CAST supports Amazon DocumentDB via its com.castsoftware.nosqljava extension. As Amazon DocumentDB is MongoDB compatible, supported operations, objects and links are identical to those listed in MongoDB.
Supported Amazon DocumentDB versions
| Library | Version | Supported |
|---|---|---|
| Amazon Document Db | Up to: 4.0 |  |
Amazon DocumentDB Identification
The below mentioned objects in MongoDB have properties to indicate whether the object is of type MongoDB or Amazon DocumentDB:
Object | Type of Property Value | Possible Value(s) | Meaning |
|---|---|---|---|
| Java MongoDB collection | Integer | 1 | The collection object is of type Amazon DocumentDB |
| Java MongoDB collection | Integer | 0 | The collection object is of type MongoDB |
| Java unknown MongoDB collection | Integer | 1 | The collection object is of type Amazon DocumentDB |
| Java unknown MongoDB collection | Integer | 0 | The collection object is of type MongoDB |
