also I'm not sure about whether to many connections
is normal in this situation.

@Pronan It is your responsibility to limit backend concurrency level by means of libraries like lua-resty-limit-traffic
.

Sorry, I've checked the document but I don't quite get it and don't know how to use it in my create.lua
. Let me provide more info.
The whole process is simple: I insert the huge itmes via making a single request /create
in browser and then trigger a lua loop in nginx. During the loop, I think there should be only one connection to mysql server. So I don't know why the error too many connections
occurred.
Am I wrong? Or is it related to the Non-blocking design of openresty?
nginx.conf
location = /create {
content_by_lua_file create.lua;
}
create.lua
local query = require "query"
for i, e in ipairs(huge_array) do
local res, err = query(string.format('insert into sbk (c1, c2) values (%s, %s);', e[1],e[2]))
end
If not ok, I could provide the server environment.
