Why This Question Matters

This easy-level Spark/Big Data question appears frequently in data engineering interviews at companies like Capco. While less common, it tests deeper understanding that distinguishes strong candidates. Mastering the underlying concepts (sql) will help you answer variations of this question confidently.

How to Approach This

Start by clearly defining the core concept being asked about. Interviewers want to see that you understand the fundamentals before diving into implementation details. Structure your answer with a definition, then explain the practical application with a concise example.

Glue Catalog: Serverless; AWS-managed. Integrates with Athena, EMR, Redshift. Pay per request. No infrastructure. Throttling at scale.

Hive Metastore: Self-managed (MySQL/Postgres). Full Hive compatibility. Control over config. Operational burden.

Why Choose: Glue for serverless-first, multi-service (Athena, EMR). Hive for heavy Hive workloads, portability, or cost at high request volume.

Scalability Trade-offs: Glue throttling (API limits); Hive scales with DB. Connection pooling for Hive.

Cost Implications: Glue: ~$1/million requests. Hive: EC2/RDS cost. At 100M requests/month, Hive may be cheaper.
