A Day in the Life of a Data Engineer
Me: “The data pipeline is running perfectly!” 😎
Airflow: ✅ DAG successful
SQL: ✅ Query executed
Dashboard: 📊 Looking good!
Business team: “Why are yesterday’s numbers different today?” 💀
Me: Opens 47 tabs, checks 12 SQL queries, and questions every data transformation ever written. 🤡
Finally, I find the issue…
Someone changed the source data format without telling anyone. 🥲
Data Engineering lesson: The data is never wrong. It’s just telling a story we haven't debugged yet. 😂
Data Engineers, what's your biggest nightmare?
Schema changes
Duplicate records
Failed DAGs at 2 AM
“Quick” SQL changes before a deadline ☕🤣
