I have a 3 node cluster setup with haproxy/apache/nginx/php/galeramariadb.
I am searching a way to minimise my tcp/ip timeout between cluster failover. Currently my domain hosted on this 3node cluster has an A record with 3 ip addresses.
If i loose a node, few seconds required for detecting this timeout and for the browser to pickup another ip address
i am searching how to minimise this few seconds downtime between failover. route53 is my dns provider.
