Are your SQL queries running slow or consuming excessive resources? As data grows in size and complexity, writing optimized SQL queries becomes more crucial than ever. Knowing the right techniques can make all the difference.

In my latest blog, I explore best practices for writing efficient SQL queries, including:
Caching frequently accessed data
Minimizing data scans with precise filtering
Leveraging Liquid Clustering to handle skewed data dynamically
Optimizing joins for reduced shuffle costs
Efficient aggregation techniques to save memory
Each tip is paired with actionable SQL code examples, ensuring you can apply them directly to your projects. 💡

Let’s make data processing faster, smarter, and more cost-effective! 🚀
