Hi ,

I want to establish connection to say redis once and then subsequently use this handle for get /set requests.
How can I achieve this ?
Should I open connection in init_worker_by_lua and then use it at my location ?

Is the following syntax right ?

init_worker_by_lua '
redis = require "resty.redis"
red = redis:new()
red:set_timeout(100)
local ok, err = red:connect("127.0.0.1", 6379)
...
...
';

location /redis {
content_by_lua '
local res, err = red:get("xyz")
...
...
';

thank you for your time ..

Hello,

I think you should open a new connection for each new request:

local red =require ("resty.redis"):new()

red:set_timeout(100)
local ok, err = red:connect("127.0.0.1", 6379)

......

and at the end of the processing you should use

ok, err = red:set_keepalive(max_idle_timeout, pool_size) in order to keep the connection in the connection pool.
