The feature that I've found most valuable is the replay. That is one of the most valuable in our business. We are business-to-business so replay was an important feature - being able to replay for 24 hours. That's an important feature.
Amazon Kinesis offers high scalability for data streaming, handling large volumes with low latency, perfect for sizable environments. The replay feature and Lambda integration support business needs and real-time processing. Easy setup and robust documentation aid onboarding, though setup complexity requires familiarity. Limitations include a 10 MB file cap and high costs for large data volumes. Integrating features like Amazon Pinpoint enhances functionality, but data processing challenges impact stability. Enhanced pricing could boost competitiveness.
