Apache Spark Optimization Myth: Spark Dynamic Allocation

This white paper examines the limitations of Spark's Dynamic Allocation feature and why it isn't a complete solution for optimizing Apache Spark applications. Key points include:

Spark Dynamic Allocation can't prevent low resource utilization inside executors, leading to waste.
Dynamic Allocation can't ensure fair resource allocation in multi-tenant environments, where resource-hungry applications could starve others.
While Dynamic Allocation offers benefits, it can't solve the issue of Spark applications underutilizing resources, especially during non-peak times.

The paper debunks myths around observability, autoscaling, rightsizing, and manual tuning.
