<td>HashAgg is a widely used aggregation operator in TiDB for efficiently aggregating rows with the same field values. TiDB v8.0.0 introduces parallel HashAgg as an experimental feature to further enhance processing speed. When memory resources are insufficient, parallel HashAgg spills temporary sorted data to disk, avoiding potential OOM risks caused by excessive memory usage. This improves query performance while maintaining node stability. In v8.2.0, this feature becomes generally available (GA) and is enabled by default, enabling you to safely configure the concurrency of parallel HashAgg using <code>tidb_executor_concurrency</code>.</td>

<td>For clusters with a large number of tables and partitions, such as SaaS or PaaS services, improvement in statistics loading efficiency can solve the problem of slow startup of TiDB instances, and increase the success rate of dynamic loading of statistics. This improvement reduces performance rollbacks caused by statistics loading failures and improves cluster stability.</td>
