Snowflake Kafka Connector v3 Classic — Deprecation Timeline

Official Snowflake documentation page for the Kafka Connector v3 (Classic).

Deprecation timeline:

• Current status: Fully supported but planned for future deprecation.
• Formal deprecation announcement: Planned mid-2026.
• Migration window: 18 months following the announcement.
• Estimated end-of-life: Approximately late 2027.

Migration guidance:

• Snowflake recommends Kafka Connector v4 for all new implementations.
• A dedicated "Migrate from v3 to v4" resource is referenced (detailed steps in a separate migration document).
• No immediate changes required: existing v3 workloads are fully supported through the migration window.

Key message: "No immediate changes are required. Your current workloads are safe and continue to be fully supported."

Relationship to existing KG node: Complements source.docs-snowflake-com.en-user-guide-kafka-connector-overview-2026 (which covers the v3 architecture overview and already notes deprecation). This page provides the specific timeline and migration context. Together they ground TC-88 capability.streaming-ingestion body update on v3→v4 versioning.

Curriculum relevance (TC-88): Module 15 uses the Snowflake Kafka Connector for streaming ingestion. The curriculum should clarify v3 vs. v4 architecture differences; this source grounds the deprecation timeline claim.
