NOTE: This task captures all of the outputs under the Q1 Product Analytics Infrastructure sub-program of {T225237}.
## Definitions
- ** Event** - A JSON data object, conforming to some JSONSchema, usually representing something happening at a definite time Event Platform Client Libraries
- **Event Platform** - EventGateEach of our product platforms has an existing library used to detect data in the form of events, and send these events to our [[ https://wikitech.wikimedia.org/wiki/Event_Platform | event platform ]].
- We want to avoid a situation where data from different products cannot be compared due to differences in the way that the data was collected.
- It is impossible to use a single implementation to cover all products.
In order to solve this engineering challenge, we will create a **common specification** for all "event platform clients" to follow. We will then implement the specification, section-by-section, the Stream Configuration Service,on each of these existing libraries until they are brought into conformance. Schema RegistryOnce this is done, Kafkathe specification will serve as a foundation for documentation of the system, and Hadoop,a technical structure on which to build and organize analytics practices across the product organization. etc.In particular, See [[it will provide a guide to re-factoring and upgrading libraries to produce events to [[ https://wikitech.wikimedia.org/wiki/Event_Platform/EventGate | EventGate ]] rather than [[ https://wikitech.wikimedia.org/wiki/Analytics/Systems/Event_PlatformLogging | Event Platform]].Logging ]].
### Specification
- **Event Platform Client** - Any software wishing to send events to the Event Platform.The specification is organized into sections, each covering a functional unit of software. These are:
- {T230578} - buffering events or HTTP requests
- **Event Platform Client Library** - The software allowing an Event Platform Client to send events to the Event Platform
