Access Live Presto Data in TIBCO Data Virtualization
Use the CData TIBCO DV Adapter for Presto to create a Presto data source in TIBCO Data Virtualization Studio and gain access to live Presto data from your TDV Server.
TIBCO Data Virtualization (TDV) is an enterprise data virtualization solution that orchestrates access to multiple and varied data sources. When paired with the CData TIBCO DV Adapter for Presto, you get federated access to live Presto data directly within TIBCO Data Virtualization. This article walks through deploying an adapter and creating a new data source based on Presto.
With built-in optimized data processing, the CData TIBCO DV Adapter offers unmatched performance for interacting with live Presto data. When you issue complex SQL queries to Presto, the adapter pushes supported SQL operations, like filters and aggregations, directly to Presto. Its built-in dynamic metadata querying allows you to work with and analyze Presto data using native data types.
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
Deploy the Presto TIBCO DV Adapter
In a console, navigate to the bin folder in the TDV Server installation directory. If there is a current version of the adapter installed, you will need to undeploy it.
.\server_util.bat -server localhost -user admin -password ******** -undeploy -version 1 -name Presto
Extract the CData TIBCO DV Adapter to a local folder and deploy the JAR file (tdv.presto.jar) to the server from the extract location.
.\server_util.bat -server localhost -user admin -password ******** -deploy -package /PATH/TO/tdv.presto.jar
You may need to restart the server to ensure the new JAR file is loaded properly, which can be accomplished by running the composite.bat script located at: C:\Program Files\TIBCO\TDV Server <version>\bin. Note that reauthenticating to the TDV Studio is required after restarting the server.
Sample Restart Call
.\composite.bat monitor restartOnce you deploy the adapter, you can create a new data source in TDV Studio for Presto.
Create a Presto Data Source in TDV Studio
With the CData TIBCO DV Adapter for Presto, you can easily create a data source for Presto and introspect the data source to add resources to TDV.
Create the Data Source
- Right-click on the folder you wish to add the data source to and select New -> New Data Source.
- Scroll until you find the adapter (e.g. Presto) and click Next.
- Name the data source (e.g. CData Presto Source).
Fill in the required connection properties.
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 & Close.
Introspect the Data Source
Once the data source is created, you can introspect the data source by right-clicking and selecting Open. In the dashboard, click Add/Remove Resources and select the Tables, Views, and Stored Procedures to include as part of the data source. Click Next and Finish to add the selected Presto tables, views, and stored procedures as resources.
After creating and introspecting the data source, you are ready to work with Presto data in TIBCO Data Virtualization just like you would any other relational data source. You can create views, query using SQL, publish the data source, and more.
