+Doris supports automatic or manual statistics collection for tables from
external data sources like Hive、Iceberg and Paimon. The accuracy of statistics
directly determines the accuracy of cost estimation, which is crucial for
selecting the optimal query plan. This can significantly improve query
execution efficiency, especially in complex query scenarios.
+For details, please refer to the
[Statistics](../query-acceleration/optimization-technology-principle/statistics#外表收集)
document in the "External Table Collection" section.
