Abstract
Illustrative embodiments provide an efficient, resilient high-availability ('HA') router architecture. In illustrative embodiments, metric and event data is made resilient to node failover by replication. The same data is stored on the database of each router. Instead of pushing metrics directly from all of each node's software to each node's database, replication is instead handled by the database loader application subscribing to queues on both nodes. In some embodiments, records are written in the queues to topics that have a certain time to live (TTL), so the loader on one node has the duration of the TTL to read from the other node's queue in order to achieve replication.
