# How To Quickly Recover Data
+ DML method
  + tidb_snapshot parameter
+ DDL method
  + flashback table
  + recover table
+ DML DDL method
  + dumpling tool

------------------------------------------------------------
- DML operations
  Read historical data through the system variable tidb_snapshot.
  It is suitable for repairing cases where the amount of data is low.

- DDL operations
  Both Flashback Table and Recover Table perform data recovery after retrieving the metadata of the table by read the snapshot. It's just a different scope of application.

- DML+DDL operations
 Dumpling can export data based on a point in time with the —snapshot parameter.
  This applies to situations where DML changes a lot of data, and also applies to DDL operations.
