• Subscriptions at Hotstar
• Scaling read path for Subscriptions - Worked on requirement for always serving subscriptions via cache for Get Subs API. Earlier store used to serve around 1% of the calls with DB, this was a bottleneck for scaling the read path aggressively. Worked on coherent integration of cache/disk in the write flow as to always retrieve subscriptions via cache while maintaining near-atomic consistency. Also worked on fine-tuning failures/timeouts at the caching layer. This helped us scale to 50M platform concurrency - 25% of this traffic roughly translates to subscription layer.
• Worked on resiliency aspects for subscription service such as writing circuit breakers for degradation scenarios, individual pod testing, stress testing, (nested) query optimisations and tuning connection factory settings for cache/db control for live sporting events like Cricket World cup 2023.
• Worked on load test/performance-measure for entire subscription ecosystem and ensured there are no bottlenecks/issues for the big live sporting events like Asia cup 2022 and T20 World cup 2022.
• Worked on design and development of free trial (& fraud detection) MVP for Disney+ Hotstar - a feature that lets new users enjoy entitlements for a short period without subscribing - with a fraud detection layer around it over multiples dimensions like device-id and phone to avoid abuse.
• Worked on the initial design for consumption only flow for Disney+ Hotstar that lets user purchase entitlements on mweb/web (thereby passing payments on the app due to compliance reasons) so that the app remains only available for content consumption. This is targeted for high tier users and is in experimental phase.
