Starburst Connector for Power BI

Starburst Connector empowers you to connect to your Starburst Trino instance, the fastest open source, massively parallel processing SQL query engine designed for analytics on your data lake, as well as other data sources.

In this article you will learn how to quickly and efficiently integrate Starburst data in Power BI without coding. We will use high-performance Starburst Connector to easily connect to Starburst and then access the data inside Power BI.

Let's follow the steps below to see how we can accomplish that!

Video Tutorial - Integrate Starburst data in Power BI

This video covers the following topics and more, so please watch carefully. After watching the video, follow the steps outlined in this article:

  • How to download and install the required PowerPack for Starburst integration in Power BI
  • How to configure the connection for Starburst
  • Features of the ZappySys JDBC Bridge Driver (Authentication / Query Language / Examples / Driver UI)
  • How to use the Starburst in Power BI

Prerequisites

Before we begin, make sure you meet the following prerequisite:

If you already have a JRE installed, you can try using it too. However, if you experience any issues, we recommend using one of the distributions mentioned above (you can install an additional JRE next to the existing one; just don't forget to configure the default Java in the Windows Environment Variables).

Download Starburst JDBC driver

To connect to Starburst in Power BI, you will have to download JDBC driver for it, which we will use in later steps. Let's perform these little steps right away:

  1. Visit Starburst website.
  2. Follow the instructions there, download the JDBC driver, and save it locally, e.g. to D:\Drivers\JDBC\trino-jdbc.jar.
    It is recommended to use JDBC driver compiled for Java 8, if possible.
  3. Done! That was easy, wasn't it? Let's proceed to the next step.

Create ODBC Data Source (DSN) based on ZappySys JDBC Bridge Driver

Step-by-step instructions

To get data from Starburst using Power BI we first need to create a DSN (Data Source) which will access data from Starburst. We will later be able to read data using Power BI. Perform these steps:

  1. Download and install ODBC PowerPack.

  2. Open ODBC Data Sources (x64):

    Open ODBC Data Source
  3. Create a User data source (User DSN) based on ZappySys JDBC Bridge Driver

    ZappySys JDBC Bridge Driver
    Create new User DSN for ZappySys JDBC Bridge Driver
    • Create and use User DSN if the client application is run under a User Account. This is an ideal option in design-time, when developing a solution, e.g. in Visual Studio 2019. Use it for both type of applications - 64-bit and 32-bit.
    • Create and use System DSN if the client application is launched under a System Account, e.g. as a Windows Service. Usually, this is an ideal option to use in a production environment. Use ODBC Data Source Administrator (32-bit), instead of 64-bit version, if Windows Service is a 32-bit application.
    Power BI uses a Service Account, when a solution is deployed to production environment, therefore for production environment you have to create and use a System DSN.
  4. Now, we need to configure the JDBC connection in the new ODBC data source. Simply enter the Connection string, credentials, configure other settings, and then click Test Connection button to test the connection:

    StarburstDSN
    jdbc:trino://trino-instance-host-name:8080
    D:\Drivers\JDBC\trino-jdbc.jar
    admin
    ****************
    []
    JDBC-ODBC Bridge driver data source settings

    Use these values when setting parameters:

    • Connection string: jdbc:trino://trino-instance-host-name:8080
    • JDBC driver file(s): D:\Drivers\JDBC\trino-jdbc.jar
    • User name: admin
    • User password: ****************
    • Connection parameters: []

  5. You should see a message saying that connection test is successful:

    ODBC connection test is successful

    Otherwise, if you are getting an error, check out our Community for troubleshooting tips.

  6. We are at the point where we can preview a SQL query. For more SQL query examples visit JDBC Bridge documentation:

    StarburstDSN
    SELECT * FROM tpch.sf1.orders
    JDBC ODBC Bridge data source preview
    SELECT * FROM tpch.sf1.orders
    You can also click on the <Select Table> dropdown and select a table from the list.

