In PHP foreach, you need to pay attention to a problem and a solution when using references. I. first look at an example :? Php $ ararray (1, 2, 3); var_dump ($ ar); foreach ($ aras? Output: array (3) {[0] int (1) [1] int (2) [2] int (3)} array (3) {[0] int (1)
I. problemsLet's take a look at an example:
$ Ar = array (1, 2, 3 );Var_dump ($ ar );Foreach ($
available brokers from all replica (called AR) assigned to the partition as the new leader and set AR as the new ISR (because the topic is newly created, so all replica in AR have no data, It can be thought that they are all synchronous, that is, all in the ISR, any one of the replica can be used as leader)3.2 Write the new leader and ISR/brokers/topics/[topic]/

For the delete topic operation, the topic tool will save the topic name in the /admin/delete_topics . If delete.topic.enable true, /admin/delete_topics watch on which the controller is registered is sent b
