Josh is a Database Engineer at Fitbit. A veteran infrastructurer, he has been known to work on everything from load-balancers to deployment to metrics collection. His biggest focus is stateful services, including datastores of both the SQL (MySQL, Postgres) and NoSQL (Cassandra, Consul) variety. Recently he’s been spending a lot of time with Cassandra: scaling, monitoring, and automating Fitbit’s clusters. Strike up a conversation with him about methods for securing Postgres authentication, restoring backups extremely quickly, or providing a consistent view of a replicated MySQL cluster.
