AWS Glue - Pros & Cons
Pros
- ✓Fully serverless with no infrastructure to provision, patch, or scale manually
- ✓Deep native integration with the AWS ecosystem (S3, Redshift, Athena, Lake Formation)
- ✓Always-free Data Catalog tier lowers the barrier for metadata management
- ✓Glue 4.0 significantly improved cold start times (up to 2.7x faster) and performance
- ✓Supports both batch and streaming ETL in a single service
- ✓DataBrew enables non-technical users to participate in data preparation
- ✓Auto-scaling adjusts DPUs dynamically to match workload, reducing over-provisioning
Cons
- ✗Cold start latency for Spark jobs can reach several minutes, making it unsuitable for low-latency or interactive workloads
- ✗Debugging Spark-based jobs can be complex—error messages are often opaque and require Spark expertise
- ✗VPC networking configuration for accessing private data sources adds operational complexity
- ✗Per-DPU-hour pricing can become expensive for long-running or always-on pipelines compared to reserved EMR clusters
- ✗Limited language support—primarily PySpark and Scala, with Ray support still maturing
- ✗Job orchestration capabilities are basic compared to dedicated tools like Apache Airflow or Step Functions
- ✗Vendor lock-in to AWS; migrating Glue-dependent pipelines to another cloud requires significant rework
