DeltaGlider

Store 4TB of similar files in 5GB. No, that's not a typo.

DeltaGlider is a drop-in S3 replacement that may achieve 99.9% size reduction for versioned compressed artifacts, backups, and release archives through intelligent binary delta compression (via xdelta3).

The Problem We Solved

You're storing hundreds of versions of your software releases. Each 100MB build differs by <1% from the previous version. You're paying to store 100GB of what's essentially 100MB of unique data.

Sound familiar?

Real-World Impact

From our ReadOnlyREST case study:

Before: 201,840 files, 3.96TB storage, $1,120/year
After: Same files, 4.9GB storage, $1.32/year
Compression: 99.9% (not a typo)
Integration time: 5 minutes

Quick Start

The quickest way to start is using the GUI

CLI Installation

# Via pip (Python 3.11+)
pip install deltaglider

# Via uv (faster)
uv pip install deltaglider

# Via Docker
docker run -v ~/.aws:/root/.aws deltaglider/deltaglider --help

Docker Usage

DeltaGlider provides a secure, production-ready Docker image with encryption always enabled:

# Basic usage with AWS credentials from environment
docker run -e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY \
  deltaglider/deltaglider ls s3://my-bucket/

# Mount AWS credentials
docker run -v ~/.aws:/root/.aws:ro \
  deltaglider/deltaglider cp file.zip s3://releases/

# Use memory cache for ephemeral CI/CD pipelines (faster)
docker run -e DG_CACHE_BACKEND=memory \
  -e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY \
  deltaglider/deltaglider sync ./dist/ s3://releases/v1.0.0/

# Configure memory cache size (default: 100MB)
docker run -e DG_CACHE_BACKEND=memory \
  -e DG_CACHE_MEMORY_SIZE_MB=500 \
  -e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY \
  deltaglider/deltaglider cp large-file.zip s3://releases/

# Use MinIO or custom S3 endpoint
docker run -e AWS_ENDPOINT_URL=http://minio:9000 \
  -e AWS_ACCESS_KEY_ID=minioadmin \
  -e AWS_SECRET_ACCESS_KEY=minioadmin \
  deltaglider/deltaglider ls s3://test-bucket/

# Persistent encryption key for cross-container cache sharing
# (Only needed if sharing cache across containers via volume mount)
docker run -v /shared-cache:/tmp/.deltaglider \
  -e DG_CACHE_ENCRYPTION_KEY=$(openssl rand -base64 32) \
  deltaglider/deltaglider cp file.zip s3://releases/

Environment Variables:

DG_LOG_LEVEL: Logging level (default: INFO, options: DEBUG, INFO, WARNING, ERROR)
DG_MAX_RATIO: Maximum delta/file ratio (default: 0.5, range: 0.0-1.0) - 📖 Complete Guide
DG_CACHE_BACKEND: Cache backend (default: filesystem, options: filesystem, memory)
DG_CACHE_MEMORY_SIZE_MB: Memory cache size in MB (default: 100)
DG_CACHE_ENCRYPTION_KEY: Optional base64-encoded encryption key for cross-process cache sharing
DG_DISABLE_EC2_DETECTION: Disable EC2 instance detection (default: false, set to true to disable)
AWS_ENDPOINT_URL: S3 endpoint URL (default: AWS S3)
AWS_ACCESS_KEY_ID: AWS access key
AWS_SECRET_ACCESS_KEY: AWS secret key
AWS_DEFAULT_REGION: AWS region (default: us-east-1)

💡 Tip: DG_MAX_RATIO is a powerful tuning parameter. See the DG_MAX_RATIO guide to learn how to optimize compression for your use case.

Security Notes:

Encryption is always enabled (cannot be disabled)
Each container gets ephemeral encryption keys for maximum security
Corrupted cache files are automatically deleted
Use DG_CACHE_ENCRYPTION_KEY only for persistent cache sharing (store securely)

Basic Usage

# Upload a file (automatic delta compression)
deltaglider cp my-app-v1.0.0.zip s3://releases/

# Download a file (automatic delta reconstruction)
deltaglider cp s3://releases/my-app-v1.0.0.zip ./downloaded.zip

# List objects
deltaglider ls s3://releases/

# Sync directories
deltaglider sync ./dist/ s3://releases/v1.0.0/

# Migrate existing S3 bucket to DeltaGlider-compressed storage
deltaglider migrate s3://old-bucket/ s3://new-bucket/

That's it! DeltaGlider automatically detects similar files and applies 99%+ compression. For more commands and options, see CLI Reference.

