A new engineer discovers how Cloudflare used #LMDB for their distributed config https://xcancel.com/UltraSive/status/1948967694004326605#m
"99th %ile of reads dropped by two orders of magnitude!"
"LMDB stability has been exceptional. It has been running in production for over three years. We have experienced only a single bug and zero data corruption. Considering we serve over 2.5 trillion read requests and 30 million write requests a day on over 90,000 database instances across thousands of servers, this is very impressive."
