########## docs/en/docs/query-acceleration/statistics.md: ########## @@ -75,7 +75,7 @@ This feature collects statistics only for tables and columns that either have no For tables with a large amount of data (default is 5GiB), Doris will automatically use sampling to collect statistics, reducing the impact on the system and completing the collection job as quickly as possible. Users can adjust this behavior by setting the `huge_table_lower_bound_size_in_bytes` FE parameter. If you want to collect statistics for all tables in full, you can set the `enable_auto_sample` FE parameter to false. For tables with data size greater than `huge_table_lower_bound_size_in_bytes`, Doris ensures that the collection interval is not less than 12 hours (this time can be controlled using the `huge_table_auto_analyze_interval_in_millis` FE parameter). -The default sample size for automatic sampling is 200,000 rows, but the actual sample size may be larger due to implementation reasons. If you want to sample more rows to obtain more accurate data distribution information, you can configure the `auto_analyze_job_record_count` FE parameter. +The default sample size for automatic sampling is 4194304 rows, but the actual sample size may be larger due to implementation reasons.
