# org.apache.kafka.common.errors.TransactionTimeoutException: The transaction has timed out and has been aborted.

- **ID:** `kafka/transaction-aborted-due-to-timeout`
- **Domain:** kafka
- **Category:** runtime_error
- **Verification:** ai_generated
- **Fix Rate:** 82%

## Root Cause

A Kafka transactional producer exceeded `transaction.timeout.ms` before committing, causing the coordinator to abort the transaction.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| Kafka 2.5.0 | active | — | — |
| Kafka 3.1.0 | active | — | — |
| Kafka 3.5.0 | active | — | — |

## Workarounds

1. **Increase `transaction.timeout.ms` in the producer config (e.g., `transaction.timeout.ms=120000`) to accommodate longer-running transactions, and ensure the commit logic completes within this window.** (85% success)

2. **Optimize the transaction logic—e.g., reduce the number of partitions or messages per transaction, or use asynchronous commits where possible.** (75% success)

## Dead Ends

- **Setting `transaction.timeout.ms` to an extremely low value to speed up transactions** — A very low timeout increases the risk of aborts under normal load, making the system unstable. (80% fail)
- **Disabling idempotence to bypass transaction timeout checks** — Transactions require idempotence; disabling it will cause configuration errors and break transactional guarantees. (95% fail)
