Mysql-udf-http Efficiency Test note

I can see the post on "http/rest client" on the blog of Zhang banquet. I will skip all the installation steps. Next I will go directly to the test stage: virtual machine.

Table structure used:
Copy codeThe Code is as follows:
Drop table if exists 'mytable ';
Create table 'mytable '(
'Id' int (10) not null AUTO_INCREMENT,
'Addtime' int (10) not null,
'Title' varchar (255) not null,
Primary key ('id ')
) ENGINE = MyISAM default charset = utf8;

Php MySQL Operations Program:
Copy codeThe Code is as follows:
<? Php
$ Type = $ _ GET ['type'];
Print_r ($ _ GET );
Include_once ("gettime. php ");
$ Btime = getmicrotime ();
$ Loop_cnt = 1000; // number of cycles
$ Db_host = '2017. 0.0.1 ';//
$ Db_user = 'suns ';//
$ Db_pass = '20140901 ';//
$ Db_name = 'test ';//
$ Db_link = mysql_connect ($ db_host, $ db_user, $ db_pass) or die ("Connected failed:". mysql_error (). "\ n ");
Mysql_query ('set names utf8 ');
Mysql_db_query ($ db_name, $ db_link );
If ("put" = $ type) {// modify
$ I = 1;
While ($ I <= $ loop_cnt ){
$ Title = "jkjkjkjkjkjkjkjkjkjkjkjk ";
$ Tt = time ();
$ SQL = "update mytable set addtime =". $ tt. ", title = '". $ title. "'where id ='". $ I ."'";
$ Res = mysql_query ($ SQL );
If (FALSE = $ res ){
Echo "update failed! \ N ";
}
$ I ++;
}
} Else if ("delete" = $ type) {// delete
$ I = 1;
While ($ I <= $ loop_cnt ){
$ SQL = "delete from mytable where id = '". $ I ."'";
Echo "delete SQL:". $ SQL. "<br> ";
$ Res = mysql_query ($ SQL );
If (FALSE = $ res ){
Echo "delete failed! \ N ";
}
$ I ++;
}

} Else if ("post" ==$ type) {// Add
$ I = 0;
While ($ I <$ loop_cnt ){
$ Title = "hahahahahahahahahahahahahahahahahaha ";
$ Tt = time ();
$ SQL = "insert into mytable (addtime, title) values ($ tt, '". $ title ."')";
// Print "SQL:". $ SQL. "<br> ";
$ Res = mysql_query ($ SQL );
If (FALSE = $ res ){
Echo "insert failed! \ N ";
}
$ I ++;
}
}
Mysql_close ();
$ Etime = getmicrotime ();
$ RunTime = round ($ etime-$ btime, 4 );
Echo "runTime:". $ runTime. "\ r \ n <br> ";
?>

Execute php to connect to MySQL separately, and add 1000 records for a single connection: About S
Php program for memcache operations:
Copy codeThe Code is as follows:
<? Php
Include_once ("gettime. php ");
$ Btime = getmicrotime ();
// Zookeeper APIs
$ Mem_host = "192.168.0.134 ";
$ Mem_port = "11311 ";
$ Timeout = 3600;
$ I = 0;
$ Cnt = 1000;
While ($ I <$ cnt ){
$ Mem = new Memcache;
$ Mem-> connect ($ mem_host, $ mem_port) or die ("cocould not connect! ");
$ Ret = $ mem-> set ($ I, "11111111111", 0, $ timeout );
If (false = $ ret ){
File_put_contents ("insert_failed.log", "post failed! \ N ", FILE_APPEND );
}
$ Mem-> close ();
$ I ++;
}

// Skip
$ Etime = getmicrotime ();
$ RunTime = round ($ etime-$ btime, 4 );
Echo "runTime:". $ runTime. "\ r \ n <br> ";
?>

