Connect to Presto Data in ACL Analytics
Connect to Presto data via CData Connect Cloud in ACL Analytics to run your data analysis workflows with real-time access to Presto data.
ACL Analytics, part of Diligent HighBond, is a powerful data analysis software primarily used for audit, risk management, and compliance. It enables professionals to examine and analyze large volumes of data to identify anomalies, trends, and potential risks or fraudulent activities.
CData Connect Cloud offers a dedicated cloud-to-cloud interface for Presto, enabling analytics directly from live Presto data within ACL Analytics, all without the need for data replication to a native database. With its inherent optimized data processing capabilities, CData Connect Cloud efficiently channels all supported SQL operations, including filters and JOINs, directly to Presto. This leverages server-side processing to swiftly deliver the requested Presto data.
About Presto Data Integration
Accessing and integrating live data from Trino and Presto SQL engines has never been easier with CData. Customers rely on CData connectivity to:
- Access data from Trino v345 and above (formerly PrestoSQL) and Presto v0.242 and above (formerly PrestoDB)
- Read and write access all of the data underlying your Trino or Presto instances
- Optimized query generation for maximum throughput.
Presto and Trino allow users to access a variety of underlying data sources through a single endpoint. When paired with CData connectivity, users get pure, SQL-92 access to their instances, allowing them to integrate business data with a data warehouse or easily access live data directly from their preferred tools, like Power BI and Tableau.
In many cases, CData's live connectivity surpasses the native import functionality available in tools. One customer was unable to effectively use Power BI due to the size of the datasets needed for reporting. When the company implemented the CData Power BI Connector for Presto they were able to generate reports in real-time using the DirectQuery connection mode.
Getting Started
Configure Presto Connectivity for ACL Analytics
Connectivity to Presto from ACL Analytics is made possible through CData Connect Cloud. To work with Presto data from ACL Analytics, we start by creating and configuring a Presto connection in CData Connect Cloud.
- Log into Connect Cloud, click Sources, and then click Add Connection
- Select "Presto" from the Add Connection panel
- Enter the necessary authentication properties to connect to Presto.
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.
- Click Create & Test
-
Navigate to the Permissions tab in the Add Presto Connection page and update the User-based permissions.
Add a Personal Access Token
When connecting to Connect Cloud through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect Cloud. It is best practice to create a separate PAT for each service to maintain granularity of access.
- Click on the Gear icon () at the top right of the Connect Cloud app to open the settings page.
- On the Settings page, go to the Access Tokens section and click Create PAT.
-
Give the PAT a name and click Create.
- The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
With the connection configured and a PAT generated, you are ready to connect to Presto data from ACL Analytics.
Connect to Presto from ACL Analytics
The steps below outline connecting to CData Connect Cloud from ACL Analytics to create a new Presto data source. The CData Connect Cloud Virtual SQL Server allows you to establish a connection to your data from integration tools that support connections to SQL servers. The Virtual SQL Server mimics the behavior of a traditional SQL server, and it supports a range of query options.
- With your Analytics File open, select 'Import' --> 'Database and application'
- Create a new SQL Server connection
- Set the connection information
- Server: tds.cdata.com
- Port: 14333
- Auth Scheme: Password
- Username: a Connect Cloud user, for example, [email protected]
- Password: the PAT for the above Connect Cloud user
- Database: the name of your Presto connection, for example, Presto1
- Click "Test Connection"
- Click "OK"
- You are now ready to work with your Presto data in ACL Analytics!
