------------------------------------
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.
