The document summarizes Cocolog's migration from PostgreSQL to MySQL. Cocolog is a blogging platform operated by NIFTY Corporation, one of Japan's largest internet service providers. It experienced rapid growth and faced scaling issues with PostgreSQL. The migration involved carefully partitioning user data across multiple MySQL servers for improved performance and high availability. Key steps included writing user metadata to a global MySQL database, migrating each user's data asynchronously, and configuring new users to specific user partitions.
