Analysing high throughput Data in Real Time

Data Engineering at Hotstar
At Hotstar, India’s largest premium streaming and entertainment platform, we generate more than 15 Billion clickstream events per day. This data is generated from multiple sources and by multiple teams. We built Bifrost, our internal Data Management Platform, as a single platform that allows users to ingest data of any kind & shape, and allow users to query the streaming and stationary data with ease. The data ingestion API abstracts the underlying complexities of producing, consuming, and processing data. It is built to be highly available, durable and resilient since this is the single entry point for all data coming into Hotstar
Kafka is the backbone of our real-time data platform, data is ingested through the in-house fault tolerant solutions around the ingestion API layer which is written entirely in Go to reliably ingest TBs of validated data each day at a peak of a Million messages per second.
In this presentation we will discuss the promises and use of Stream processing over Kafka Streams leveraging KSQL to analyse the ingested events to solve certain real-time use cases such as Playback Failure Rate which is a fundamental metric for over the top media streaming platforms.

Speaker bio
Currently, Data Engineering at Hotstar. Previously at WebEngage and co-founder at CareODrive. Interested in spreading/sharing knowledge and in solving problems at a scale that matters. Previously held talks at Golang Meet-Ups, Bangalore, India and the 21CF Global Data Summit. Big fan of Radiohead, hit me up for a jam session any time.
