Amazon DocumentDB Identification

The below mentioned objects have properties to indicate whether the object is of type MongoDB or Amazon DocumentDB.


Property Description

Type of Property Value

Possible Value(s)


Java MongoDB collectionIs an Amazon DocumentDB collection?Integer


The collection object is of type Amazon DocumentDB

0The collection object is of type MongoDB
Java unknown MongoDB collectionIs an Amazon DocumentDB collection?Integer


The collection object is of type Amazon DocumentDB

0The collection object is of type MongoDB

What results can you expect?

Once the analysis/snapshot generation is complete, you can view the results in the normal manner (for example via CAST Enlighten). Some examples are shown below.

  • There will be no connection object created.
  • Better resolution for database and collection name
  • Support for CRUD APIs com.mongodb.client.MongoCollection


  • For the method 'mapReduce' the type of link produced is 'useLink' as its type is not determined
  • If collection name is not resolved in the CRUD API, then link is created with unknown collection object.
  • Setting of properties related to Amazon DocumentDB identification depends on proper resolution of connection string.
  • No labels
