Three bugs in the Go MySQL Driver
> Adding to this challenge, authzd is deployed to our Kubernetes clusters, where we’ve been experiencing issues with high latencies when opening new TCP connections, something that particularly affects the pooling of connections in the Go MySQL driver. One of the most dangerous lies that programmers tell themselves is that the network is reliable, because, well, most of the time the network is reliable. But when it gets slow or spotty, that’s when things start breaking, and we get to find out the underlying issues in the libraries we take for granted.
Good walkthrough of dealing with some unfriendly bugs.
