Copy data from Couchbase using Azure Data Factory (Preview)

This article outlines how to use the Copy Activity in Azure Data Factory to copy data from Couchbase. It builds on the copy activity overview article that presents a general overview of copy activity.

Important

This connector is currently in preview. You can try it out and give us feedback. If you want to take a dependency on preview connectors in your solution, please contact Azure support.

Supported capabilities

You can copy data from Couchbase to any supported sink data store. For a list of data stores that are supported as sources/sinks by the copy activity, see the Supported data stores table.

Azure Data Factory provides a built-in driver to enable connectivity, therefore you don't need to manually install any driver using this connector.

Getting started

You can use one of the following tools or SDKs to use Copy Activity with a pipeline. Select a link for step-by-step instructions:

The following sections provide details about properties that are used to define Data Factory entities specific to Couchbase connector.

Linked service properties

The following properties are supported for Couchbase linked service:

Property Description Required
type The type property must be set to: Couchbase Yes
connectionString An ODBC connection string to connect to Couchbase. Mark this field as a SecureString to store it securely in Data Factory, or reference a secret stored in Azure Key Vault. Yes
connectVia The Integration Runtime to be used to connect to the data store. You can use Self-hosted Integration Runtime or Azure Integration Runtime (if your data store is publicly accessible). If not specified, it uses the default Azure Integration Runtime. No

Example:

{
    "name": "CouchbaseLinkedService",
    "properties": {
        "type": "Couchbase",
        "typeProperties": {
            "connectionString": {
                 "type": "SecureString",
                 "value": "Server=<server>; Port=<port>;AuthMech=1;CredString=[{\"user\": \"JSmith\", \"pass\":\"access123\"}, {\"user\": \"Admin\", \"pass\":\"simba123\"}];"
            }
        },
        "connectVia": {
            "referenceName": "<name of Integration Runtime>",
            "type": "IntegrationRuntimeReference"
        }
    }
}

Dataset properties

For a full list of sections and properties available for defining datasets, see the datasets article. This section provides a list of properties supported by Couchbase dataset.

To copy data from Couchbase, set the type property of the dataset to CouchbaseTable. There is no additional type-specific property in this type of dataset.

Example

{
    "name": "CouchbaseDataset",
    "properties": {
        "type": "CouchbaseTable",
        "linkedServiceName": {
            "referenceName": "<Couchbase linked service name>",
            "type": "LinkedServiceReference"
        }
    }
}

Copy activity properties

For a full list of sections and properties available for defining activities, see the Pipelines article. This section provides a list of properties supported by Couchbase source.

CouchbaseSource as source

To copy data from Couchbase, set the source type in the copy activity to CouchbaseSource. The following properties are supported in the copy activity source section:

Property Description Required
type The type property of the copy activity source must be set to: CouchbaseSource Yes
query Use the custom SQL query to read data. For example: "SELECT * FROM MyTable". Yes

Example:

"activities":[
    {
        "name": "CopyFromCouchbase",
        "type": "Copy",
        "inputs": [
            {
                "referenceName": "<Couchbase input dataset name>",
                "type": "DatasetReference"
            }
        ],
        "outputs": [
            {
                "referenceName": "<output dataset name>",
                "type": "DatasetReference"
            }
        ],
        "typeProperties": {
            "source": {
                "type": "CouchbaseSource",
                "query": "SELECT * FROM MyTable"
            },
            "sink": {
                "type": "<sink type>"
            }
        }
    }
]
