This means offsets are committed periodically regardless of whether the data was successfully processed and stored in the database. If the database insertion fails (e.g., due to a constraint violation or connection loss), the message is considered "consumed" by Kafka, leading to data loss. + +Additionally, if the PostgreSQL database goes offline, the consumer continues to try processing messages, likely filling logs with errors and potentially losing data if retries aren't handled correctly. The user requires a mechanism to pause consumption during DB outages and resume only when the DB is back online. + +## Proposal + +We propose to enhance the reliability of the ingestion pipeline by: + +1. **Disabling Auto-Commit**: + - Set `autoCommit: false` in the Kafka `ConsumerGroup` configuration. + - Implement manual offset committing only after the database insertion is confirmed successful. + +2. **Implementing DB Offline Handling (Circuit Breaker)**: + - Detect database connection errors during insertion. + - If a connection error occurs: + 1.
