Thread Safety

Transactor is stateless and thread-safe. Share a single instance across your application.

Each call to transactor.execute(...) obtains its own connection from the underlying ConnectionSource. Connections are not shared across operations or threads.

Do not share connections across threads. If you need to run multiple operations on the same connection (e.g., within a transaction), do so within a single transact block:

tx.transact(mc -> {
    var user = mc.execute(findUser);
    var orders = mc.execute(findOrders);
    return new Dashboard(user, orders);
});
