The PlanetScale team successfully migrated their Query Insights database from a traditional MySQL setup to Metal, a high-performance, scalable database service. The migration involved upgrading one of the eight shards of the database to Metal, which resulted in significant performance improvements, with query latency decreasing substantially across all measured percentiles. The upgrade was achieved without changes to the application architecture or sharding configuration, and has provided substantial benefits including lower average backlog in Kafka consumers and additional capacity for handling increasing message volume.
