**Description:**
We need to create 2 new streams to validate events generated by the session tick mixin and click tracking. We can use the existing [[ https://gitlab.wikimedia.org/repos/data-engineering/schemas-event-secondary/-/tree/master/jsonschema/analytics/product_metrics/web/base?ref_type=heads | product web base schema ]], which has the right data shape for what we need.
This is instructions on how to configure a new stream.
https://wikitech.wikimedia.org/wiki/Metrics_Platform/Stream_configuration
The new streams will be called:
`'product_metrics.web_base.search_ab_test_session_ticks',`
`'product_metrics.web_base.search_ab_test_clicks',`
**User Story**
As an engineer working on event instrumentation, I need a well-defined schema and stream to validate session tick mixin events, so that event data is reliable and adheres to expected standards.
**Requirements**
This stream has the right shape for all the ab test click and session tick events
- after the stream is configured it should show up in Hive
**Acceptance Criteria**
Stream is configured and validated .
**Communication Criteria**
**Rollback Plan**
If issues arise, revert instrumentation changes to the previous state, and disable schema validation temporarily until resolved.
