hi john
in our experience , the checkpoint interval we set interval 1-10 minute and
timeout usurally 5*interval . mostly we set 2 or 5 minute and 10 or
20timeout.
it depend on u data bulk per second and which window used.

I'm running Flink 1.7.2 in a Docker swarm. Intermittently, new task managers
will fail to resolve their own host names when starting up. In the log I see
"no hostname could be resolved" messages coming from TaskManagerLocation. The
webUI on the jobmanager shows the taskmanagers as are
Hi, using Flink 1.8.0
1st off I must say Flink resiliency is very impressive, we lost a node and
never lost one message by using checkpoints and Kafka. Thanks!
The cluster is a self hosted cluster and we use our own zookeeper cluster.
We have...
3 zookeepers: 4 cpu, 8GB (each)
3 job nodes: 4
Hi Kostas,
Thank you for the answer and clarification.
If Side-outputs are treated in the same way and there is no significant
performance penalty then it seems that they are ok for my use case.
I can accept the name mismatch ;)

hi 大家好:
最近有在调研使用flink做实时数仓,但是有个问题没弄清楚,就是明细表和维度表做join的时候,该采取什么的方案?目前的想到的就是明细表通过流消费进来,维度表放缓存。但是这种方案有弊端,就是维度表更新后,历史join过的数据无法再更新。不知道大家还有什么其他的方案?ps:目前有看到flink有支持join,这种需要两个表都是流的方式进入flink,然后会将历史的数据保存在state里面,这种对于量大的表会不会有问题?
Okay, I understand. I'm okay with removing the profile.

Hi Krzysztof,
If I get it correctly, your main reason behind not using side-outputs
is that it seems that "side-output", by the name, seems to be a
"second class citizen" compared to the main output.
I see your point but in terms of functionality, there is no difference
between the different
Hi
这个异常是因为无法绑定随机端口,在出问题的JM机器上检查一下
netstat,看是不是有大量的连接占用了很多端口。一般这种问题都是因为大量对外连接未关闭导致的,找到是什么类型的进程占用了大量端口。
祝好
