Redshift Performance Tuning Nobody Teaches (Production Playbook)
Redshift performance issues rarely come from “bad SQL.”
They come from architecture, workload management, and production realities that most tutorials never mention.
In this episode, we break down how Redshift actually behaves under real workloads — and what you need to tune beyond simple query optimization.
We cover:
• Why sort keys matter more than indexes
• Distribution styles and data skew pitfalls
• WLM queues and concurrency contention
• Backfills that melt clusters
• VACUUM / ANALYZE tradeoffs
• Locking, queueing, and long-running queries
• When scaling up doesn’t actually fix the problem
• A practical production tuning playbook
This isn’t a beginner's guide.
It’s what you learn after running Redshift at scale in production.
If you’re building real data platforms — not toy demos — this episode is for you.
