### Description
my apisix's etcd cluster have to many watch request(6000 connections per
second),so i want to reduce the pressure of etcd cluster.if i can modify the
**config_etcd.lua**'s timer of new function timer from 0 to 0.5 or 1 like
this?(i have a test,and it can reduce the number of watch useful ,but i don't
know if this can due to a unexpected error)or if have better method to reduce
watch?
```
function _M.new(key, opts)
...
if automatic then
if not key then
return nil, "missing `key` argument"
end
if loaded_configuration[key] then
local res = loaded_configuration[key]
loaded_configuration[key] = nil -- tried to load
log.notice("use loaded configuration ", key)
local dir_res, headers = res.body, res.headers
load_full_data(obj, dir_res, headers)
end
ngx_timer_at(1, _automatic_fetch, obj)
else
local etcd_cli, err = get_etcd()
if not etcd_cli then
return nil, "failed to start a etcd instance: " .. err
end
obj.etcd_cli = etcd_cli
end
if key then
created_obj[key] = obj
end
return obj
end
