Research direction
Read src/query/storages/system/src/statistics_table.rs, especially the registered columns and statistics fields, then compare the structure and conventions of the system.columns and system.tables pages. Create docs/en/sql-reference/00-sql-reference/31-system-tables/system-statistics.md describing the table and its available data; done means the missing system.statistics page matches the surrounding documentation.

Description
Missing Documentation: system.statistics
The system.statistics system table is implemented in the Databend source code but has no corresponding documentation page.
Source Code
- File:
src/query/storages/system/src/statistics_table.rs - Registered name:
statistics(line 103)
What it does
The system.statistics table provides column-level statistics for all tables across all catalogs and databases. It exposes fields including column_name, database_name, table_name, and associated statistics data. It iterates over all catalogs, databases, and tables (including virtual columns) to collect per-column statistics.
