Core Concept

Production Database

Database for production data

Shadow Database

The Database for stress test data isolation. Configurations should be the same as the Production Database.

Shadow Algorithm

Shadow Algorithm, which is closely related to business operations, currently has 2 types.

• Column based shadow algorithm Routing to shadow database by recognizing data from SQL. Suitable for stress test scenario that has an emphasis on data list.
• Hint based shadow algorithm Routing to shadow database by recognizing comments from SQL. Suitable for stress test driven by the identification of upstream system passage.
