Connect to Presto Data in RunMyProcess through Connect Cloud

Akorbi Digital RunMyProcess makes it easy to create applications for complex business applications, such as budget application and contract management. CData Connect Cloud creates a live connection to Presto and can be used to generate an OData API (natively supported in RunMyProcess) for Presto. By pairing RunMyProcess with CData Connect Cloud, you get true cloud-to-cloud connectivity to all your SaaS and cloud-based Big Data and NoSQL sources - no need to migrate your data or write your own integrations. Simply connect to Connect Cloud from RunMyProcess as you would any other REST service and get instant, live access to your Presto data.

In this article, we walk through connecting to Presto from CData Connect Cloud and accessing Presto data through an OData feed in RunMyProcess.

Getting Started

---

Connect to Presto from RunMyProcess

To work with live Presto data in RunMyProcess, we need to connect to Presto from Connect Cloud, provide user access to the connection, and create OData endpoints for the Presto data.

(Optional) Add a New Connect Cloud User

As needed, create Users to connect to Presto through Connect Cloud.

1. Navigate to the Users page and click Invite Users
2. Enter the new user's email address and click Send to invite the user
3. You can review and edit users from the Users page

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

Connect to Presto from Connect Cloud

CData Connect Cloud uses a straightforward, point-and-click interface to connect to data sources.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "Presto" from the Add Connection panel
3. Enter the necessary authentication properties to connect to Presto.

   Set the Server and Port connection properties to connect, in addition to any authentication properties that may be required.

   To enable TLS/SSL, set UseSSL to true.

   Authenticating with LDAP

   In order to authenticate with LDAP, set the following connection properties:

   • AuthScheme: Set this to LDAP.
   • User: The username being authenticated with in LDAP.
   • Password: The password associated with the User you are authenticating against LDAP with.

   Authenticating with Kerberos

   In order to authenticate with KERBEROS, set the following connection properties:

   • AuthScheme: Set this to KERBEROS.
   • KerberosKDC: The Kerberos Key Distribution Center (KDC) service used to authenticate the user.
   • KerberosRealm: The Kerberos Realm used to authenticate the user with.
   • KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.
   • KerberosKeytabFile: The Keytab file containing your pairs of Kerberos principals and encrypted keys.
   • User: The user who is authenticating to Kerberos.
   • Password: The password used to authenticate to Kerberos.
   
4. Click Create & Test
5. Navigate to the Permissions tab in the Add Presto Connection page and update the User-based permissions.

Configure Presto Endpoints for RunMyProcess

After connecting to Presto, create a workspace and virtual dataset for your desired table(s).

1. Navigate to the Virtual Datasets page and click Add to create a new Workspace (or select an existing workspace).
2. Click Add to add new assets to the Workspace.
3. Select the Presto connection (e.g. Presto1) and click Next.
4. Select the table(s) you wish to work with and click Confirm.
5. Make note of the OData Service URL for your workspace, e.g. https://cloud.cdata.com/api/odata/{workspace_name}

Sample URLs for OData Feeds

Once you have configured a connection to Presto, created a user, and created OData endpoints in Connect Cloud, you can access OData feeds for Presto data. Below, you will see the URLs to access tables and the list of tables. For information on accessing the tables, you can navigate to the OData page for Connect Cloud. For the URLs, you will need the URL of Connect Cloud: https://cloud.cdata.com/api/odata/{workspace_name}.

As with standard OData feeds, if you wish to limit the fields returned, you can add a $select parameter to the query, along with other standard OData URL parameters, such as $filter, $orderby, $skip, and $top. See the help documentation for more information on supported OData queries.

With the connection and Workspace configured, you are ready to connect to Presto data from RunMyProcess.

Retrieve Presto Data from RunMyProcess DigitalSuite Studio

With the connection to Presto and OData endpoints created, we are ready to add Presto data to RunMyProcess for Retrieval.

Create a Provider

1. Log into RunMyProcess and open DigitalSuite Studio.
2. Click Resources to bring up the Resources page, then select then the CONNECTORS tab.
3. Click the + (New Provider) button to create a new provider, choose the account to use, then click Confirm.
4. In the provider settings page, configure the following properties.
   • URL: Set the OData endpoint in the Connect Cloud OData page: https://cloud.cdata.com/api/odata/{workspace_name}.
   • Authentication Schema: Select Login/Password.
   • Login: Specify a CData Connect Cloud username (e.g. [email protected]).
   • Password: Specify the PAT of the Connect Cloud user.
   
5. Fill in the same properties in the ACCEPTANCE and TEST tabs. Note: You can copy the configured settings by clicking 'Copy this configuration button,' then pasting the content in the new tab by clicking 'Paste previously copied configuration.'
6. Click Save to save the properties.

Retrieve Presto Data by Creating a Connector

1. In the CONNECTORS tab, click the button with three dots to create the provider, then select Add connector from the menu.
2. In the following page, set Connector URL to the OData endpoint configured in Connect Cloud (e.g. https://cloud.cdata.com/api/odata/{workspace_name})
3. Click Save then Launch to test the connector execution. Click Launch test to execute. The process is successful if you get the JSON response of your configured table information.
