SAVE_POINT

Function

Manages savepoints of Hudi tables.

Syntax

  • Creating a savepoint:

    call create_savepoint('[table_name]', '[commit_Time]', '[user]', '[comments]');

  • Viewing all existing savepoints

    call show_savepoints(table =>'[table_name]');

  • Rolling back a savepoint:

    call rollback_savepoint('[table_name]', '[commit_Time]');

Parameter Description

Parameter

Example

call create_savepoint('hudi_test1', '20220908155421949');
call show_savepoint(table =>'hudi_test1');
call rollback_savepoint('hudi_test1', '20220908155421949');

Precautions

  • MOR tables do not support savepoints.
  • The commit-related files before the latest savepoint are not cleaned.
  • If there are multiple savepoints, perform the rollback from the latest savepoint. The logic is as follows: roll back the latest savepoint; delete the savepoint; and roll back the next savepoint.

System Response

You can view query results on the client.
