redis lua performance

First, IntroductionRedis has been learning for a while, and the basics are all fine. Starting today to write about some of the things that are related to Redis and Lua scripting, the Lua script is a good thing that can be run on any platform or embedded in most languages to extend its functionality. The Lua script is w

When Lua executes the Redis command through the call () or Pcall () function, the return value of the command is converted to the LUA data structure. Similarly, when the Lua script runs in the Redis built-in interpreter, the return value of the

count;It is important to note that scenario two can be used as a way of thinking by combining the Redis built-in commands to implement commands for specific functions through LUA scripting. And here the Mode key bulk Delete is not a good command, because if the number of key is very large, there will be more serious performance problems.

StackExchange. Redis loads the Lua script for batch deletion and modification of fuzzy queries. stackexchange. redisPreface Use StackExchange. redis does not directly use related methods to batch delete or modify Fuzzy queries. Although you can use Scan-related methods to perform fuzzy queries, for example, HashScan ("hashkey ", "* key *"), and then use the relev
