💡 This verdict is based on general use cases. Your specific requirements, existing tech stack, and team expertise should guide your final decision.
Frequently Asked Questions
Does Beam run on Spark?
Yes, Beam has a Spark runner that executes Beam pipelines on Spark clusters. However, using Spark directly gives you access to Spark-specific optimizations that Beam's abstraction layer may not expose.
Is Beam slower than Spark?
Beam's abstraction layer can add overhead compared to using Spark directly. The performance difference varies by workload but is typically 5-15% for most pipelines.
Should I use Beam or Spark for Google Cloud?
Use Beam for Google Cloud Dataflow (it's the native SDK). Use Spark for Databricks on GCP or Dataproc. Both work well on Google Cloud.
