siaron opened a new issue #5223:
URL: https://github.com/apache/apisix/issues/5223
### Issue description
```
local red = redis_new()
local timeout = conf.redis_timeout or 1000 -- 1sec
core.log.info("ttl key: ", key, " timeout: ", timeout)
red:set_timeouts(timeout, timeout, timeout)
local ok, err = red:connect(conf.redis_host, conf.redis_port or 6379)
if not ok then
return false, err
end
local count
count, err = red:get_reused_times()
if 0 == count then
if conf.redis_password and conf.redis_password ~= '' then
local ok, err = red:auth(conf.redis_password)
if not ok then
return nil, err
end
end
-- select db
if conf.redis_database ~= 0 then
local ok, err = red:select(conf.redis_database)
if not ok then
return false, "failed to change redis db, err: " .. err
end
end
elseif err then
-- core.log.info(" err: ", err)
return nil, err
end
```
每次都会重新创建一个redis 的connection吗? 还是
```
local ok, err = red:connect(conf.redis_host, conf.redis_port or 6379)
```
这一步后面后连接池?
