Analytics in AWS Athena

Pre-requisites

A pre-requisite for running Athena analytics is configuring an S3 bucket for your Athena data. In this example we'll use a bucket called trelica-athena-results. 

Initializing Athena tables

Log in to your AWS account with the appropriate role using the aws sso login command.

Download run_athena_init.sh and init_athena_s3.sql:

aws s3 cp s3://<YOUR-BUCKET>/trelica/2025-10-22/run_athena_init.sh .
aws s3 cp s3://<YOUR-BUCKET>/trelica/2025-10-22/init_athena_s3.sql .

Athena only lets you run a single SQL statement at a time, so the run_athena_init.sh script will automate running the SQL file for you.

The parameters for run_athena_init.sh are:

• the Athena database name you want to create, 
• the S3 bucket for storing Athena results

./run_athena_init.sh trelica_snapshot s3://trelica-athena-results

Querying from AWS

Once this has completed, log in to Athena in the AWS Management Console.

Before running a query you will be prompted to specify the location for your query results (if you haven't already done so):

Click Browse S3 to pick a folder in one of your S3 buckets.

Now return to the query editor. Select the Database you created (in this case trelica_snapshot). You should see the Tables list populate and you can then run queries against those tables.
