Study Notes
AWS Glue Executor Allocation
- The maximum number of allocated executors is shown as a horizontal red line on the graph, corresponding to the number of designated Data Processing Units (DPUs).
- In the scenario described, 10 DPUs are allocated for the job.
Job Metrics and Monitoring
- The AWS Glue console provides metrics on job performance, including executor allocation based on DPUs.
- To analyze job performance in detail, select a job run and choose ‘View run metrics’ in the Glue console.
DPU Capacity Assessment
- The Job Run Monitoring section allows users to assess the necessary DPU capacity by reviewing previous job runs.
- Analyzing past job runs provides insights into the optimal DPU allocation for future jobs.
Common Misconceptions
- Using Amazon CloudWatch Logs to review job logs for “DPU” is not suitable for optimizing DPU numbers, as it examines aggregate job details rather than specific capacity needs.
- The ETL section in the AWS Glue console offers only a high-level overview; it lacks the in-depth analysis required for optimizing DPU usage.
- Job bookmarks are not intended for tracking DPU consumption; they are designed to ensure jobs only process new or updated data by maintaining state information about previously processed data.
