| * **Online/Offline Node Optimization:** Refactored the ISR (In-Sync Replica) update mechanism and replica synchronization logic and enhanced idempotency guarantees. This significantly improves system stability and reduces the risk of data loss during node failures. | ||
| * **Server Metadata Caching:** Introduced a consistent metadata caching layer on the server side. Clients now fetch metadata from the local server cache instead of ZooKeeper, significantly reducing request latency and pressure on ZooKeeper. | ||
| * **Server Rack-Aware Support:** During replica assignment, the system automatically avoids placing multiple replicas within the same "rack", thereby significantly improving fault tolerance and high availability. This feature is especially beneficial in multi-AZ deployments and large-scale data center disaster recovery scenarios. | ||
| * **Accelerated Table Creation:** Leveraged batched metadata updates to reduce table initialization time. For example, the time for a table creation with 1024 buckets was reduced from **minutes** to **milliseconds**. |

Specific numbers would be more credible. How time have we reduced? Not a mandate, just a suggestion.
