redis-Transaction Transaction

The goal of Redis is to be concise and efficient, because the transaction itself is a complex thing, and all we can't do is complicate the transaction ...

  
 

   
  

  
 multi，exec
   
  

  

   
  

  
127.0.0.1:6379> multi 
   
  

  
OK
   
  

  
127.0.0.1:6379> lpush fruits orange
   
  

  
QUEUED
   
  

  
127.0.0.1:6379> lpush fruits nut
   
  

  
QUEUED
   
  

  
127.0.0.1:6379> lpush fruits apple
   
  

  
QUEUED
   
  

  
127.0.0.1:6379> exec
   
  

  
1) (integer) 1
   
  

  
2) (integer) 2
   
  

  
3) (integer) 3
  
 

The transaction does not support rollback in order to make redis simple enough, so be careful when writing code
Use watch to protect variables that don't want to be multi changed

  
 

   
  

  
127.0.0.1:6379> watch msg
   
  

  
OK
   
  

  
127.0.0.1:6379> multi
   
  

  
OK
   
  

  
127.0.0.1:6379> set msg "2008 hello wolrd"
   
  

  
QUEUED
   
  

  
127.0.0.1:6379> exec
   
  

  
(nil)
   
  

  
127.0.0.1:6379> get msg
   
  

  
"12345" // 没有被改变
   
  

  
127.0.0.1:6379>
