also we need to agree on the out of order processing, whether we want it

For the windowing designs, we should also have in mind what requirements we

The reason I posted this now is that we need to think about the API and
windowing before proceeding with the PRs of Gabor (inverse reduce) and
Gyula (removal of "aggregate" functions on DataStream).
For the windowing, I think that the current model does not work for
out-of-order processing. Theref