    The ZappySys JDBC Bridge Driver acts as a transparent intermediary, passing SQL queries directly to the Trino JDBC driver, which then handles the query execution. This means the Bridge Driver simply relays the SQL query without altering it.

    Some JDBC drivers don't support INSERT/UPDATE/DELETE statements, so you may get an error saying "action is not supported" or a similar one. Please, be aware, this is not the limitation of ZappySys JDBC Bridge Driver, but is a limitation of the specific JDBC driver you are using.

  7. Click OK to finish creating the data source.

Read Starburst data in Power BI using ODBC

Importing Starburst data into Power BI from table or view

  1. Once you open Power BI Desktop click Get Data to get data from ODBC:
    Power Bi Get Data

  2. A window opens, and then search for "odbc" to get data from ODBC data source:
    Power Bi ODBC Get Data

  3. Another window opens and asks to select a Data Source we already created. Choose StarburstDSN and continue:

    StarburstDSN
    Power Bi Select ZappySys Driver DSN

  4. Most likely, you will be asked to authenticate to a newly created DSN. Just select Windows authentication option together with Use my current credentials option:

    StarburstDSN
    Power Bi DSN Authentication

  5. Finally, you will be asked to select a table or view to get data from. Select one and load the data!
    Power Bi Load DSN Table Data

  6. Finally, finally, use extracted data from Starburst in a Power BI report:
    Power Bi Extracted DSN Table Data

Importing Starburst data into Power BI using SQL query

If you wish to import Starburst data from SQL query rather than a table then you can use advanced options during import steps (as below). After selecting DSN you can click on advanced options to see SQL Query editor.

StarburstDSN
SELECT * FROM tpch.sf1.orders
Get REST API data in Power BI Desktop using SQL query and ODBC
Consider using Custom Objects feature in ODBC data source to encapsulate SQL query in a Virtual Table. This way, you can see a virtual table in Power BI table list where you can import multiple objects using the same connection rather than creating a new connection for each custom SQL query.

Using a full ODBC connection string

In the previous steps we used a very short format of ODBC connection string - a DSN. Yet sometimes you don't want a dependency on an ODBC data source (and an extra step). In those times, you can define a full connection string and skip creating an ODBC data source entirely. Let's see below how to accomplish that in the below steps:

  1. Open ODBC data source configuration and click Copy settings:
    ZappySys JDBC Bridge Driver - Starburst
    Starburst Connector empowers you to connect to your Starburst Trino instance, the fastest open source, massively parallel processing SQL query engine designed for analytics on your data lake, as well as other data sources.
    StarburstDSN
    Copy connection string for ODBC application
  2. The window opens, telling us the connection string was successfully copied to the clipboard: Successful connection string copying for ODBC application
  3. Then just paste the connection string into your script:
    StarburstDSN
    DRIVER={ZappySys JDBC Bridge Driver};JdbcConnectionString='jdbc:trino://trino-instance-host-name:8080';ClassName='';DriverPath='D:\Drivers\JDBC\trino-jdbc.jar';UserName='admin';UserPassword='****************';ConnParams='[]'
    Use full connection string in Power BI Desktop to read API data
  4. You are good to go! The script will execute the same way as using a DSN.
The DSN defined in the Data source name (DSN) field will be ignored.

Have in mind that a full connection string has length limitations.

Proceed to the next step to find out the details.

Limitations of using a full connection string

Despite using a full ODBC connection string may be very convenient it comes with a limitation: it's length is limited to 1024 symbols (or sometimes more). It usually happens when API provider generates a very long Refresh Token when OAuth is at play. If you are using such a long ODBC connection string, you may get this error:

"Connection string exceeds maximum allowed length of 1024"

But there is a solution to this by storing the full connection string in a file. Follow the steps below to achieve this:

  1. Open your ODBC data source.
  2. Click Copy settings button to copy a full connection string (see the previous section on how to accomplish that).
  3. Then create a new file, let's say, in C:\temp\odbc-connection-string.txt.
  4. Continue by pasting the copied connection string into a newly created file and save it.
  5. Finally, the last step! Just construct a shorter ODBC connection string using this format:
    DRIVER={ZappySys JDBC Bridge Driver};SettingsFile=C:\temp\odbc-connection-string.txt
  6. Our troubles are over! Now you should be able to use this connection string in Power BI with no problems.
This feature requires ODBC PowerPack v1.9.0 or later.

