File System Provider

The File System Provider (the "FileStorageProvider" section) requires the RootDirectory parameter, which specifies the root directory for storing files.

The File System Provider:

• Uses a structured directory hierarchy based on event timestamp and transaction identifier.

• File naming convention includes event identifier and property name.

• Implements error handling and logging.

• Error handling: The implementation includes error handling and logging mechanisms.

• Data management: The hierarchical directory structure (year‑month/transaction identifier) is designed to help with data aging scenarios, including archiving and bulk deleting historical data.

Directory Structure

The hierarchical directory structure (year‑month/transaction identifier), shown in the following example, is designed as an aid to archiving and aging historical data.

RootDirectory\
├── YYYY-MM\
│   ├── TransactionID1\
│   │   ├── [EventID1]__PropertyName1.blob
│   │   └── [EventID1]__PropertyName2.slob
│   └── TransactionID2\
│       ├── [EventID2]__PropertyName1.blob
│       └── [EventID2]__PropertyName2.slob
└── YYYY-MM\
└── ...
