DLQ behavior with errors.tolerance=none - records sent to DLQ despite "none" tolerance setting #1169
Description
When configuring the Snowflake Kafka Connector with:
errors.deadletterqueue.topic.name=my-connector-errors
errors.tolerance=none
tasks.max=10
My kafka topic had 5 partitions.
When sending an error record, I observe:
- 10 records appear in the DLQ topic (one per task)
- All tasks are in failed state
Is this current behavior intentional or a bug? Should errors.tolerance=none prevent DLQ usage entirely, or is the Snowflake connector designed to always use DLQ when configured?
- Connector version: 3.1.3
- Kafka Connect version: 3.9.0
