如何从 tarantool 连接到 mysql?
How to connect from tarantool to mysql?
我尝试使用 tarantool 作为应用程序服务器,并希望从 tarantool 连接到 mysql。
在lua中我写了一个函数:
local function mysql_data(query, limit)
local conn = mysql.connect({host = mysql_host, user = mysql_user, password = mysql_password, db = mysql_database})
local tuples = conn:execute(query, limit)
return tuples
end
但在日志中我看到:
