How Allegro Group Saves Latency and Money With ScyllaDB

Allegro Group, a leading e-commerce company in Poland, faced challenges with their existing 44-node Apache Cassandra cluster, which struggled with latency and performance issues that risked breaching their 100-millisecond service level agreement (SLA). To address these concerns, Allegro's database team, led by Lukasz Pachiarek and Szymon Szymanski, evaluated ScyllaDB as a potential solution. They found that ScyllaDB significantly outperformed Apache Cassandra in terms of maintenance tasks like cleanup, node joining, and decommissioning, as well as in production traffic scenarios. ScyllaDB's performance improvements eliminated latency spikes, allowing Allegro to maintain better response times while reducing hardware requirements, ultimately replacing their 44-node Cassandra cluster with a more efficient 16-node ScyllaDB setup. This transition not only enhanced their system's efficiency but also aligned with Allegro's need for faster response times to meet customer expectations and protect sales.
