Mastering Data Profiling and Analysis in ETLChallenge: Migrating data from a legacy system to a new data warehouse revealed significant anomalies. Resolution :- Data Profiling and AnalysisConducted detailed manual data profiling to uncover issues like duplicates, null values, and incorrect data types. For example, I identified that 20% of customer records had inconsistent formatting. Created an insightful data quality dashboard using custom scripts and tools to visualize and track the resolution of anomalies. Benefit: By identifying and addressing these issues early, I ensured a smooth transition with accurate and reliable data, saving the company from potential data-driven decision errors and boosting operational efficiency. 🔍 Meticulous data profiling is the cornerstone of a successful ETL process. Ensuring data integrity from the start is what sets top-tier ETL QA engineers apart. #DataQuality #ETLTesting #DataProfiling

What to Do with a Broken ETL Pipeline? The simplest approach is often to just re-run the pipeline, and sometimes that works! However, the easiest way isn’t always the best way. Relying on reruns can lead to recurring failures down the road. Here’s my approach: 𝗮𝗹𝘄𝗮𝘆𝘀 𝗮𝗶𝗺 𝘁𝗼 𝗺𝗮𝗸𝗲 𝗰𝗵𝗮𝗻𝗴𝗲𝘀 𝘁𝗼 𝘁𝗵𝗲 𝗘𝗧𝗟 𝗽𝗿𝗼𝗰𝗲𝘀𝘀 𝗮𝗳𝘁𝗲𝗿 𝗮 𝗳𝗮𝗶𝗹𝘂𝗿𝗲. The logic is straightforward—if your ETL pipeline breaks, it will likely break again in the future unless something is altered. Steps to handle a broken ETL pipeline: 1️⃣ Check the error: Start by examining the error that was raised. If you’ve set up retries, look at the first attempt (original run) for clues. 2️⃣ Debug and resolve: Understand the root cause of the failure and update your code to ensure similar issues don’t arise again. This proactive change can prevent future disruptions. 3️⃣ Change the pipeline timing: If you can’t pinpoint the exact reason, consider adjusting the pipeline’s schedule. Sometimes, data sources undergo maintenance or other downtime that overlaps with your pipeline triggers. Personally, I get bad feeling when I saw the failure notification on my phone early in the morning, but it is a part of our job. Remember, even the best ETLs can fail. Not because data engineer missed something, but because the data provider changes something on its side, and they just didn’t mention it to you. 🔗Visit My Website: https://farnamdata.com/ #dataengineering #debug
