[ANNOUNCE] New Flink community mailing list

2016-12-14 Thread Kostas Tzoumas

Hi everyone,

We have created a new Flink mailing lists, commun...@flink.apache.org where
we can post everything related to the broader Flink community including job
offers, upcoming meetups and conferences, exciting reads, and everything
else that is deemed worthy for the greater Flink community. We will be
running a monthly "Who's hiring" thread there for job positions on Flink.

The scope of this list is restricted to Flink-related content, i.e., please
do not post content or job offers on Big Data in general.

You can subscribe to this list as usual by sending an email to

community-subscr...@flink.apache.org

We will be adding this list to the Flink website soon.

Best,
Kostas

2016-12-09 Thread Kostas Tzoumas

I appreciate the concern Kanstantsin!

We do have a news@ mailing list, but it has been under-utilized so far.
Perhaps revamping that one would do it?

My only concern is that subscribing to a new mailing list is an overhead.
As a temp solution, we could cc the dev and user list in the first few
(say, 3) threads and encourage folks in these threads to sign up for the
news@ list.

[DISCUSS] "Who's hiring on Flink" monthly thread in the mailing lists?

2016-12-06 Thread Kostas Tzoumas

Hi folks,

I'd like to see how the community feels about a monthly "Who is hiring on
Flink" email thread on the dev@ and user@ mailing lists where folks can
post job positions related to Flink.

I personally think that posting individual job offerings in the mailing
list is off-topic (hence I have refrained to do that wearing my company
hat, and I have discouraged others when they asked for my opinion on this),
but I thought that a monthly thread like this would be both helpful to the
community and not cause overhead.

[ANNOUNCE] Flink Forward 2016: First round of speakers and sessions is out

2016-07-25 Thread Kostas Tzoumas

Hi everyone,

I wanted to share this with the community: we have announced the first
round of speakers and sessions of Flink Forward 2016, and it looks amazing!

Check it out here: http://flink-forward.org/program/sessions/

This year we have a great mix of use case talks (e.g., by Netflix, Alibaba,
Intel, Cisco, King, Zalando, etc), in-depth developer-oriented talks on
Flink existing and upcoming features by committers and contributors, and
several talks on the wider stream processing landscape, including Apache
Beam (incubating), streaming SQL, and more.

As a reminder, the last day for early bird tickets is this Sunday, July 31.
I'm really looking forward to seeing as many of us there as possible!

Best,
Kostas

Re: About exactly once question?

2015-08-27 Thread Kostas Tzoumas

Note that the definition of exactly-once means that records are
guaranteed to be processed exactly once by Flink operators, and thus state
updates to operator state happen exactly once (e.g., if C had a counter
that x1, x2, and x3 incremented, the counter would have a value of 3 and
not a value of 6). This is not specific to Flink, but the most accepted
definition, and applicable to all stream processing systems. The reason is
that the stream processor cannot by itself guarantee what happens to the
outside world (the outside world is in this case the data sink).

See the docs (
https://ci.apache.org/projects/flink/flink-docs-master/internals/stream_checkpointing.html
):

Apache Flink offers a fault tolerance mechanism to consistently recover
the state of data streaming applications. The mechanism ensures that even
in the presence of failures, the program’s state will eventually reflect
every record from the data stream exactly once.

Guaranteeing exactly once delivery to the sink is possible, as Marton above
suggests, but the sink implementation needs to be aware and take part in
the checkpointing mechanism.

Dear Zhangrucong,

From your explanation it seems that you have a good general understanding
of Flink's checkpointing algorithm. Your concern is valid, by default a
sink C with emits tuples to the outside world potentially multiple times.
A neat trick to solve this issue for your user defined sinks is to use the
CheckpointNotifier interface to output records only after the corresponding
checkpoint has been totally processed by the system, so sinks can also
provid exactly once guarantees in Flink.

This would mean that your SinkFunction has to implement both the
Checkpointed and the CheckpointNotifier interfaces. The idea is to mark the
output tuples with the correspoding checkpoint id, so then they can be
emitted in a consistent manner when the checkpoint is globally
acknowledged by the system. You buffer your output records in a collection
of your choice and whenever a snapshotState of the Checkpointed interface
is invoked you mark your fresh output records with the current
checkpointID. Whenever the notifyCheckpointComplete is invoked you emit
records with the corresponding ID.

Note that this adds latency to your processing and as you potentially need
to checkpoint a lot of data in the sinks I would recommend to use a HDFS as
a state backend instead of the default solution.

Best,

Marton

Hi:

The document said Flink can guarantee processing each tuple
exactly-once, but I can not understand how it works.

For example, In Fig 1, C is running between snapshot n-1 and snapshot
n(snapshot n hasn’t been generated). After snapshot n-1, C has processed
tuple x1, x2, x3 and already outputted to user, then C failed and it
recoveries from snapshot n-1. In my opinion, x1, x2, x3 will be processed
and outputted to user again. My question is how Flink guarantee x1,x2,x3
are processed and outputted to user only once?

Re: CoGgroup Operator Data Sink

2015-04-14 Thread Kostas Tzoumas

Each operator has only one output (which can be consumed by multiple
downstream operators), so you cannot branch out to two different directions
from inside the user code with many collectors. The reasoning is that you
can have the same effect with what Robert suggested.

But perhaps your use case is different; can you not achieve the same result
with branching out to two different DataSets as per Robert's suggestion? If
this is the case, posting some details on the function would be helpful.

 Maybe the expression Sink is not suitable to what I need. What if I want

 anyway to do so ?!!

 As I might know, the operator has only Collector Object, but I wonder if
 there is another feature in Flink that supports what I need .

 Thanks.

 Hi,

 you can write the output of a coGroup operator to two sinks:

 --\   /Sink1
\ /
 (CoGroup)
/\
 --/  \--Sink2

 You can actually write to as many sinks as you want.
 Note that the data written to Sink1 and Sink2 will be identical.
 If you want to write different data to S1 and S2, you can use a Tuple2
 where the first field contains a tag, and the second field contains your
 data.
 Then, you use a filter in front of your Sinks to select the data based on
 the tag.

 --\   /---(Filter)--Sink1
\ /
 (CoGroup)
/\
 --/  \(Filter)--Sink2

 So the output of CoGroup could be Tuple2Integer,YourPojo, when the
 integer is 1, it is only written by Sink1, when the integer is 2, its only
 written by Sink2.

Flink Forward 2015

2015-04-07 Thread Kostas Tzoumas

Hi everyone,

The folks at data Artisans and the Berlin Big Data Center are organizing
the first physical conference all about Apache Flink in Berlin the coming
October:

http://flink-forward.org

The conference will be held in a beautiful spot an old brewery turned event
space (the same space that Berlin Buzzwords took place last year). We are
soliciting technical talks on Flink, talks on how you are using Flink to
solve real world problems, as well as talks on Big Data technology in
general that relate to Apache Flink's general direction. And of course,
there will be enough social and networking events to get the community
together :-)

The website and the call for abstracts are live, but the ticket
registration is not yet open.

At this point, I would like to ask the community to mark your calendars if
you'd like to attend, submit an abstract, and forward the event to your
friends and family. If you can help us market the event, help in any other
way, or have any other inquiries, please get in touch with me!

I will also announce this via our social media channels this week.

I am looking forward to gathering the community in a great conference!

Best,
Kostas
