Re: Suppressing redundant KTable forwards

2016-12-04 Thread Mathieu Fenniak
Hi Eno, I'm not sure. My understanding is that the cache would prevent two immediate updates for the same key from being forwarded, but that only applies when records arrive within commit.interval.ms of each other. Is that understanding correct? filterRedundant compares the newValue & oldValue

A couple of remaining questions: - it says in the KIP: "because the metadata topic must be consumed by all instances, we need to assign the topic’s partitions manually and do not commit offsets -- we also need to seekToBeginning() each time we consume the metadata topic)" . How big of a change

Hi Mathieu, You are correct in that the de-duping only occurs within the commit interval. I can understand and appreciate the use-case you have. So I think the right approach for this is to create a KIP with your suggested changes and put it to the community. Are you happy to do that? Thanks,

Hi Apurva, Thanks for taking the time to reply. You make excellent points, and it sounds like the right tradeoff. It would be great if the coordinator code could be shared with the consumer API, hope that's actually the case. Daniel Schierbeck On Thu, 1 Dec 2016 at 18.34 Apurva Mehta
