fix: use segments from kafka instead of fivetran [CM-1082]

[mbani01]

This pull request updates the segment resolution logic in several Snowflake connector integrations to use the ANALYTICS.BRONZE_KAFKA_CROWD_DEV.SEGMENTS table instead of the previous ANALYTICS.SILVER_DIM._CROWD_DEV_SEGMENTS_UNION table. This change is applied consistently across multiple modules and their associated queries, ensuring that all segment lookups reference the correct and up-to-date source.

Segment resolution source update:

• Updated all references in comments and queries from ANALYTICS.SILVER_DIM._CROWD_DEV_SEGMENTS_UNION to ANALYTICS.BRONZE_KAFKA_CROWD_DEV.SEGMENTS for segment resolution in the following modules:
  • cvent/event-registrations/buildSourceQuery.ts [1] [2]
  • tnc/certificates/buildSourceQuery.ts [1] [2] [3]
  • tnc/courses/buildSourceQuery.ts [1] [2]
  • tnc/enrollments/buildSourceQuery.ts [1] [2] [3]

Note

Medium Risk
Moderate risk because it changes the Snowflake table used for segment resolution across multiple exports, which can alter which records are included or excluded if schemas/data differ.

Overview
Switches segment resolution in Snowflake connector source queries to use ANALYTICS.BRONZE_KAFKA_CROWD_DEV.SEGMENTS instead of ANALYTICS.SILVER_DIM._CROWD_DEV_SEGMENTS_UNION.

This update is applied consistently to both the main cdp_matched_segments CTE and the incremental new_cdp_segments logic in the Cvent event registrations and TNC certificates/courses/enrollments connectors, plus related inline documentation.

Pull request overview

This PR updates Snowflake connector segment-resolution CTEs to read from the Kafka-derived ANALYTICS.BRONZE_KAFKA_CROWD_DEV.SEGMENTS table instead of the legacy ANALYTICS.SILVER_DIM._CROWD_DEV_SEGMENTS_UNION source, aligning segment lookups across the affected integrations.

Changes:

• Switched cdp_matched_segments and new_cdp_segments CTEs to select segments from ANALYTICS.BRONZE_KAFKA_CROWD_DEV.SEGMENTS.
• Updated inline module join documentation comments (where present) to reference the new segments table.
