Interesting post from Rajat Rana on Meesho's technology blog. Meesho is a huge Indian e-commerce platform. He shares how, and why, they rebuilt their real-time analytics platform on Apache Pinot to support a wider variety of sophisticated features — such as identity merging, deep insights, funnel analysis, and complex user journeys.

(I work at StarTree - a real-time analytics platform powered by Pinot - we helped them implement this)
