Interface RewriteFiles

  • All Superinterfaces:
    PendingUpdate<Snapshot>, SnapshotUpdate<RewriteFiles>

    public interface RewriteFiles
    extends SnapshotUpdate<RewriteFiles>
    API for replacing files in a table.

    This API accumulates file additions and deletions, produces a new Snapshot of the changes, and commits that snapshot as the current.

    When committing, these changes will be applied to the latest table snapshot. Commit conflicts will be resolved by applying the changes to the new latest snapshot and reattempting the commit. If any of the deleted files are no longer in the latest snapshot when reattempting, the commit will throw a ValidationException.
