This table gives the ACLs required for the new API:
| RPC | Operation | Resource |
|---|---|---|
TxnHeartbeat | WRITE | Transactional ID |
InitProducerId API
The KIP introduces version 7 (or version 6 if this KIP is adopted before KIP-939's APIs are marked as stable).
...
The following configuration property is added for producers.
| Configuration | Description | Values |
|---|---|---|
transaction.heartbeat.interval.ms | The expected time between heartbeats to the transaction coordinator. Heartbeats can be used to ensure that a transactional producer remains alive and it is desirable to ensure liveness more frequently than the transaction.timeout.ms . When enabled, a transactional producer will send heartbeats at this interval to ensure that the transaction remains open before the coordinator proactively aborts it. If the transaction coordinator does not receive a heartbeat after 3 times this interval, it will proactively abort the transaction. | Default: 0 (disabled) |
