Hi, I'm still pretty new to go. Hope this question isn't too stupid.
I'm writing a restful API server, and in order to send a response, I need to query a db to get its content type and then send the actually file that lives on the file system. Now the question is, should I put db.QueryRow and os.Open each in a goroutine to make them concurrent? And a more general question is, when using APIs from the stdlib or 3rd-party packages, how do I determine whether to wrap them in goroutines when more than one of them need to happen sequentially and the order actually doesn't matter? Should I manually time the API executions to make the call? Should I writing things sequentially by default and only when hitting performance problems do I profile the program and wrap calls in goroutine? How do you decide when to use goroutines? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
