Comprehensive analysis of AWS Glue's strengths and weaknesses based on real user feedback and expert evaluation.
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
7 major strengths make AWS Glue stand out in the deployment & hosting category.
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
7 areas for improvement that potential users should consider.
