Contains information about tables that drop table has been executed but data cleanup has not been actually performed.
Columns:
- `index` ([UInt32](../../sql-reference/data-types/int-uint.md)) — Index in marked_dropped_tables queue.
- `database` ([String](../../sql-reference/data-types/string.md)) — Database.
- `table` ([String](../../sql-reference/data-types/string.md)) — Table name.
- `uuid` ([UUID](../../sql-reference/data-types/uuid.md)) — Table uuid.
- `engine` ([String](../../sql-reference/data-types/string.md)) — Table engine name.

- `metadata_dropped_path` ([String](../../sql-reference/data-types/string.md)) — Path of table's metadata file in metadata_dropped directory.
- `table_dropped_time` ([DateTime](../../sql-reference/data-types/datetime.md)) — The time when the next attempt to remove table's data is scheduled on. Usually it's the table when the table was dropped plus `database_atomic_delay_before_drop_table_sec`
