DeltaGlider reduces storage costs by storing only binary deltas between similar files. Achieves 99.9% compression for versioned artifacts. Key features: - Intelligent file type detection (delta for archives, direct for others) - Drop-in S3 replacement with automatic compression - SHA256 integrity verification on every operation - Clean hexagonal architecture - Full test coverage - Production tested with 200K+ files Case study: ReadOnlyREST reduced 4TB to 5GB (99.9% compression)
