Glue cost analysis

AWS Glue costs are calculated based on the Data Processing Units (DPUs) used and the duration of your job runs. Here's how the pricing works for G.1X and G.2X worker types:

For G.1X workers:

• Each G.1X worker equals 1 DPU
• 4 vCPUs and 16 GB of memory per worker

For G.2X workers:

• Each G.2X worker equals 2 DPUs
• 8 vCPUs and 32 GB of memory per worker

AWS Glue charges an hourly rate of $0.44 per DPU-hour, billed by the second. There's a minimum billing duration of 1 minute for each job run, and after that, you're charged per second.

Sample cost analysis:

Example 1: G.1X with 2 workers running for 10 minutes

• 2 workers × 1 DPU per worker = 2 DPUs
• 10 minutes = 0.17 hours
• 2 DPUs × 0.17 hours × $0.44 per DPU-hour = $0.15 per job run

Example 2: G.2X with 2 workers running for 10 minutes

• 2 workers × 2 DPUs per worker = 4 DPUs
• 10 minutes = 0.17 hours
• 4 DPUs × 0.17 hours × $0.44 per DPU-hour = $0.30 per job run

If you're using AWS Glue Studio for development, note that interactive sessions (used for data preview) are also billed at the same DPU-hour rate. For example, a typical interactive session with 5 DPUs running for 24 minutes would cost: 5 DPUs × (24/60) hours × $0.44 per DPU-hour = $0.88.

To monitor your actual costs, you can use AWS Cost Explorer and filter for Glue services and specific usage types like "ETL-DPU-Hour" for your region.
