Apache Cassandra: 8 years in production
summary
A team replaced vendor modules to build their own remote banking system and adopted Apache Cassandra for its configurable consistency and fast writes. The talk covers three concrete stories: why Cassandra was chosen (configurable consistency, fast writes); using Cassandra to store user transactions with details about WITH TIMESTAMP and tombstone risks; and handling peak payroll-day load, including disk offloading and reducing iowait.
