Hi Alexandre,
Thank you for the explanation. I understand that reasoning very well now. Jon, appreciate the link, and will follow up there for this sort of thing then. Thanks, Kevin From: Alexandre Dutra <alexandre.du...@datastax.com> Reply-To: "user@cassandra.apache.org" <user@cassandra.apache.org> Date: Wednesday, December 11, 2019 at 3:33 AM To: "user@cassandra.apache.org" <user@cassandra.apache.org> Subject: [EXTERNAL] Re: Connection Pooling in v4.x Java Driver *EXTERNAL SENDER* 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.

Is anyone aware of the reasoning for this departure from dynamic pool sizing, which I believe was available in v3.x?
