Scale Beyond MySQL or PostgreSQL Without a Full Migration

This post details the use of SingleStore Flow with Change Data Capture (CDC) to incrementally migrate analytical workloads from MySQL and PostgreSQL to SingleStore Helios. It describes a gradual migration strategy where data is replicated from the source database to SingleStore while the application continues to write to the source. This allows teams to move specific data-intensive features, such as real-time reporting, search, and aggregations, to SingleStore without a full application cutover. Performance metrics for large-scale data migration (600GB in 3 hours, 1.5TB in under 2 hours, 75TB in a week) are provided. The post highlights the benefit of avoiding the operational overhead of building and managing custom replication platforms by using the integrated SingleStore Flow service.
