Huawei’s DRS (Data Replication Service) uses a specialized DBAdapter that calls reserved driver interfaces to apply change data capture (CDC) logs at wire speed. If you see logs like:
INFO: Using dbadapter reserved interface for direct path apply.
This indicates the driver is in “turbo mode,” bypassing conventional commit protocols.
The term "reserved interface" signals a departure from standard open-source drivers. A reserved interface is a set of methods, parameters, or connection properties that are intentionally not documented in public manuals. They are "reserved" for:

The reserved interface acts as a backdoor—a controlled, secure bypass that allows Huawei’s own management tools to achieve 3-5x higher throughput than generic drivers.
DBAdapter reserved interfaces in Huawei drivers are vendor-specific hooks that enable proprietary features, diagnostics, and firmware interactions. They offer powerful capabilities but carry risks: instability across updates, security exposure, and limited support. Prefer standard APIs, encapsulate vendor-specific logic, and use runtime detection and fallbacks when interacting with these interfaces. dbadapter reserved interface huawei driver
