Descrizione

  1. Currently if we use the default code path for server segment download we won't retry download on untar failure. In situations as downloading partial tar file, this would not be helpful. There are two solutions:

    • improve the default code path in BaseTableDataManager
    • use the new stream download untar code path pinot.server.instance.segment.stream.download.untar
  2. The new stream download untar code path currently doesn't support stream decryption, as should be theoretically possible with block cipher. This potential improvement to stream segment download can be explored.
