How To Install lua-resty-lrucache on Debian 12
Introduction
In this tutorial we learn how to install lua-resty-lrucache on Debian 12.
What is lua-resty-lrucache
lua-resty-lrucache is:
The LRU cache resides completely in the Lua VM and is subject to Lua GC. As such, do not expect it to get shared across the OS process boundary. The upside is that you can cache arbitrary complex Lua values (such as deep nested Lua tables) without the overhead of serialization (as with ngx_lua’s shared dictionary API). The downside is that your cache is always limited to the current OS process (i.e. the current Nginx worker process). It does not really make much sense to use this library in the context of init_by_lua because the cache will not get shared by any of the worker processes (unless you just want to “warm up” the cache with predefined items which will get inherited by the workers via fork()).
