Subject [DISCUSS] ACL operations
Date Thu, 13 Apr 2017 21:21:06 GMT
Hi all,

KIP-4 described some RPCs for implementing centralized administrative
operations for Kafka.  Now that the adminclient work is going forward,
I'd like to re-open the discussion about the ACL-related RPCs.  This is
a continuation of the email thread Grant Henke started while back.  (See 
http://search-hadoop.com/m/Kafka/uyzND18EGG22cFMXg?subj=+DISCUSS+KIP+4+ACL+Admin+Schema
)

I think the idea of sending a batch of ACL-related operations all at
once is good for efficiency.  However, I wonder if it is simpler to
separate the add and remove ACLs operations, or if we really ought to
combine them into one RP  It seems that when both add and remove
operations are combined into one RPC, there are some thorny questions
about ordering (does a delete ACL operation on a topic happen first, or
an add ACL operation?)

best,
Colin
