HCA Smart-Sync

Intelligent S3 data synchronization for HCA Atlas source datasets and integrated objects.

• SHA256 verification - Research-grade data integrity
• Manifest generation - Automatic upload manifests
• Progress tracking - Real-time upload progress
• Environment support - Separate prod and dev buckets
• Dry run mode - Preview changes before uploading

Requirements

• Python 3.10+
• AWS CLI configured with appropriate profiles
• S3 access to HCA Atlas buckets

Installation

Install using pipx (recommended):

pipx install hca-smart-sync

Quick Start

First Time Setup

Configure default settings (optional but recommended):

hca-smart-sync config init
# Enter your default AWS profile and atlas name

Basic Usage

# Sync source datasets for gut atlas
hca-smart-sync sync gut-v1 source-datasets --profile my-profile

# Sync integrated objects for immune atlas
hca-smart-sync sync immune-v1 integrated-objects --profile my-profile

# Dry run to preview changes
hca-smart-sync sync gut-v1 source-datasets --profile my-profile --dry-run

Using Config Defaults

Once you've configured defaults, you can omit the atlas:

# File type only (uses config for atlas and profile)
hca-smart-sync sync source-datasets

# Or integrated objects
hca-smart-sync sync integrated-objects

# Override config atlas, use config profile
hca-smart-sync sync immune-v1 source-datasets

Flexible Argument Order

The tool accepts arguments in two ways:

# Atlas first, then file type
hca-smart-sync sync gut-v1 source-datasets

# File type first (uses config for atlas)
hca-smart-sync sync source-datasets

Note: File type is always required - you must specify either source-datasets or integrated-objects.

Available Options

• --profile TEXT - AWS profile to use (uses config default if not specified)
• --dry-run - Preview changes without uploading
• --verbose - Show detailed output
• --force - Force upload even if file content is unchanged
• --local-path TEXT - Custom local directory (defaults to current directory)
