Data Recover

Data Deletion Recovery

In order to avoid disasters caused by misoperation, Doris supports data recovery of accidentally deleted databases/tables/partitions. After dropping table or database, Doris will not physically delete the data immediately, but will keep it in Trash for a period of time ( The default is 1 day, which can be configured through the catalog_trash_expire_second parameter in fe.conf). The administrator can use the RECOVER command to restore accidentally deleted data.
