Vibe Check: Can AI Actually Write Spark? Live Coding w/ Databricks & Snowflake

​AI coding tools promise to make everything faster. But how well do they actually handle something like Spark, where the code has to be correct, performant, and work at scale?

In this Vibe Check, Melanie is joined by Holden Karau, Principal OSS Software Engineer at Snowflake and Apache Spark PMC member, and Lisa Cao, Staff Developer Advocate at Databricks, to find out. We'll write some Spark code live using AI tooling, look at what comes back, and have an honest conversation about where these tools help, where they fall short, and what you still need to know yourself.

Holden literally wrote the book on Spark (High Performance Spark, Learning Spark). Lisa oversees open source developer relations across MLflow, Spark, Delta Lake, and more at Databricks. Between them, they've seen every way Spark code can go wrong. Now we'll see how AI coding tools handle it.

Come with questions, bring your setup, and get real answers live.