Core Concepts

How It Works

Traditional S3:
  v1.0.0.zip (100MB) → S3: 100MB
  v1.0.1.zip (100MB) → S3: 100MB (200MB total)
  v1.0.2.zip (100MB) → S3: 100MB (300MB total)

With DeltaGlider:
  v1.0.0.zip (100MB) → S3: 100MB reference + 0KB delta
  v1.0.1.zip (100MB) → S3: 98KB delta (100.1MB total)
  v1.0.2.zip (100MB) → S3: 97KB delta (100.3MB total)

DeltaGlider stores the first file as a reference and subsequent similar files as tiny deltas (differences). When you download, it reconstructs the original file perfectly using the reference + delta.

Intelligent File Type Detection

DeltaGlider automatically detects file types and applies the optimal strategy:

File Type	Strategy	Typical Compression	Why It Works
`.zip`, `.tar`, `.gz`	Binary delta	99%+ for similar versions	Archive structure remains consistent between versions
`.dmg`, `.deb`, `.rpm`	Binary delta	95%+ for similar versions	Package formats with predictable structure
`.jar`, `.war`, `.ear`	Binary delta	90%+ for similar builds	Java archives with mostly unchanged classes
`.exe`, `.dll`, `.so`	Direct upload	0% (no delta benefit)	Compiled code changes unpredictably
`.txt`, `.json`, `.xml`	Direct upload	0% (use gzip instead)	Text files benefit more from standard compression
`.sha1`, `.sha512`, `.md5`	Direct upload	0% (already minimal)	Hash files are unique by design

Key Features

AWS CLI Replacement: Same commands as aws s3 with automatic compression
boto3-Compatible SDK: Works with existing boto3 code with minimal changes
Zero Configuration: No databases, no manifest files, no complex setup
Data Integrity: SHA256 verification on every operation
S3 Compatible: Works with AWS S3, MinIO, Cloudflare R2, and any S3-compatible storage

Python SDK

📚 Full SDK Documentation | API Reference | Examples | boto3 Compatibility Guide

boto3-Compatible API (Recommended)

DeltaGlider provides a boto3-compatible API for core S3 operations (21 methods covering 80% of use cases):

from deltaglider import create_client

# Drop-in replacement for boto3.client('s3')
client = create_client()  # Uses AWS credentials automatically

# Identical to boto3 S3 API - just works with 99% compression!
response = client.put_object(
    Bucket='releases',
    Key='v2.0.0/my-app.zip',
    Body=open('my-app-v2.0.0.zip', 'rb')
)
print(f"Stored with ETag: {response['ETag']}")

# Standard boto3 get_object - handles delta reconstruction automatically
response = client.get_object(Bucket='releases', Key='v2.0.0/my-app.zip')
with open('downloaded.zip', 'wb') as f:
    f.write(response['Body'].read())

# Smart list_objects with optimized performance
response = client.list_objects(Bucket='releases', Prefix='v2.0.0/')
for obj in response['Contents']:
    print(f"{obj['Key']}: {obj['Size']} bytes")

# Paginated listing for large buckets
response = client.list_objects(Bucket='releases', MaxKeys=100)
while response.get('IsTruncated'):
    for obj in response['Contents']:
        print(obj['Key'])
    response = client.list_objects(
        Bucket='releases',
        MaxKeys=100,
        ContinuationToken=response.get('NextContinuationToken')
    )

# Delete and inspect objects
client.delete_object(Bucket='releases', Key='old-version.zip')
client.head_object(Bucket='releases', Key='v2.0.0/my-app.zip')

Bucket Management

No boto3 required! DeltaGlider provides complete bucket management:

from deltaglider import create_client

client = create_client()

# Create buckets
client.create_bucket(Bucket='my-releases')

# Create bucket in specific region (AWS only)
client.create_bucket(
    Bucket='my-regional-bucket',
    CreateBucketConfiguration={'LocationConstraint': 'us-west-2'}
)

# List all buckets
response = client.list_buckets()
for bucket in response['Buckets']:
    print(f"{bucket['Name']} - {bucket['CreationDate']}")

# Delete bucket (must be empty)
client.delete_bucket(Bucket='my-old-bucket')

See examples/bucket_management.py for complete example.

