Hi Matthias, Thanks for the feedback.
There is no outer-join for GlobalKTables as the tables may be keyed differently. So you need to use the key from the left side of the join along with the KeyValueMapper to resolve the right side of the join. This wont work the other way around. On the bootstrapping concern. If the application is failing before bootstrapping finishes, the problem is likely to be related to a terminal exception, i.e., running out of disk space, corrupt state stores etc. In these cases, we wouldn't want the application to continue. So i think this is ok. Thanks, Damian On Tue, 6 Dec 2016 at 21:56 Matthias J. Sax <matth...@confluent.io> wrote: > Thanks for the KIP Damian.
