  // 'max' limits the total number of concurrent connections this pool will keep. Ideal
  // values for this setting are highly variable on app design, infrastructure, and database.
  (config.pool.max = 5);
// 'min' is the minimum number of idle connections maintained in the pool.
// Additional connections will be established to meet this value unless the pool is full.