Simple API (Alternative)

For simpler use cases, DeltaGlider also provides a streamlined API:

from deltaglider import create_client

client = create_client()

# Simple upload with automatic compression detection
summary = client.upload("my-app-v2.0.0.zip", "s3://releases/v2.0.0/")
print(f"Compressed from {summary.original_size_mb:.1f}MB to {summary.stored_size_mb:.1f}MB")
print(f"Saved {summary.savings_percent:.0f}% storage space")

# Simple download with automatic delta reconstruction
client.download("s3://releases/v2.0.0/my-app-v2.0.0.zip", "local-app.zip")

Real-World Examples

Software Release Storage

from deltaglider import create_client

client = create_client()

# Upload multiple versions
versions = ["v1.0.0", "v1.0.1", "v1.0.2", "v1.1.0"]
for version in versions:
    with open(f"dist/my-app-{version}.zip", 'rb') as f:
        response = client.put_object(
            Bucket='releases',
            Key=f'{version}/my-app-{version}.zip',
            Body=f,
            Metadata={'version': version, 'build': 'production'}
        )

    # Check compression stats (DeltaGlider extension)
    if 'DeltaGliderInfo' in response:
        info = response['DeltaGliderInfo']
        if info.get('IsDelta'):
            print(f"{version}: Stored as {info['StoredSizeMB']:.1f}MB delta "
                  f"(saved {info['SavingsPercent']:.0f}%)")
        else:
            print(f"{version}: Stored as reference ({info['OriginalSizeMB']:.1f}MB)")

# Result:
# v1.0.0: Stored as reference (100.0MB)
# v1.0.1: Stored as 0.2MB delta (saved 99.8%)
# v1.0.2: Stored as 0.3MB delta (saved 99.7%)
# v1.1.0: Stored as 5.2MB delta (saved 94.8%)

Automated Database Backup

from datetime import datetime
from deltaglider import create_client

client = create_client(endpoint_url="http://minio.internal:9000")

def backup_database():
    """Daily database backup with automatic deduplication."""
    date = datetime.now().strftime("%Y%m%d")
    dump_file = f"backup-{date}.sql.gz"

    # Upload using boto3-compatible API
    with open(dump_file, 'rb') as f:
        response = client.put_object(
            Bucket='backups',
            Key=f'postgres/{date}/{dump_file}',
            Body=f,
            Tagging='type=daily&database=production',
            Metadata={'date': date, 'source': 'production'}
        )

    # Check compression effectiveness
    if 'DeltaGliderInfo' in response:
        info = response['DeltaGliderInfo']
        if info['DeltaRatio'] > 0.1:
            print(f"Warning: Low compression ({info['SavingsPercent']:.0f}%), "
                  "database might have significant changes")
        print(f"Backup stored: {info['StoredSizeMB']:.1f}MB "
              f"(compressed from {info['OriginalSizeMB']:.1f}MB)")

Performance & Benchmarks

Real-World Results

Testing with 513 Elasticsearch plugin releases (82.5MB each):

Original size:       42.3 GB
DeltaGlider size:    115 MB
Compression:         99.7%
Upload speed:        3-4 files/second
Download speed:      <100ms reconstruction

The Math

For N versions of a S MB file with D% difference between versions:

Traditional S3: N × S MB DeltaGlider: S + (N-1) × S × D% MB

Example: 100 versions of 100MB files with 1% difference:

Traditional: 10,000 MB
DeltaGlider: 199 MB
Savings: 98%

Comparison

Solution	Compression	Speed	Integration	Cost
DeltaGlider	99%+	Fast	Drop-in	Open source
S3 Versioning	0%	Native	Built-in	$$ per version
Deduplication	30-50%	Slow	Complex	Enterprise $$$
Git LFS	Good	Slow	Git-only	$ per GB

Architecture & Technical Deep Dive

Why xdelta3 Excels at Archive Compression

Traditional diff algorithms (like diff or git diff) work line-by-line on text files. Binary diff tools like bsdiff or courgette are optimized for executables. But xdelta3 is uniquely suited for compressed archives because:

Block-level matching: xdelta3 uses a rolling hash algorithm to find matching byte sequences at any offset, not just line boundaries. This is crucial for archives where small file changes can shift all subsequent byte positions.
Large window support: xdelta3 can use reference windows up to 2GB, allowing it to find matches even when content has moved significantly within the archive. Other delta algorithms typically use much smaller windows (64KB-1MB).
Compression-aware: When you update one file in a ZIP/TAR archive, the archive format itself remains largely identical - same compression dictionary, same structure. xdelta3 preserves these similarities while other algorithms might miss them.
Format agnostic: Unlike specialized tools (e.g., courgette for Chrome updates), xdelta3 works on raw bytes without understanding the file format, making it perfect for any archive type.

