Using Amazon DocumentDB (with MongoDB compatibility) as a source for AWS DMS

To Nha Notes | Oct. 7, 2022, 6:01 p.m.

AWS DMS supports Amazon DocumentDB (with MongoDB compatibility) versions 3.6 and 4.0 as a database source. Using Amazon DocumentDB as a source, you can migrate data from one Amazon DocumentDB cluster to another Amazon DocumentDB cluster. You can also migrate data from an Amazon DocumentDB cluster to one of the other target endpoints supported by AWS DMS.

Configuring CDC for an Amazon DocumentDB cluster

To use ongoing replication or CDC with Amazon DocumentDB, AWS DMS requires access to the Amazon DocumentDB cluster's change streams. For a description of the time-ordered sequence of update events in your cluster's collections and databases, see Using change streams in the Amazon DocumentDB Developer Guide.

Authenticate to your Amazon DocumentDB cluster using the MongoDB shell. Then run the following command to enable change streams.

db.adminCommand({modifyChangeStreams: 1, database: "DB_NAME", collection: "", enable: true});

Connecting to Amazon DocumentDB using TLS

aws dms import-certificate \ --certificate-identifier docdb-cert \ --certificate-pem file://./rds-combined-ca-bundle.pem

To configure an Amazon DocumentDB source endpoint using the AWS CLI

aws dms create-endpoint \
           --endpoint-identifier a_memorable_name \
           --endpoint-type source \
           --engine-name docdb \
           --username value \
           --password value \
           --server-name servername_where_database_endpoint_resides \
           --port 27017 \
           --database-name name_of_endpoint_database
