Re: KTable Suppress not working

2020-01-20 Thread Sachin Mittal
Hi, As far as my understanding goes, aggregated result for a window is not included in next window. Window would stay in state store till it gets deleted based on certain setting however aggregated result for that window will include only the records that occur within the window duration. If you

Re: KTable Suppress not working

Thanks John. That partially answers my question. I'm a little confused about when a window will expire. As you said, I will receive at most 20 events at T2 but as time goes on will the data from the first window always be included in the aggregated result? On Mon, Jan 20, 2020 at 7:55 AM John

Re: Does Merging two kafka-streams preserve co-partitioning

Thanks John! I don't think transformValues will work here because I need to remove records which already have manual data? Either way it doesn't matter too much as I just write them straight to kafka. Thanks for your help! On Mon, Jan 20, 2020 at 4:48 PM John Roesler wrote: > Hi Yair, > >

Hi, Your approach is correct. For minor version upgrade (0.11.0.0 to 0.11.0.3), we can just update the brokers to new version. Thanks, On Mon, Jan 20, 2020 at 1:27 AM Sarath Babu wrote: > Hi all, > Appreciate any help/ pointers on how to upgrade.One thought is to start > the cluster brokers
