Hi Jose, Thanks for the KIP, looks valuable.
If I use a PreferredLeaderElection RPC to specifically request an unclean leader election, will this take effect even if unclean leader elections are disabled on the topic involved? I assume that the answer is yes, but it would be good to clarify this in the KIP. What ACLs will be required to perform this action? WRITE on the topic resource? Or ALTER on KafkaCluster? Or perhaps ALTER on the topic would be most appropriate, since we probably don't want ordinary producers triggering unclean leader elections. What's the rationale for using an int8 rather than just having a boolean that is either true or false for "unclean"? We only have two values now, and it seems like we could modify the RPC schema in the future if needed. Or is the intention to add more flags later? best, Colin On Wed, Apr 24, 2019, at 15:45, Jose Armando Garcia Sancio wrote: > Hi all, > > We would like to extend the "preferred leader election" RPC for the admin > client to also support unclean leader elections. > > The KIP can be found here: > https://cwiki.apache.org/confluence/display/KAFKA/KIP-460%3A+Admin+Leader+Election+RPC > > Thanks! > -Jose >
