`multiple Apache APISIX instances` is not a problem here, the architecture diagram mainly describes the Redis side.
you can refer to the implement of the limit-count plugin[1], which is also supported Redis. I have one question: Is there a performance impact if you run Lua script in Redis? Can we run related Lua code in the Apache APISIX side, and only using Redis as a public token bucket? We optimized for LuaJIT in Apache APISIX. But it will not effective in Redis.
