Which of the following statements about PolarDB's endpoints is NOT correct?

The primary endpoint of PolarDB is designed to manage all database operations, and it plays a central role in handling read and write requests. While it does provide a single entry point for operations, the primary endpoint is primarily responsible for handling write requests and can also support read requests when the read/write splitting capability is configured correctly.

This means that while it may handle reads under certain configurations, it is not accurate to state that the primary endpoint supports read/write splitting as a regular feature, which is generally more associated with read replicas and additional endpoints designed specifically for load distribution. Thus, stating that the primary endpoint supports read/write splitting is misleading, making this choice not correct.

The design of PolarDB allows various endpoints to manage interactions with data effectively, but the primary endpoint itself centers more on write operations. Other endpoints are more suitable for segregating read operations, reflecting a more accurate architecture of how these systems typically operate.
