您可以使用db事务。db事务不会导致超时（但如果您滥用它们，它们可能会导致死锁）
例如，您可以使用以下承诺：；

execInTransaction: function (pool) {
        return new Promise((resolve, reject) => {
            pool.getConnection(function (err, connection) {
                logger.debug("Connection opened " + connection.threadId);
                if (err) return reject(err);
                connection.beginTransaction(function (err1) {
                    if (err1) return reject(err1);

                    // Loop and insert 200 items at each time.. 

                    connection.commit(commitError => {
                        connection.release();
                        if (commitError != null) {
                            return reject(commitError);
                        }
                        return resolve("<some result>");
                    });
                }).catch(txnError => {
                    connection.rollback((rollbackError) => {
                        connection.release();
                        if (rollbackError != null) {
                            logger.error("Connection rollback failed. " + connection);
                            return reject(rollbackError);
                        } else {
                            return reject(txnError);
                        }
                    });
                });
            });
        });
    },