Editing query for table in Power BI

There will be a time you need to change the initial query after importing data into Power BI. Don't worry, just right-click on your table and click Edit query menu item:

Edit query in Power BI to get REST API data
Refer to Power Query M reference for more information on how to use its advanced features in your queries.

Using parameters in Power BI (dynamic query)

In the real world, many values of your REST / SOAP API call may be coming from parameters. If that's the case for you can try to edit script manually as below. In below example its calling SQL Query with POST method and passing some parameters. Notice below where paraAPIKey is Power BI Parameter (string type). You can use parameters anywhere in your script just like the normal variable.

To use a parameter in Power BI report, follow these simple steps:

  1. Firstly, you need to Edit query of your table (see previous section)

  2. Then just create a new parameter by clicking Manage Parameters dropdown, click New Parameter option, and use it in the query:

    						
                                = Odbc.Query("dsn=StarburstDSN",
                                             "SELECT ProductID, ProductName, UnitPrice, UnitsInStock
                                              FROM Products
                                              WHERE UnitPrice > " & Text.From(MyParameter) & "
                                              ORDER BY UnitPrice")
                            
                    
    Use parameter in Power BI to get REST API data
    Refer to Power Query M reference for more information on how to use its advanced features in your queries.

Using DirectQuery Option rather than Import

So far we have seen how to Import Starburst data into Power BI, but what if you have too much data and you don't want to import but link it. Power BI Offers very useful feature for this scenario. It's called DirectQuery Option. In this section we will explore how to use DirectQuery along with ZappySys Drivers.

Out of the box ZappySys Drivers won't work in ODBC Connection Mode, so you have to use SQL Server Connection rather than ODBC if you wish to use Live data using DirectQuery option. See below step-by-step instructions to enable DirectQuery mode in Power BI for Starburst data.

Basically we will use ZappySys Data Gateway its part of ODBC PowerPack. We will then use Linked Server in SQL Server to Link API Service, then issue OPENROWSET queries from Power BI to SQL Server, and it will then call Starburst via ZappySys Data Gateway.

  1. First, create a data source in ZappySys Data Gateway and create a Linked Server based on it.
  2. Once SQL Server Linked Server is configured we are ready to issue a SQL query in Power BI.
  3. Click Get Data in Power BI, select SQL Server Database
  4. Enter your server name and any database name
  5. Select Mode as DirectQuery
  6. Click on Advanced and enter query like below (we are assuming you have created Starburst Data Source in Data Gateway and defined linked server - change the name below).
    SELECT * FROM OPENQUERY([LS_TO_STARBURST_IN_GATEWAY], 'SELECT * FROM tpch.sf1.orders')
    SELECT * FROM OPENQUERY([LS_TO_STARBURST_IN_GATEWAY], 'SELECT * FROM tpch.sf1.orders')
    DirectQuery option for Power BI (Read Starburst Data Example using SQL Server Linked Server and ZappySys Data Gateway)

  7. Click OK and Load data... That's it. Now your Starburst API data is linked rather than imported.

Publishing Power BI report to Power BI service

Here are the instructions on how to publish a Power BI report to Power BI service from Power BI Desktop application:

  1. First of all, go to Power BI Desktop, open a Power BI report, and click Publish button:

    Publish Power BI report to Power BI service
  2. Then select the Workspace you want to publish report to and hit Select button:

    Publish Power BI report to workspace
  3. Finally, if everything went right, you will see a window indicating success:

    Successful Power BI report publishing

    If you need to periodically refresh Power BI semantic model (dataset) to ensure data accuracy and up-to-dateness, you can accomplish that by using Microsoft On-premises data gateway. Proceed to the next section - Refreshing Power BI semantic model (dataset) using On-premises data gateway - and learn how to do that.

