Interface DeleteOrphanFiles

    • Method Detail

      • location

        DeleteOrphanFiles location​(java.lang.String location)
        Passes a location which should be scanned for orphan files.

        If not set, the root table location will be scanned potentially removing both orphan data and metadata files.

        Parameters:
        location - the location where to look for orphan files
        Returns:
        this for method chaining
      • olderThan

        DeleteOrphanFiles olderThan​(long olderThanTimestamp)
        Removes orphan files only if they are older than the given timestamp.

        This is a safety measure to avoid removing files that are being added to the table. For example, there may be a concurrent operation adding new files while this action searches for orphan files. New files may not be referenced by the metadata yet but they are not orphan.

        If not set, defaults to a timestamp 3 days ago.

        Parameters:
        olderThanTimestamp - a long timestamp, as returned by System.currentTimeMillis()
        Returns:
        this for method chaining
      • deleteWith

        DeleteOrphanFiles deleteWith​(java.util.function.Consumer<java.lang.String> deleteFunc)
        Passes an alternative delete implementation that will be used for orphan files.

        This method allows users to customize the delete func. For example, one may set a custom delete func and collect all orphan files into a set instead of physically removing them.

        If not set, defaults to using the table's io implementation.

        Parameters:
        deleteFunc - a function that will be called to delete files
        Returns:
        this for method chaining
