> In new consumer on trunk, ConsumerRecords has method to retrieve records for given TopicPartition, but there is no method to retrieve TopicPartition's included/available in ConsumerRecords. Please have it supported.
> Method could be something like:
> {noformat}
> /**
>  * Get partitions of records returned by a {@link Consumer#poll(long)} operation
> */
> public Set<TopicPartition> partitions() {
>     return Collections.unmodifiableSet(this.records.keySet());
> }
> {noformat}