Refreshing Power BI semantic model (dataset) using On-premises data gateway

Power BI allows to refresh semantic models which are based on data sources that reside on-premises. This can be achieved using Microsoft On-premises data gateway. There are two types of On-premises gateways:

  • Standard Mode
  • Personal Mode

Standard Mode supports Power BI and other Microsoft Data Fabric services. It fits perfectly for Enterprise solutions as it installs as a Windows Service and also supports Direct Query feature.

Personal Mode, on the other hand, can be configured faster, but is designed more for home users (you cannot install it as a Windows Service and it does not support DirectQuery). You will find a detailed comparison in the link above.

We recommend to go with Personal Mode for a quick POC solution, but use Standard Mode in production environment.

Below you will find instructions on how to refresh semantic model using both types of gateways.

Refresh using On-premises data gateway (standard mode)

Here are the instructions on how to refresh a Power BI semantic model using On-premises data gateway (standard mode):

  1. Go to Power BI My workspace, hover your mouse cursor on your semantic model and click Settings:

    Configure Power BI semantic model settings
  2. If you see this view, it means you have to install On-premises data gateway (standard mode):

    On-premises data gateway is not installed
  3. Install On-premises data gateway (standard mode) and sign-in:

    signing in into on-premises data gateway standard
    Use the same email address you use when logging in into Power BI account.
  4. Register a new gateway (or migrate an existing one):

    registering or migrating on-premises data gateway standard
  5. If you are creating a new gateway, name your gateway, enter a Recovery key, and click Configure button:

    naming on-premises data gateway standard
  6. Now, let's get back to your semantic model settings in Power BI portal. Refresh the page and you should see your newly created gateway. Click arrow icon and then click on Add to gateway link:

    ODBC{"connectionstring":"dsn=StarburstDSN"}
    Using On-premises Data Gateway Standard for Power BI Semantic Model
  7. Once you do that, you will create a new gateway connection. Give it a name, set Authentication method, Privacy level, and click Create button:

    dsn=StarburstDSN
    Create new connection in Power BI On-premises data gateway
    In this example, we used the least restrictive Privacy level.

    If your connection uses a full connection string you may hit a length limitation when entering it into the field. To create the connection, you will need to shorten it manually. Check the section about the limitation of a full connection string on how to accomplish it.

    On-premises data gateway (personal mode) does not have this limitation.

  8. Proceed by choosing the newly created connection:

    ODBC{"connectionstring":"dsn=StarburstDSN"}
    Selecting gateway connection in Power BI semantic model
  9. Finally, you are at the final step where you can refresh the semantic model:

    Refreshing Power BI semantic model using On-premises Data Gateway

Refresh using On-premises data gateway (personal mode)

Here are the instructions on how to refresh a Power BI semantic model using On-premises data gateway (personal mode):

  1. Go to Power BI My workspace, hover your mouse cursor on your semantic model and click Settings:

    Configure Power BI semantic model settings
  2. If you see this view, it means you have to install On-premises data gateway (personal mode):

    On-premises data gateway is not installed
  3. Install On-premises data gateway (personal mode) and sign-in:

    Sign-in to On-premises data gateway personal
    Use the same email address you use when logging in into Power BI account.
  4. Again, go to your semantic model Settings, expand Data source credentials, click Edit credentials, select Authentication method together with Privacy level, and then click Sign in button:

    dsn=StarburstDSN
    Use On-premises data gateway personal for Power BI semantic model
  5. Finally, you are ready to refresh your semantic model:

    Refreshing Power BI semantic model using On-premises Data Gateway
