Learn how their database infrastructure evolved from a PostgreSQL database, but began to show limitations and was a single point of failure. Growing through a few intermediary steps, including Amazon DynamoDB, eventually, turning to Scylla for its data model and collections to condense multiple tables. Using Scylla, iFood reduced the time to process events and acknowledgments (from ~80ms to ~3ms) and reduced costs using Scylla vs DynamoDB by over 9x.
