Opened a PR for this issue: https://github.com/apache/flink/pull/2766 To explain, the PR refactors the NettyClient/NettyServer to be reusable for the ever-growing set of endpoints within Flink. The procedure for defining an endpoint would now be: 1. Create a configuration subclass of `NettyCon

Re: Deterministic processing with out-of-order streams

Hi Jaromir, You can make use of Custom Trigger and set the allowed lateness to max value. I have kept the custom trigger code (EventTimeTrigger) same as Flink 1.0.3, doing this the late elements will not be discarded and they will be assigned single windows , now you can decide what you want to d

Re: Deterministic processing with out-of-order streams

You're right if you want to guarantee a deterministic computation for an arbitrary allowed lateness. In the general case, you would never be able to calculate the final result of a window in a finite time, because there might always be another element which arrives later. However, for most practica

Re: [FLINK-3035] Redis as State Backend

I didnt measure size, just with vs. w/out Redis made a day & night difference in performance so I replaced it with Java concurrent HM  objects.Still in progress as far as benchmarking. Have issues with tuning Flink for very high loads... You can see some of my communications with Aljoscha...Chee

Re: Deterministic processing with out-of-order streams

Hi Till, thank you for your answer. I am afraid defining an allowed lateness won't help. It will just change the problem by constant time. If we agree an element can come in arbitrary time after watermark (depends on the network latency), it may be assigned to the window or may be not if comes be

Re: Deterministic processing with out-of-order streams

Hi Jaromir, deterministic processing with late elements is indeed more difficult than without them. What you have to do is to send updates to your downstream operators in case that you see late elements. This can either be an incremental update or a retraction with the corrected value. It basicall

Re: Stream processing via Kafka using Android

Hi Artur, I'm not sure if Flink is the best tool to write data from Android Apps to Kafka. Flink would be a good choice to process such data by reading it from Kafka. I would reach out to the Kafka user list and seek for advice there. Best, Fabian Btw. The Apache dev@ mailing lists are meant to
