Function Throttling principle:Set a timer settimeout, let the execution of the function delay a period of time before going to execute, if in this time, the function is triggered again, then clear the original settimeout, create a new settimeout, and so on, executed a function throttle.Function Encapsulation:1 function Throttle (method, context) {2 cleartimeout (method.tid); 3 Method.tid = SetTimeout (function() {4 method.call (context);

This parameter is used at backup time to output the Xtrabackup_logfile content to the standard output, and the Suspend-at-end parameter is used automatically when using this parameter, which is used by the Innobackupex script's stream mode.
Chinese characters in the actual development are actually caused by the transformation between the character stream and the word throttling.
When converting from byte to character stream, which is actually byte[] into a string,

There is a key parameter character set encoding, which is usually omitted, and the system uses the OS LangWhen a character is converted to a byte stream, it is actually a string that converts to byte[]Byte[

For users unfamiliar with the expected state configuration, the improved functionality allows administrators to compare the expected state of the Windows Server, and if the server has problems and deviates from the ideal configuration, the administrator can take corrective action in a timely manner.
