Percona and HandlerSocket
This is huge news. In case you aren’t aware, HandlerSocket is a raw protocol interface that is similar to a dictionary lookup (kind of like memcached, or a hashtable) and does NOT go through the SQL parser.
The performance implications are huge as this thing flies.
Most web applications access data in terms of key/values. In fact, databases like Redis take the concept a bit further and implement functions you can use to manipulate keys directly.
What’s interesting here is that I think HandlerSocket is bigger than Percona and probably deserves a whole project and open source community behind it directly.
