Blazing Fast Petabyte Scale Static Web Server + Tools.

Serve Billion Files from an Indexed, Compressed and Deduplicated Archive.

Think of tar + gzip + dedup + web-server - alike combination on steroids

• Pack lots of files in directory/sub-directories into several files (data file + indexes)
• Deduplicate File Contents
• Optionally Compress Files, better compression level than tar.gz
• Fast Web Server
  • 20K/sec random queries, 200MByte/sec effective network traffic (10Gbe network, developer PC, 400GB archive)
  • Low Memory Usage:
    • 2-level-index needs only ~3MB RAM for 100M files, ~20MB for billion archived files
• Compact and Efficient Indexes
• Limits:
  • Max Archive(Shard) Size: 256TB (2**48)
  • Max Shards: 65536 (2**16)
  • Max Stored Data Size: 16,777PB (petabytes) || 16.7EB (exabytes)
  • Max Archived File Size: 1TB (2**40)
  • Max Archived File Count: 4.3 Billion files (2**32)
  • File-Content-Hash: 80bit
  • File-Name-Hash: 80bit
• Recommendations:
  • use SSD (hard disks can't handle random access)
• MIT licensed Open Source Project
• Can use filesystem or raw-partition for data storage

• Export whole/part-of web site as static pages, serve it
• Use as a static pages server for your project, deploy/rollback your files in a second
• backup solution with deduplication - keep history, cheap snapshots for your project
• Combine OpenStreetMap map-tiles in one file, avoid filesystem overhead, serve them super fast
• use nginx as front-end http2 server

• high performance bigpack server written in golang
• 20K/sec random requests on 400GB archive
• 200MB/sec http traffic served on developer's computer (10Gbe network)
