Load data from Amazon Athena

Download JDBC driver

Download the latest Amazon Athena JDBC driver from the Connect to Athena with JDBC page on the Amazon Athena website.

If you want to use JDBC 2.x, download the JDBC 2.x driver with AWS SDK.

Add JDBC driver

1. Create a configuration file settings.cfg with the following settings:

   Copy

   DRIVERNAME=Athena
   PREFIX=jdbc:awsathena:
   FETCHSIZE=100000
   INSERTSIZE=-1
   NOSECURITY=YES
   

   The file must end with an empty line (line break followed by zero characters).

2. Upload the settings.cfg file and the driver .jar file to BucketFS in the Exasol cluster.

   In Exasol 2025.1 and later you can upload files using Exasol Admin. You can also use any compatible file transfer tool, including curl on the command line. See also Manage files in BucketFS.

   In Exasol SaaS you must upload the driver through the web console.

   If the driver was downloaded as a .tar.gz or .zip archive, make sure that you extract and upload only the .jar file along with the settings.cfg file.

   Example (using curl in Linux):

   Copy

   export WRITE_PW=<your_bucketfs_write_password>
   export DATABASE_NODE_IP=<ip_address_of_cluster_node>
   export PORT=<bucketfs_port> # default: 2581
   
   curl -v --insecure -X PUT -T settings.cfg https://w:$WRITE_PW@$DATABASE_NODE_IP:$PORT/default/drivers/jdbc/exasol/settings.cfg
   curl -v --insecure -X PUT -T exajdbc.jar https://w:$WRITE_PW@$DATABASE_NODE_IP:$PORT/default/drivers/jdbc/exasol/exajdbc.jar

   The option --insecure or -k tells curl to bypass the TLS certificate check. This option allows you to connect to a HTTPS server that does not have a valid certificate. Only use this option if certificate verification is not possible and you trust the server.

Virtual schema

Exasol provides a virtual schema for connecting Amazon Athena as a data source to Exasol. For more information and downloads, see athena-virtual-schema in our GitHub repository.
