Parth Brahmbhatt commented on KAFKA-2587:
-----------------------------------------
Hey Ismael,
As mentioned above, in production given all notifications will be processed
sequentially and as part of each notification we read the acls from zookeeper
(source of truth) this issue should not happen in production as long as
zookeeper guarantees read after write consistency. We may run into this issue
in the case where we observe inconsistency due to zookeeper not supporting
"Simultaneously Consistent Cross-Client Views". Please see Notes section in
http://zookeeper.apache.org/doc/trunk/zookeeperProgrammers.html#ch_zkGuarantees.
I looked at the zkClient code to see if we can call sync before read to avoid
any consistency concerns but zkClient does not support sync.
