Recover from Recycle Bin

To avoid disasters caused by accidental operations, Doris supports the recovery of accidentally deleted databases, tables, and partitions. After deleting a table or database, Doris does not immediately physically delete the data. When the user executes the DROP DATABASE/TABLE/PARTITION command without using FORCE, Doris moves the deleted database, table, or partition to the recycle bin. The RECOVER command can be used to restore all data of the deleted database, table, or partition from the recycle bin, making it visible again.

Note: If the deletion was performed using DROP FORCE, the data will be immediately deleted and cannot be recovered.

Query Recycle Bin

You can query the Recycle Bin with the following command:

SHOW CATALOG RECYCLE BIN [WHERE NAME [= "name" | LIKE "name_matcher"]];

For more detailed syntax and best practices, please refer to the SHOW-CATALOG-RECYCLE-BIN command manual, You can also type help SHOW CATALOG RECYCLE BIN on the MySql client command line for more help.
