Context aware MySQL pools via HAProxy
At GitHub they use MySQL as their main datastore. The setup is a typical “single-writer-multiple-readers” design. They loadbalance between server pools using HAProxy, with some cleverness built in: Instead [of checking whether a MySQL server is live with mysql-check], we make our HAProxy pools context aware. We let the backend MySQL hosts make an informed …

When …
