Connection pool not creating

[first-mine]

`local red = redis:new()
red:set_timeout(10000)
local options_table = {}
options_table.pool_size = 1
options_table.backlog = 1

local ok, err = red:connect(redis_endpoint, redis_port, options_table)
ngx.say("reused times: ", red:get_reused_times())`

How to make sure that connection pool is created ???
For testing purpose kept the pool_size as 1, so that the same connection get reused.
But every time the red:get_reused_times() returns 0, that means new connection getting created everytime, instead of using the existing pool.

Is their any issue with the code ?

you need to put the connection to the connection pool via set_keepalive.
go to https://github.com/openresty/lua-resty-redis#set_keepalive for deatail

@zhuizhuhaomeng I have tried that, using set_keepalive returning closed for every subsequent request.

The issue I am trying to solve here is, ERR max number of clients reached
This error is coming due to large number of redis connection in my application.
So, I thought creating a connection pool with backlog, would queue up those extra requests to process later instead of throwing that error.
