Introduction

JSON / REST API is becoming more and more popular each day as everyone embrace cloud-centric services. This article is primarily focused on Informatica users who want to access Starburst data or may be other API Integration in Informatica. However many tips and techniques described in this article will help you to understand how to integrate Starburst / XML SOAP / JSON / REST API in other ETL / Reporting apps such as Tableau, Power BI, SSRS, Talend, Excel and many more.

After going through this article you will learn how to Read Starburst / JSON / REST API data in Informatica and understand the concept of JSON / REST API. We will go through many screenshots and step-by-step examples to demonstrate  Starburst or REST API integration in Informatica PowerCenter.

XML / JSON can come from a local file or REST API service (internal or public) so we will include both examples in this article (i.e. Read JSON files in Informatica,  Import REST API in Informatica). So let’s get started. Next article will focus on how to write data to API in Informatica (POST / PUT data)

Requirements

This article assumes that you have full filled following basic requirements.

1. Download Install ZappySys ODBC PowerPack (API Driver for Starburst included)
2. Install Informatica PowerCenter Client Tools (e.g. Workflow and Mapping Designers)
3. Access to a Relational database such as SQL Server (or use any of your choice e.g. Oracle, MySQL, DB2 ). If nothing available then you can use flat file target.

High level Steps for Import Starburst data using Informatica (Read Starburst API data)

Before we dive deep to learn how to load Starburst data in Informatica (i.e. Starburst to SQL Table), Here the summary of high-level steps you need to perform to import Starburst in Informatica (same steps for Import JSON / XML / REST API).

1. Download and Install ZappySys API Driver (for connecting to Starburst)
2. Create ODBC DSN using ZappySys API driver and choose Starburst Connector during Wizard
3. Create Relational > ODBC Connection in Informatica Workflow designer (Point to DSN we created in the previous step)
4. Import Starburst Source Definition in the Informatica Mapping Designer > Sources Tab
5. Import Target Table Definition in the Informatica Mapping Designer > Targets Tab
6. Create source to target mapping in Mappings tab
7. Save mapping (name m_API_to_SQL_Load )
8. Create Session using the mapping we created in the previous step
9. Save Workflow and execute to load Starburst data into SQL Table. Verify your data and log.

Getting Started – Import Starburst to SQL Server in Informatica

Now let’s get started. For example purpose, we will read data from Starburst and load data into SQL Server Table using Informatica Workflow.

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

Step-by-step instructions

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

1. Download and install ODBC PowerPack.

2. Open ODBC Data Sources (x64):

   

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

   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.

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

   ****************

   []

   

   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:

   

   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

   

   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.

Create Connection in Informatica Workflow Designer

Once you create DSN using API Driver our next step is to define a connection for Starburst source in Informatica PowerCenter Workflow designer.

1. Open Workflow designer [W] icon
2. Goto Connections > Relational
   

   Create a new connection for Starburst in Informatica

3. Click New and select ODBC
   

   Select ODBC connection type in Informatica (Using ZappySys API ODBC DSN)

4. Now on the ODBC connection setup enter connection name, some fake userid / password (this is a required field but its ignored by JSON Driver)
5. In the Connection String field enter the exact same name of DSN (Open ODBC Data Sources UI to confirm)
   

   Configure Starburst connection in Informatica for REST API – Using ZappySys API Driver

6. Click OK to close the connection properties.

That’s it. Now we ready to move to next step (define source and target in Mapping Designer).

Import Starburst Source Definition in Informatica Mapping Designer

Now let’s look at steps to import Starburst table definition.

1. Open Informatica Mapping Designer (Click [D] icon)
2. Click on Source Icon to switch to Sources designer
3. From the top menu > Click on Sources > Import from Database …
   

   Import Starburst Source definition in Informatica Mapping Designer (JSON file or REST API)

4. Select ODBC data source from the dropdown (Find out DSN we created earlier to use as JSON Source)
5. Click Connect button to get a list of tables. Any array node is listed as a table. Also, you will see array node with parent columns (e.g. value_with_parent). You may get some warning like below but they are harmless so just ignore by clicking OK.

8. That’s it, we are now ready to perform similar steps to import Target table structure in the next section.

Import SQL Server Target Definition in Informatica Mapping Designer

Now let’s look at steps to import Target table definition (very similar to the previous section, the only difference is this time we will select DSN which points to SQL Server or any other Target Server).

Now lets look at steps to import target table definition in Informatica mapping designer.

1. In the Mapping Designer, Click on Target Icon to switch to Target designer
2. From the top menu > Click on Targets > Import from Database …
3. Select DSN for your Target server (if DSN doesn’t exist then create one by opening ODBC Sources just like we created one for JSON API source (see the previous section about creating DSN).
   

   Import target Table Definition in informatica

4. Enter your userid , password and Schema name and click Connect to see tables
5. Select Table name to and click OK import definition.
   

   Import Target SQL Table Definition in Informatica – Select table from the list

Create Source to Target Mapping in Informatica (Import JSON to SQL Server)

Once you have imported source and target table definition, we can create mapping and transformation to load data from JSON to SQL Table.

1. First open Mapping Designer (Click [D] icon)
2. Drag JSON Source from sources folder
3. Drag SQL Table from Targets folder
4. Map desired columns from Source to target
   

   Define Source to Target mapping for Starburst to SQL Table load in Informatica

5. For certain columns you may have to do datatype conversion. For example to convert OrderDate form nstring to DataTime you have to use Expression Transform like below and map it to target. In below example, our JSON has date format (e.g. 2018-01-31 12:00:00 AM ). To import this to DateTime field in SQL server we need to convert it using TO_DATE function. Use double quotes around T to make this format working.
   

   TO_DATE(OrderDate,'YYYY-MM-DD H12:MI:SS AM')
   
    --For ISO use below way
           TO_DATE(OrderDate,'YYYY-MM-DD"T"HH24:MI:SS')

6. Once you done with mapping save your mapping and name it (i.e. m_Api_To_SQL)
7. Now lets move to next section to create workflow.

Create Workflow and Session in Informatica

Now the final step is to create a new workflow. Perform following steps to create workflow which with a session task to import JSON data into SQL table.

1. Open workflow designer by click [W] icon.
2. Launch new workflow creation wizard by click Workflow top menu >  Wizard
   name your workflow (e.g. wf_Api_Tp_Sql_Table_Import)
