Maintaining Data Pipelines' Sanity at Scale : How Validations and Metric Visualization came to our rescue!

Submitted Apr 15, 2019

Have you ever been through a nightmare when corrupt data from an upstream source led to a rogue index push to prod?

In this talk, I’ll walk through via case studies from our work at Flipkart :
1. Writing test cases for data pipelines. Validating datasets and generated patterns in addition to business logic.
2. Capturing and visualizating important metrics, and alerting. In-Lab and External recurring evaluation.
3. Brining Order to Chaos. Dealing With Staleness and Volume Drop.
