A TCP router written on Golang.
Developed to replace HAProxy as the proxy tier enabling high availability for the MySQL dbaas for Cloud Foundry. Responsible for routing of client connections to a one node at a time of a backend cluster, and failover on cluster node failure. For more information, see the develop branch of cf-mysql-release/docs/proxy.md.
There are several other proxies out there: Nginx, HAProxy and even MariaDB's MaxScale. None of them met a specific criteria which is critical for the performance of the cluster in the case that a database server becomes unhealthy but is still accessible. Switchboard detects this condition (via healthchecks) and severs the connection. This forces the client to reconnect, and will be routed to a healthy backend. From the client's perspective it looks like it is connected to a single backend that briefly disappeared and is immediately available again.
