Copy data from Presto using Azure Data Factory or Synapse Analytics

APPLIES TO: Azure Data Factory Azure Synapse Analytics

This article outlines how to use the Copy Activity in an Azure Data Factory or Synapse Analytics pipeline to copy data from Presto. It builds on the copy activity overview article that presents a general overview of copy activity.

This Presto connector is supported for the following capabilities:

① Azure integration runtime ② Self-hosted integration runtime

For a list of data stores that are supported as sources/sinks by the copy activity, see the Supported data stores table.

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

To perform the Copy activity with a pipeline, you can use one of the following tools or SDKs:

• The Copy Data tool
• The Azure portal
• The .NET SDK
• The Python SDK
• Azure PowerShell
• The REST API
• The Azure Resource Manager template

Use the following steps to create a linked service to Presto in the Azure portal UI.

1. Browse to the Manage tab in your Azure Data Factory or Synapse workspace and select Linked Services, then click New:

   • Azure Data Factory
   • Azure Synapse

   

2. Search for Presto and select the Presto connector.

   

3. Configure the service details, test the connection, and create the new linked service.

   

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

The Presto connector now supports version 2.0 (Preview). Refer to this section to upgrade your Presto connector version from version 1.0. For the property details, see the corresponding sections.

• Version 2.0 (Preview)
• Version 1.0

The Presto linked service supports the following properties when apply version 2.0 (Preview):

Example:

{
    "name": "PrestoLinkedService",
    "properties": {
        "type": "Presto",
        "version" : "2.0",
        "typeProperties": {
            "host" : "<host>",
            "catalog" : "<catalog>",
            "port" : 8443,
            "authenticationType" : "LDAP",
            "username" : "<username>",
            "password": {
                 "type": "SecureString",
                 "value": "<password>"
            },
            "enableSsl": true,
            "enableServerCertificateValidation": true,
            "timeZoneID" : ""
        }
    }
}

The Presto linked service supports the following properties when apply version 1.0:

Example:

{
    "name": "PrestoLinkedService",
    "properties": {
        "type": "Presto",
        "typeProperties": {
            "host" : "<host>",
            "serverVersion" : "0.148-t",
            "catalog" : "<catalog>",
            "port" : "<port>",
            "authenticationType" : "LDAP",
            "username" : "<username>",
            "password": {
                 "type": "SecureString",
                 "value": "<password>"
            },
            "timeZoneID" : "Europe/Berlin"
        }
    }
}

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 Presto dataset.

To copy data from Presto, set the type property of the dataset to PrestoObject. The following properties are supported:

Example

{
    "name": "PrestoDataset",
    "properties": {
        "type": "PrestoObject",
        "typeProperties": {},
        "schema": [],
        "linkedServiceName": {
            "referenceName": "<Presto linked service name>",
            "type": "LinkedServiceReference"
        }
    }
}

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 Presto source.

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

Example:

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

When you copy data from Presto, the following mappings apply from Presto's data types to the internal data types used by the service. To learn about how the copy activity maps the source schema and data type to the sink, see Schema and data type mappings.

To learn details about the properties, check Lookup activity.

Here are steps that help you upgrade the Presto connector:

1. In Edit linked service page, select version 2.0 (Preview) and configure the linked service by referring to linked service version 2.0 (Preview) properties.

2. The data type mapping for the Presto linked service version 2.0 (Preview) is different from that for the version 1.0. To learn the latest data type mapping, see Data type mapping for Presto.

The Presto connector version 2.0 (Preview) offers new functionalities and is compatible with most features of version 1.0. The following table shows the feature differences between version 2.0 (Preview) and version 1.0.
