GBASE Helps Bank of Yantai Migrate to Independently Developed Databases

As a vital component of Bank of Yantai’s core banking operations, the Tag Management Platform handles big‑data analytics and tag‑management capabilities for customers, supporting key business functions such as targeted marketing, customer profiling, and risk management. The system originally ran on an overseas‑sourced distributed database, which provided stable support in the early stages. However, as business expanded and data volumes surged, the overseas‑sourced database gradually revealed limitations in performance, scalability, security and compliance. To address these challenges, Bank of Yantai decided to replace the existing database with GBase distributed database, an independently‑developed offering.

This project deployed a three‑node GBase distributed database cluster on three virtual machines, each configured with 16‑core CPUs, 64 GB memory, and 523 GB storage. The DMT tool enabled one‑click full‑data migration and real‑time incremental synchronization, while intelligent SQL translation guaranteed statement‑level compatibility. A shadow‑playback mechanism was leveraged for performance stress testing and validation, and a gray‑scale traffic routing strategy delivered zero‑code cut‑over to ensure seamless transition. Ultimately, the deployment met the high‑availability standard with an RTO of less than five minutes, supporting the efficient and stable go‑live of the Tag Management Platform within the IT‑compliant environment.

The successful delivery of this independently‑developed database replacement project has significantly boosted security, performance‑optimization capabilities and compliance levels for Bank of Yantai’s core systems, while enhancing their horizontal scalability. This technical upgrade not only provides agile and reliable underlying support for banking business innovation, but also improves customer service quality through increased data‑processing efficiency, thereby strengthening the bank’s market competitiveness amid digital‑era competition and injecting new momentum into its sustainable development.
