S3 Inventory Report Structure

This reference outlines the expected folder layout and file format for Amazon S3 inventory reports used by Atlan’s S3 crawler when running inventory-based ingestion.

important

The crawler supports a single destination bucket, with an optional prefix, to store all inventory reports from multiple source buckets.

Folder structure

To enable successful inventory-based crawling, your destination bucket must follow this structure once inventory reports are generated:

📦 <destination-bucket>/
├── [📁 <optional-prefix>/] (applies to all buckets)
│   ├── 📁 <source-bucket-1>/
│   │   ├── 📁 <inventory-config-1>/
│   │   │   ├── 📁 <YYYY-MM-DDTHH-MM-Z>/ (timestamp folders)
│   │   │   │   └── 📄 manifest.json
│   │   │   └── 📁 data/ (CSV or gzipped files)
│   │   │       └── 📄 <inventory-file>.csv.gz
│   │   └── 📁 <inventory-config-2>/
│   └── 📁 <source-bucket-2>/
└── ...

Required	Component	Description	Example
✅	Destination bucket	Single S3 bucket to store all inventory reports	atlan-inventory-reports
❌	Prefix	Folder prefix to organize reports (same for all source buckets)	inventory-reports
✅	Source bucket folder	Folder named after each source bucket	source-bucket-1
✅	Inventory config folder	Folder named after the inventory configuration	daily-inventory
✅	Timestamp folder	Folder with report generation timestamp	2024-01-16T00-00Z
✅	Manifest file	manifest.json containing report metadata	manifest.json
✅	Data folder	Folder containing compressed inventory files	data
✅	Inventory files	.csv.gz or .parquet files with actual data	inventory-2024-01-16-00-00Z.csv.gz
