### Purpose In high-concurrency point query scenarios on the primary key table, we observed high CPU usage mainly caused by deserialization overhead of DV metadata. Currently, reading deletion vector metadata for a single bucket requires reading and deserializing a large number of entries from the index manifest, if the table has many partition and buckets. <img width="2553" height="955" alt="image" src="https://github.com/user-attachments/assets/b557a11e-57f3-4c6b-a3dc-f5bc2b798978"; /> This PR introduces a bucket-level dv meta cache which reduces CPU load and significantly improves QPS for single-bucket query scenarios on primary key tables. ### Tests ### API and Format ### Documentation -- This is an automated message from the Apache Git Service.
