Subject Re: [Discuss] Samza 0.14.1 release
Date Mon, 30 Apr 2018 22:18:10 GMT
These all look like excellent changes to me, I'd be happy to have more
stability in Standalone!
Any timeline on getting Kafka 0.11 upgrade in? It seems to have been
done a while, but waiting for 0.15 I presume.
Best,

Tom
