> In Partition.createLog we do:
> {code:java}
> val config = LogConfig.fromProps(logManager.currentDefaultConfig.originals, props)
> val log = logManager.getOrCreateLog(topicPartition, config, isNew, isFutureReplica)
> {code}
> https://github.com/apache/kafka/blob/33d06082117d971cdcddd4f01392006b543f3c01/core/src/main/scala/kafka/cluster/Partition.scala#L315-L316
> Config changes that arrive after configs are loaded from ZK, but before LogManager added the partition to `futureLogs` or `currentLogs` where the dynamic config handlers picks up topics to update their configs, will be lost.
