Abstract Value Members

  1. abstract def vacuum(): Unit

    Recursively delete files and directories in the table that are not needed by the table for maintaining older versions up to the given retention threshold.

    Recursively delete files and directories in the table that are not needed by the table for maintaining older versions up to the given retention threshold. This method will return an empty DataFrame on successful completion.

    note: This will use the default retention period of 7 days.

  2. abstract def vacuum(retentionHours: Double): Unit

    Recursively delete files and directories in the table that are not needed by the table for maintaining older versions up to the given retention threshold.

    Recursively delete files and directories in the table that are not needed by the table for maintaining older versions up to the given retention threshold. This method will return an empty DataFrame on successful completion.

    retentionHours

    The retention threshold in hours. Files required by the table for reading versions earlier than this will be preserved and the rest of them will be deleted.
