Wondering if anyone can shed some light on the methodology for establishing connections with the PHP driver.
We have a few servers and for some reason they all seem open new connections at the same time. It will drop to around 5k connections, rise to 10k-12k and then slowly drop, until it is time to spike again.
Problem is these connections and associated queries are causing major latency for actual requests. And also when it is connecting, there is a query for some metadata that is large, which is requested for each connection?
