Haymarket Media Group, a leading privately owned media company, has migrated its classified advertising product catalog from MySQL to MongoDB, achieving 8x higher platform efficiency. The move was driven by scalability challenges with MySQL and the need for a more sophisticated database system that could handle increased traffic and provide personalized user experiences. By leveraging MongoDB's dynamic schema and JSON document model, Haymarket was able to reduce infrastructure costs, simplify its web tier, and boost performance and reliability. Additionally, MongoDB has enabled the company to quickly develop new features and reports, making it an integral part of their replatforming efforts in the cloud.
