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.

Supported capabilities

This Presto connector is supported for the following capabilities:

Supported capabilities IR
Copy activity (source/-) ① ②
Lookup activity ① ②

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.

Getting started

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

Create a linked service to Presto using UI

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:

  2. Search for Presto and select the Presto connector.

    Screenshot of the Presto connector.

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

    Screenshot of linked service configuration for Presto.

Connector configuration details

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

Linked service properties

The following properties are supported for Presto linked service:

Property Description Required
type The type property must be set to: Presto Yes
host The IP address or host name of the Presto server. (e.g. 192.168.222.160) Yes
serverVersion The version of the Presto server. (e.g. 0.148-t) Yes
catalog The catalog context for all request against the server. Yes
port The TCP port that the Presto server uses to listen for client connections. The default value is 8080. No
authenticationType The authentication mechanism used to connect to the Presto server.
Allowed values are: Anonymous, LDAP		 Yes
username The user name used to connect to the Presto server. No
password The password corresponding to the user name. Mark this field as a SecureString to store it securely, or reference a secret stored in Azure Key Vault. No
enableSsl Specifies whether the connections to the server are encrypted using TLS. The default value is false. No
trustedCertPath The full path of the .pem file containing trusted CA certificates for verifying the server when connecting over TLS. This property can only be set when using TLS on self-hosted IR. The default value is the cacerts.pem file installed with the IR. No
useSystemTrustStore Specifies whether to use a CA certificate from the system trust store or from a specified PEM file. The default value is false. No
allowHostNameCNMismatch Specifies whether to require a CA-issued TLS/SSL certificate name to match the host name of the server when connecting over TLS. The default value is false. No
allowSelfSignedServerCert Specifies whether to allow self-signed certificates from the server. The default value is false. No
timeZoneID The local time zone used by the connection. Valid values for this option are specified in the IANA Time Zone Database. The default value is the system time zone. No

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"
        }
    }
}

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 Presto dataset.

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

Property Description Required
type The type property of the dataset must be set to: PrestoObject Yes
schema Name of the schema. No (if "query" in activity source is specified)
table Name of the table. No (if "query" in activity source is specified)
tableName Name of the table with schema. This property is supported for backward compatibility. Use schema and table for new workload. No (if "query" in activity source is specified)

Example

{
    "name": "PrestoDataset",
    "properties": {
        "type": "PrestoObject",
        "typeProperties": {},
        "schema": [],
        "linkedServiceName": {
            "referenceName": "<Presto 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 Presto source.

Presto as 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:

Property Description Required
type The type property of the copy activity source must be set to: PrestoSource Yes
query Use the custom SQL query to read data. For example: "SELECT * FROM MyTable". No (if "tableName" in dataset is specified)

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>"
            }
        }
    }
]
