iOS Telemetry Pipeline with Kinesis, Glue, and Athena
Any iOS app with real users generates telemetry. Session starts, feature usage, error events, performance metrics, purchase funnels. Most teams start by shipping all of it to Amplitude or Mixpanel and calling it done. That works for a while. Then the monthly invoice triples, you discover the vendor's data model cannot answer a question your PM asked three days ago, and you realize you are paying somebody else to store your data in a format optimized for their business.
