Savepoint

Savepoints are used to save and restore custom version data.

Savepoints provided by Hudi can save different commits so that the cleaner program does not delete them. You can use rollback to restore them later.

Use spark-sql to manage savepoints.

Example:

  • Creating a savepoint
    call create_savepoints('hudi_test1', '20220908155421949');
  • Viewing all existing savepoints
    call show_savepoints(table =>'hudi_test1');
  • Rolling back a savepoint
    call rollback_savepoints('hudi_test1', '20220908155421949');

MOR tables do not support savepoints.
