Morning

Morning!

This morning was about wrapping an API with a GraphQL endpoint (in CLJS of course), good fun.

working on uneffing entangled kafka topics, not much of clj involved 😕

beats trying to build a distribution 6 times till the local nexus finally has all the jar’s cashed..

nah.. just psql

@skuro you have any good tips on managing Kafka topics ? It seems to be some kind of black art that most people seem to be doing wrong.

@lmergen for now, apart from some minor replication tricks I think the best one is: always keep a kafka cluster ready for a full topic migration (e.g. with mirrormaker)

we had many cases in which topics would get hard stuck in some zombie mode (e.g. rolling upgrade of the brokers, topic fixated onto long-gone replicas, doesn't accept reassignment anymore)

right. so not doing any scary in-place upgrades, but treat the entire cluster as immutable. that’s usually a sane approach for most things, but it’s more costly to set up.
