What I Learned From Reading 50 Data Pipeline Postmortems
An analysis of 50 data pipeline postmortems reveals recurring failure patterns across major tech companies. Most of these failures are preventable at the design stage rather than during operations. The study highlights issues such as schema drift and load spikes that frequently lead to data loss or corruption.
- ▪Four common failure patterns were identified in the postmortems from companies like Uber and Netflix.
- ▪Schema drift was the most prevalent issue, occurring in 38% of incidents.
- ▪Many failures could have been avoided with better design practices rather than operational fixes.
