How to access MySQL from multiple threads concurrently

Question

We\'re doing a small benchmark of MySQL where we want to see how it performs for our data.

Part of that test is to see how it works when multiple concurrent threads

Answer 1

Seems clear to me from the mySQL Docs that any specific MYSQL structure can be used in a thread without difficulty - using the same MYSQL structure in different threads simultaneously is clearly going to give you extremely unpredictable results as state is stored within the MYSQL connection.

Thus either create a connection per thread or used a pool of connections as suggested above and protect access to that pool (i.e. reserving or releasing a connection) using some kind of Mutex.
