**Data Store Crawling**:
- **Admin Path**: Crawler > Data Store
- **Supports**: Databases (via JDBC), CSV files, custom plugins
- **Features**: Incremental updates, custom field mapping

1. **Directory Leases**: Extend lease support for directories
2. **Lease Key Persistence**: Save lease keys for reconnection
