There are o lot of SQL Load Balancer in IT World. Just like below
Actually Danel decided to reach another main goals.
- to balance OLAP / OLTP SQL traffic between PostgreSQL databases
- to gather statistics about usage of underlying databases to make a more effective balance
- to balance between database nodes based on current database loading
- to balance with support to store query in queue
Sounds really good and awesome, especially split OLAP / OLTP SQL traffic!
