Is there any good documentation on building a flink source connector. I need to
build on for AMPS.

I think you should upgrade Linux to said version or newer.

my flink veriso is 1.4.2
my jdk version is 1.8.0.20
my linux version is:3.10.0
I try to use epoll with setting: tasker.network.netty.transport: epoll
but it throws excption which leads me here:

I followed the instruction and still exception throws.
Hi Daniel,
The discussion for releasing Flink 1.4.3 hasn't been started (until now).
The community is still working on the 1.5.0 release but AFAIK, there are no
blockers for 1.4.3.
Development and release discussions take place on the dev@f.a.o list.
Would you kicking off a discussion there?

That is only used to split the load across all of the subtasks, which am
already doing.
It is not related with the allocation.

Hi,
We put a lot of logging in our code the flow of events as they flow
between operators,
this is done at the DEBUG level.
Normally this logging would be turn off by setting the logging level to
INFO or above,
because logging everything is expensive and a cluttered log is harder to
analy
Hi,
I'm trying to run a program by sending POST requests.
I've already spawned dispatcher in YARN and uploaded a jar file to the
dispatcher.
I want to execute my application using the following arguments (--topic and
--kafkaParams):
--topic gps-topic --kafkaParams
bootstrap.servers=dac
Hi Gary,
This setting has resolved the issue. Does it increase timeout for all the
RPC or specific components?
We had following settings in Flink 1.3.2 and they did the job for us.
akka.watch.heartbeat.pause: 600 s
akka.client.timeout: 5 min
akka.ask.timeout: 120 s

If estimates are good enough, we should be able to expose something. Would
still like to double check the guarantees to see if the estimates of RocksDB
are helpful or could be misleading.

Thanks. At least for us it doesn't matter how exact the number is. I would
expect most users to be only interested in monitoring if the total state
size keeps growing (rapidly), or remains about the same. I suppose all of
the options that you suggested would satisfy this need?

I wonder if comparing the size of a full checkpoint vs total size of an
incremental checkpoint to get insights about the keycount is helpful at all
because:
- Full checkpoints are basically a dump of all key value pairs as written by
their serializers, plus their keygoup id. Each key is contain
Hi,
I have a doubt about Flink operators implementation and I am trying to
search some link on the internet about this
Do the operators in Flink are compiled and fused at runtime? Do you guys
have a link that can explain to me how it is implemented in Flink?
Kind Regards,
Felipe

Hi Makeyang,
Would you mind opening a JIRA issue [1] for your improvement suggestion?
It would be good to add the Flink version that you are running.
Thanks, Fabian

Hi,
for incremental checkpoints, it is only showing the size of the deltas. It
would probably also be possible to report the full size, but the current
reporting and UI is only supporting to deliver a single value. In general, some
things are rather hard to report. For example, for the heap bas
Hi Aljoscha & co.,
Is there any way to monitor the state size yet? Maybe a ticket in Jira?
When using incremental checkpointing, the total state size can't be seen
anywhere. For example the checkpoint details only show the size of the
increment. It would be nice to add the total size there as wel
Hi Petter,
which state backend are you using in your case? I think there is no
quick solution for your problem because a proper schema evolution story
is on the roadmap for Flink 1.6.
Would it work to change the serial version id of the generated Avro
class as a temporary workaround?

Great! Thanks Gary

Hi David,
You are right. If you don't use start-cluster.sh, the conf/masters file is
not
needed.
