About this tool
Event Schema Validator
The Event Schema Validator checks event payloads for required fields, UUID event_id, ISO 8601 timestamps, schema_version, and CloudEvents spec compatibility.
• Validate event schema before publishing to a Kafka topic
• Check whether an event payload has all fields needed for deduplication
• Verify ISO 8601 timestamp format before a data pipeline implementation
• Assess CloudEvents compliance before adopting the standard

FAQ
What does this tool tell you?
The Event Schema Validator checks event payloads for required fields, UUID event_id, ISO 8601 timestamps, schema_version, and CloudEvents spec compatibility.
What affects the result most?
Event schema required fields: event_id (UUID), event_type, occurred_at (ISO 8601), schema_version. Event ID: UUID v4 for deduplication — idempotent consumers need this. occurred_at vs ingested_at: event time vs processing time — always capture both.
How should I use the result?
Treat the tool's output as a first-pass check, not a proof of correctness. A clean pass means no issues in the patterns this tool recognizes; a failure points to a specific problem you can investigate in your source. The underlying spec is the authoritative source for edge cases.
