Principal/Senior-level Spark playbook for batch and streaming architecture, data layout, shuffle control, cost-efficient compute, reliability, and operating large-scale data processing platforms. Use when: designing Spark workloads, tuning jobs, optimizing cluster economics, or operating Spark platforms in production.

General

What this skill does


# Spark Mastery (Senior → Principal)

## Operate

- Start from data volume, compute economics, shuffle behavior, and correctness requirements.
- Treat Spark as a distributed execution system with real storage, network, and scheduling tradeoffs.
- Prefer explicit workload design over vague “big data” assumptions.
- Optimize for predictable cost, reliability, and debuggable pipelines.

## Default Standards

- Data layout and partitioning must match workload reality.
- Shuffle-heavy patterns require scrutiny.
- Memory and executor tuning should follow evidence.
- Streaming and batch semantics must be separated clearly.
- Platform cost and job performance should be evaluated together.
