Henan Unicom Historical Database Project

Henan Unicom’s historical database stores long-term online historical data such as user itemized bills and invoices, enabling quick queries of historical call records and bills in the repository. As user numbers and business volumes continue to grow, Henan Unicom requires: the database used as the historical repository must provide a high compression ratio to store massive amounts of historical data; the system must have continuous scalability and support online expansion to minimize impact on user experience.

Automatic Compression: Automatically selects compression algorithms based on data type, turning long-term offline data into immediately usable online data.

High Performance: Achieves loading speeds up to 2 TB/hour, rapidly ingesting historical data into the database.

Storage Savings: Dramatically reduces reliance on high-end storage, driving significant cost efficiencies.

Offline-to-Online: Transforms data traditionally confined to tape into online assets, enabling seamless future use.
