A connection pool size of 37 is a scar. Someone ran out of connections on a Tuesday afternoon, tried 50, watched latency spike, backed off to 40, still too high, landed on 37 after a week of graphs, and committed it with &ldquo;tune pool size.&rdquo; The code says what happens. The config says what happened.</p> <p>Nobody talks about config though. Not the twelve-factor app kind, not the &ldquo;should we use YAML or TOML&rdquo; kind. The actual values. The numbers someone picked and committed without a PR description, three years ago, that are still running in production.</p>
