      ARCHIVE volumes have a special format which is called SDFS. SDFS stands for "Storage Distributed File System". ARCHIVE volumes have a build in compression mechanism, incoming data will be compressed automatically while outgoing data will be decompressed automatically. The used compression algorithm is LZ4 (https://en.wikipedia.org/wiki/LZ4_(compression_algorithm)).

      • SDFS volumes will be formatted during creation
      • SDFS supports different Block Sizes
        • max. 16 TB for 64 KiB default
        • max. 24 TB for 96 KiB
        • max. 32 TB for 128 KiB
        • max. 64 TB for 256 KiB
        • max. 128 TB for 512 KiB
        • and so on
      • SDFS volumes can be connected using any HTTP(s) and (s)FTP(s) client, refer to SOL-351 and SOL-68
      • SDFS volumes can be used as remote ARCHIVE for another EXASOL cluster, refer to SOL-237
