Re: Multilang Support on Flink

Hi Welly, There is a protocol for communicating with other processes. This is reflected in flink-language-binding-generic module. I'm not aware how Spark or Storm communication protocols work but this protocol is rather low level. Cheers, Max On Fri, Nov 13, 2015 at 9:49 AM, Welly Tambunan

Hi rss rss, Yes. I have already read that book. However given the state of streaming right now, and Kappa Architecture, I don't think we need Lambda Architecture again ? Any thoughts ? On Thu, Nov 12, 2015 at 12:29 PM, rss rss wrote: > Hello, > > regarding the Lambda

Hi Arnaud, I'm happy that you were able to resolve the issue. If you are still interested in the first approach, you could try some things, for example using only one slot per task manager (the slots share the heap of the TM). Regards, Robert On Fri, Nov 13, 2015 at 9:18 AM, LINZ, Arnaud

Hello World Flink 0.10

Hi guys, I was trying to implement Hello World from slide 36 from http://www.slideshare.net/FlinkForward/k-tzoumas-s-ewen-flink-forward-keynote but I have problem with EOFTrigger - is it something I should implement by myself? I cannot find it in Flink libraries. Cheers, Kamil

Hi Kamil, The EOFTrigger is not part of Flink. However, I've also tried implementing the Hello World from the presentation here: https://github.com/rmetzger/scratch/blob/flink0.10-scala2.11/src/main/scala/com/dataartisans/Job.scala Stephan Ewen told me that there is a more elegant way of

Re: local debug Scala

This issue occurs when Flink has been build against another major scala release. Did you build Flink yourself or download it from somewhere (maven central) ? -- View this message in context: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/local-debug-Scala-tp1764p3481.html

Hi Robert, Thanks, it works with 50% -- at least way past the previous crash point. In my opinion (I lack real metrics), the part that uses the most memory is the M2 mapper, instantiated once per slot. The most complex part is the Sink (it does use a lot of hdfs files, flushing threads etc.) ;
