Use CData Connect Cloud to connect to and query live Presto data from HeidiSQL.
HeidiSQL is an open-source database administration tool that natively supports MariaDB, MySQL, SQL Server, and PostgreSQL. When paired with CData Connect Cloud, HediSQL reach extends to include access to live Presto data. This article demonstrates how to connect to Presto using Connect Cloud and query Presto data in HeidiSQL.
CData Connect Cloud provides a pure SQL Server interface for Presto, allowing you to query data from Presto without replicating the data to a natively supported database. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc.) directly to Presto, leveraging server-side processing to return the requested Presto data quickly.
Configure Presto Connectivity for HeidiSQL
Connectivity to Presto from HeidiSQL is made possible through CData Connect Cloud. To work with Presto data from HeidiSQL, we start by creating and configuring a Presto connection.
- Log into Connect Cloud, click Connections and click Add Connection
- Select "Presto" from the Add Connection panel
-
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
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.
- Click on your username at the top right of the Connect Cloud app and click User Profile.
- On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
- Give your 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.
Connect to Presto from HeidiSQL using Connect Cloud
To establish a connection from HeidiSQL to the CData Connect Cloud Virtual SQL Server API, follow these steps.
Create a new HeidiSQL Session
- In the Session Manager, select New in the bottom-left
- Give the new session a descriptive name, e.g. Connect-Cloud-Presto
Configure a SQL Server Connection to Connect Cloud
- In the session settings, set the Network type to Microsoft SQL Server (TCP/IP)
- The Library DLL should automatically update to MSOLEDBSQL
- Set the Hostname/IP to tds.cdata.com
- Set the User to your CData Connect Cloud username. This is displayed in the top-right corner of the CData Connect Cloud interface. For example, [email protected]
- Set the Password to your PAT created in Connect Cloud in the previous section.
- Set the Port to 14333
Query Presto from HeidiSQL
- In the database listing on the left, find your connection to Presto configured earlier.
- Expand this connection to view individual tables or data objects present within Presto.
- Write custom SQL queries targeting these tables, treating the data source like any SQL Server database, or visually explore each tabular data set by selecting the relevant tables
