No. Or at least theoretically not.

You can try the `BrokerMetadataInterceptor` feature, which is already used in [KoP](https://github.com/streamnative/kop).

```properties
brokerEntryMetadataInterceptors=org.apache.pulsar.common.intercept.AppendIndexMetadataInterceptor
```

Then you can use the `Message#getIndex` API to get the index, which is similar to Kafka's offset.
