AppsFlyer: Large Scale NoSQL DB Migration Under Fire

Appsflyer, a mobile attribution ad tech company, switched to Aerospike to replace an unstable Couchbase database that struggled with performance and reliability issues. Their previous database, composed of nearly 50 instances on AWS, faced constant failures, with backups taking more than a day and inadequate support. After migrating two billion records to a smaller, more stable Aerospike cluster, they saw immediate improvements in stability and cost savings, reducing hardware costs by two-thirds. Aerospike’s reliability allowed Appsflyer to enhance features and focus on critical tasks without database concerns.