Add 1000 records for a single connection, which takes about seconds,
Create a trigger:
Copy codeThe Code is as follows:
DELIMITER $
Drop trigger /*! 50032 if exists */'test'. 'mytable _ insert' $
CREATE
/*! 50017 DEFINER = 'root' @ 'localhost '*/
TRIGGER 'mytable _ insert' AFTER insert ON 'mytable'
FOR EACH ROW BEGIN
SET @ tt_resu = (SELECT http_put (CONCAT ('HTTP: // 192.168.0.134/mem_ss.php? Type = post & id = ', NEW. id, "& data =", NEW. addtime), 11 ));
END;
$

Write a php update memcache for the trigger. The Code is as follows:
Copy codeThe Code is as follows:
<? Php
$ Id = $ _ GET ['id'];
$ Type = $ _ GET ['type'];
$ Json_data = $ _ GET ['data'];
Var_dump ($ _ GET );
// Zookeeper APIs
$ Mem_host = "192.168.0.134 ";
$ Mem_port = "11211 ";
$ Timeout = 3600;
$ Mem = new Memcache;
$ Mem-> connect ($ mem_host, $ mem_port) or die ("cocould not connect! ");
If ("get" = $ type ){
$ Val = $ mem-> get ($ id );
Echo $ val;
// $ Arr = jsonDecode ($ val, 'utf-8 ');
// Print_r ($ arr );
} Else if ("put" ==$ type ){
$ Ret = $ mem-> replace ($ id, $ json_data, 0, $ timeout );
If (false = $ ret ){
File_put_contents ("replace_failed.log", "replace failed! \ N ", FILE_APPEND );
}
} Else if ("delete" ==$ type ){
$ Ret = $ mem-> delete ($ id );
If (false = $ ret ){
File_put_contents ("delete_failed.log", "delete failed! \ N ", FILE_APPEND );
}
} Else if ("post" ==$ type ){
$ Ret = $ mem-> set ($ id, $ json_data, 0, $ timeout );
If (false = $ ret ){
File_put_contents ("post_failed.log", "post failed! \ N ", FILE_APPEND );
}
}
$ Mem-> close ();
?>

Use php to trigger MySQL to add 1000 records, and trigger php to update memcache, which takes about 9 s,
Because memcache links are closed every time, it is slow to see if the link is closed, and another program is written:
Copy codeThe Code is as follows:
<? Php
Include_once ("gettime. php ");
$ Btime = getmicrotime ();
// Connection
$ Mem_host = "192.168.0.134 ";
$ Mem_port = "11311 ";
$ Timeout = 3600;
$ I = 0;
$ Cnt = 1000;
While ($ I <$ cnt ){
$ Mem = new Memcache;
$ Mem-> connect ($ mem_host, $ mem_port) or die ("cocould not connect! ");
$ Ret = $ mem-& gt; set ($ I, "11111111111", 0, 3600 );
If (false = $ ret ){
File_put_contents ("insert_failed.log", "post failed! \ N ", FILE_APPEND );
}
$ Mem-> close ();
$ I ++;
}
// Close the connection
$ Etime = getmicrotime ();
$ RunTime = round ($ etime-$ btime, 4 );
Echo "runTime:". $ runTime. "\ r \ n <br> ";
?>

It takes about 0.9s and is not much slower than a connection.
Create a temporary table to locate whether the trigger is slow or http_put is slow.
Tmp_mytable. The table structure is as follows:
Copy codeThe Code is as follows:
Create table 'mytable '(
'Id' int (10) not null AUTO_INCREMENT,
'Addtime' int (10) not null,
'Title' varchar (255) NOT NULL
) ENGINE = MyISAM default charset = utf8;

Modify the trigger again as follows:
Copy codeThe Code is as follows:
DELIMITER $
Drop trigger /*! 50032 if exists */'test'. 'mytable _ insert' $
CREATE
/*! 50017 DEFINER = 'root' @ 'localhost '*/
TRIGGER 'mytable _ insert' AFTER insert ON 'mytable'
FOR EACH ROW BEGIN
Insert into tmp_mytable values (NEW. id, NEW. addtime, NEW. title );
END;
$

Using php again to add 1000 records to MySQL, which takes about S, proves that the efficiency consumption is http_put, that is, mysql-udf-http is slow.
I don't know if my test is wrong? You can also use the mysql-udf-http master, or have some knowledge about mysql-udf-http.
