В моем приложении nodejs я общаюсь с mySQL в экземпляре AWS RDS с помощью mysql -connection-pool-manager.
В случайные моменты (это может быть после несколько часов или несколько дней), запросы, следуя шаблону, описанному ниже, начинают составлять как MySQL процессы со статусом «отправка данных» до тех пор, пока не будет доступно соединение, и ЦП сервера БД не достигнет своего максимума.
let sql = `SELECT * FROM jobs WHERE hash = "${hash}" AND (expiryDate = -1 OR expiryDate > "${moment().format('YYYY-MM-DD HH:mm:ss')}") ORDER BY createdDate DESC LIMIT ${limit};`
В обычное время выполнение запросов занимает менее 100 мс. Никакой другой запрос в моем коде не вызывает такого поведения.
Вот что дает EXPLAIN:
id select_type table partitions type possible_keys key key_len ref rows filtered Extra
-------------------------------------------------------------------------------------------
1 SIMPLE jobs NULL ref hash,expiryDate hash 41 const 38 1.45 Using index condition; Using where; Using filesort
Вот моя NodeJS конфигурация:
import PoolManager from 'mysql-connection-pool-manager';
const mySQLSettings = {
connectionLimit : 30,
host : MYSQL_HOST,
user : MYSQL_USER,
password : MYSQL_PWD,
port : MYSQL_PORT,
database : MYSQL_DB,
debug : false
}
const options = {
idleCheckInterval: 1000,
maxConnextionTimeout: 30000,
idlePoolTimeout: 3000,
errorLimit: 5,
preInitDelay: 50,
sessionTimeout: 60000,
stringifyObjects: true,
mySQLSettings
}
const dbPool = PoolManager(options)
const sql = `SELECT * FROM jobs WHERE hash = "${hash}" AND (expiryDate = -1 OR expiryDate > "${moment().format('YYYY-MM-DD HH:mm:ss')}") ORDER BY createdDate DESC LIMIT ${limit}`
const res = new Promise( ( resolve, reject ) => {
dbPool.query(sql, (results, error) => {
if (error) reject(error);
resolve(results)
});
})
My AWS Сервер:
- vCPU: 1
- ОЗУ: 2 ГБ
- Тип хранилища: Универсальный (SSD)