Real-World Example

When you rebuild a JAR file with one class changed:

Text diff: 100% different (it's binary data!)
bsdiff: ~30-40% of original size (optimized for executables, not archives)
xdelta3: ~0.1-1% of original size (finds the unchanged parts regardless of position)

This is why DeltaGlider achieves 99%+ compression on versioned archives - xdelta3 can identify that 99% of the archive structure and content remains identical between versions.

System Architecture

DeltaGlider uses a clean hexagonal architecture:

┌─────────────┐     ┌──────────────┐     ┌─────────────┐
│   Your App  │────▶│ DeltaGlider  │────▶│  S3/MinIO   │
│   (CLI/SDK) │     │    Core      │     │   Storage   │
└─────────────┘     └──────────────┘     └─────────────┘
                           │
                    ┌──────▼───────┐
                    │ Local Cache  │
                    │ (References) │
                    └──────────────┘

Key Components:

Binary diff engine: xdelta3 for optimal compression
Intelligent routing: Automatic file type detection
Integrity verification: SHA256 on every operation
Local caching: Fast repeated operations
Zero dependencies: No database, no manifest files

When to Use DeltaGlider

✅ Perfect for:

Software releases and versioned artifacts
Container images and layers
Database backups and snapshots
Machine learning model checkpoints
Game assets and updates
Any versioned binary data

❌ Not ideal for:

Already compressed unique files
Streaming or multimedia files
Frequently changing unstructured data
Files smaller than 1MB

Migration from AWS CLI

Migrating from aws s3 to deltaglider is as simple as changing the command name:

AWS CLI	DeltaGlider	Compression Benefit
`aws s3 cp file.zip s3://bucket/`	`deltaglider cp file.zip s3://bucket/`	✅ 99% for similar files
`aws s3 cp -r dir/ s3://bucket/`	`deltaglider cp -r dir/ s3://bucket/`	✅ 99% for archives
`aws s3 ls s3://bucket/`	`deltaglider ls s3://bucket/`	-
`aws s3 rm s3://bucket/file`	`deltaglider rm s3://bucket/file`	-
`aws s3 sync dir/ s3://bucket/`	`deltaglider sync dir/ s3://bucket/`	✅ 99% incremental

Migrating Existing S3 Buckets

DeltaGlider provides a dedicated migrate command to compress your existing S3 data:

# Migrate an entire bucket
deltaglider migrate s3://old-bucket/ s3://compressed-bucket/

# Migrate a prefix (preserves prefix structure by default)
deltaglider migrate s3://bucket/releases/ s3://bucket/archive/
# Result: s3://bucket/archive/releases/ contains the files

# Migrate without preserving source prefix
deltaglider migrate --no-preserve-prefix s3://bucket/v1/ s3://bucket/archive/
# Result: Files go directly into s3://bucket/archive/

# Preview migration (dry run)
deltaglider migrate --dry-run s3://old/ s3://new/

# Skip confirmation prompt
deltaglider migrate --yes s3://old/ s3://new/

# Exclude certain file patterns
deltaglider migrate --exclude "*.log" s3://old/ s3://new/

Key Features:

Resume Support: Migration automatically skips files that already exist in the destination
Progress Tracking: Shows real-time migration progress and statistics
Safety First: Interactive confirmation shows file count before starting
EC2 Cost Optimization: Automatically detects EC2 instance region and warns about cross-region charges
- ✅ Green checkmark when regions align (no extra charges)
- ℹ️ INFO when auto-detected mismatch (suggests optimal region)
- ⚠️ WARNING when user explicitly set wrong --region (expect data transfer costs)
- Disable with DG_DISABLE_EC2_DETECTION=true if needed
AWS Region Transparency: Displays the actual AWS region being used
Prefix Preservation: By default, source prefix is preserved in destination (use --no-preserve-prefix to disable)
S3-to-S3 Transfer: Both regular S3 and DeltaGlider buckets supported

Prefix Preservation Examples:

s3://src/data/ → s3://dest/ creates s3://dest/data/
s3://src/a/b/c/ → s3://dest/x/ creates s3://dest/x/c/
Use --no-preserve-prefix to place files directly in destination without the source prefix

The migration preserves all file names and structure while applying DeltaGlider's compression transparently.
