After 1.4.1, Nacos provide a method to configure the HikariCP connection pool. db.pool.config is the configuration prefix, xxx is the actual hikariCP configuration, such as db.pool.config.connectionTimeout or db.pool.config.maximumPoolSize and so on. For more configuration of hikariCP, please check HikariCP It should be noted that url, user, password will be rewrite by db.url.n, db.user, db.password, and driverClassName is the default MySQL8 driver which supports mysql5.x.
