[jira] [Created] (KAFKA-9932) First LeaderAndIsrRequest can take long due to unnecessary ZK read

Ismael Juma created KAFKA-9932:
----------------------------------

             Summary: First LeaderAndIsrRequest can take long due to unnecessary ZK read
                 Key: KAFKA-9932
                 URL: https://issues.apache.org/jira/browse/KAFKA-9932
             Project: Kafka
          Issue Type: Improvement
            Reporter: Ismael Juma
            Assignee: Ismael Juma


[~junrao] found the following issue:
{quote}In Partition, we have the following code. fetchLogConfig is passed in to logManager.getOrCreateLog by value. This can increase the processing time for the very first LeaderAndIsrRequest since every partition has to do a ZK read to load the log config. This is unnecessary if the log is always present and loaded during the initialization of LogManager.
