Amazon Athena Connector for Talend Studio

Amazon Athena Connector allows to connect to serverless, interactive analytics service that provides a simplified and flexible way to analyze petabytes of data where it lives.

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

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

Download Documentation

Amazon Athena Connector for Talend Studio is based on ZappySys JDBC Bridge Driver which is part of ODBC PowerPack. It is a collection of high-performance ODBC drivers that enable you to integrate data in SQL Server, SSIS, a programming language, or any other ODBC-compatible application. ODBC PowerPack supports various file formats, sources and destinations, including REST/SOAP API, SFTP/FTP, storage services, and plain files, to mention a few.

Prerequisites

Before we begin, make sure you meet the following prerequisite: Java Runtime Environment (JRE) or Java Development Kit (JDK) must be installed on your system.

Minimum required version: Java 8
- Amazon Corretto 8
- Oracle JRE 8
Recommended Java version: Java 21
- Amazon Corretto 21
- Oracle JRE 21

If your JDBC Driver targets a different Java version (e.g., 11 / 17 / 21), install the corresponding or newer Java version.

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 Amazon Athena JDBC driver

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

Visit Amazon Athena official website.
Download the JDBC driver, and save it locally, e.g. to D:\Drivers\JDBC\athena-jdbc.jar.
Done! That was easy, wasn't it? Let's proceed to the next step.

Create Data Source in Data Gateway based on ZappySys JDBC Bridge Driver

In this section we will create a data source for Amazon Athena in Data Gateway. Let's follow these steps to accomplish that:

Download and install ODBC PowerPack.
Search for gateway in Windows Start Menu and open ZappySys Data Gateway Configuration:
Go to Users tab and follow these steps to add a Data Gateway user:
- Click Add button
- In Login field enter username, e.g., john
- Then enter a Password
- Check Is Administrator checkbox
- Click OK to save
Now we are ready to add a data source:
- Click Add button
- Give Datasource a name (have it handy for later)
- Then select Native - ZappySys JDBC Bridge Driver
- Finally, click OK
AmazonAthenaDSN

ZappySys JDBC Bridge Driver
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:

AmazonAthenaDSN

jdbc:athena://WorkGroup=primary;Region=us-east-1;Catalog=MyAwsDataCatalog;OutputLocation=s3://my-s3-bucket/;

com.amazon.athena.jdbc.AthenaDriver

D:\Drivers\JDBC\athena-jdbc.jar

AKIAIOSFODNN7EXAMPLE

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

[]

Use these values when setting parameters:
- Connection string: jdbc:athena://WorkGroup=primary;Region=us-east-1;Catalog=MyAwsDataCatalog;OutputLocation=s3://my-s3-bucket/;
- Driver class: com.amazon.athena.jdbc.AthenaDriver
- JDBC driver file(s): D:\Drivers\JDBC\athena-jdbc.jar
- User name: AKIAIOSFODNN7EXAMPLE
- User password: ******************************
- Connection parameters: []
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.
We are at the point where we can preview a SQL query. For more SQL query examples visit JDBC Bridge documentation:
AmazonAthenaDSN
```
SELECT * FROM "r53_rlogs"
ORDER BY query_timestamp DESC
```
```
SELECT * FROM "r53_rlogs"
ORDER BY query_timestamp DESC
```
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 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.
Click OK to finish creating the data source.
Very important step. Now, after creating or modifying the data source make sure you:
- Click the Save button to persist your changes.
- Hit Yes, once asked if you want to restart the Data Gateway service.
This will ensure all changes are properly applied:

Skipping this step may result in the new settings not taking effect and, therefore you will not be able to connect to the data source.

Read Amazon Athena data in Talend Studio

To read Amazon Athena data in Talend Studio, we'll need to complete several steps. Let's get through them all right away!

This article is compatible with Talend Open Studio (a free version, currently retired by Qlik). If you don't have it, you can still purchase a shareware version of Talend Studio from Qlik.

Create connection for input

First of all, open Talend Studio
Create a new connection:
Select Microsoft SQL Server connection:
Name your connection:
Fill-in connection parameters and then click Test connection:

AmazonAthenaDSN
If the List of modules not installed for this operation window shows up, then download and install all of them:
Review and accept all additional module license agreements during the process
Finally, you should see a successful connection test result at the end:

Add input

Once we have a connection to ZappySys Data Gateway created, we can proceed by creating a job:
Simply drag and drop ZappySys Data Gateway connection onto the job:
Then create an input based on ZappySys Data Gateway connection:
Continue by configuring a SQL query and click Guess schema button:
Finish by configuring the schema, for example:

Add output

We are ready to add an output. From Palette drag and drop a tFileOutputDelimited output and connect it to the input:

Connecting tFileOutputDelimited output in Talend Studio

Run the job

Finally, run the job and integrate your Amazon Athena data:
