Hi, In driver 4.x, pools do not resize dynamically anymore because the ratio between concrete benefits brought by this feature and the maintenance burden it caused was largely unfavorable: most bugs related to connection pooling in driver 3.x were caused by the dynamic pool resizing. Having a fixed pool size made driver 4.x pool implementation much more straightforward and robust.
