Queries the status and results of a storage analysis task.
Operation description
- This operation is applicable only to ApsaraDB RDS for MySQL instances and PolarDB for MySQL clusters.
- The physical file size indicates the actual size of an obtained file. Only specific deployment modes of database instances support the display of physical file sizes. The statistics on tables are obtained from information_schema.tables. Due to the asynchronicity of the statistics update mechanism in MySQL, statistics and analysis results may not be perfectly accurate. You can execute the ANALYZE TABLE statement on related tables during off-peak hours to obtain the latest information.
