             Summary: Restart failed tasks in Kafka Connect up to a 
configurable max-tries
                 Key: KAFKA-15408
                 URL: https://issues.apache.org/jira/browse/KAFKA-15408
             Project: Kafka
          Issue Type: New Feature
          Components: KafkaConnect
            Reporter: Patrick Pang


h2. Issue

Currently, Kafka Connect just reports failed tasks on REST API, with the error. 
Users are expected to monitor the status and restart individual connectors if 
there is transient errors. Unfortunately these are common for database 
connectors, e.g. transient connection error, flip of DNS, database downtime, 
etc. Kafka Connect silently failing due to these scenarios would lead to stale 
data downstream.
h2. Proposal

Kafka Connect should be able to restart failed tasks automatically, up to a 
configurable max-tries.
