• Non-existing partitions missing from response when auto creation not enabled in the request
• Check and act is not safe when inserting into inflight map
• Change value type of inflight map to Boolean since we don't need the value
• Set timeout of 0 in the call to ZkAdminManager.createTopics since we don't need to wait for full creation
• Fix log message which suggests that creation through ZkAdminManager is asynchronous
• Clean up error message when the number of live brokers is insufficient for the replication factor
• Reuse value of MetadataCache.aliveBrokers rather than recomputing for every partition
• Controller mutation quota was not setting version correctly. Fixed to use permissive quota which is consistent with current behavior
