Example 1 with Errors

use of io.confluent.kafkarest.Errors in project kafka-rest by confluentinc.

the class PartitionsResource method getOffsets.

/**
 * Returns a summary with beginning and end offsets for the given {@code topic} and {@code
 * partition}.
 *
 * @throws io.confluent.rest.exceptions.RestNotFoundException if either {@code topic} or {@code
 *     partition} don't exist.
 */
@GET
@Path("/{partition}/offsets")
@ResourceName("api.v2.partitions.get-offsets")
public void getOffsets(@Suspended AsyncResponse asyncResponse, @PathParam("topic") String topic, @PathParam("partition") int partitionId) {
    CompletableFuture<TopicPartitionOffsetResponse> response = partitionManager.get().getLocalPartition(topic, partitionId).thenApply(partition -> partition.orElseThrow(Errors::partitionNotFoundException)).thenApply(partition -> new TopicPartitionOffsetResponse(partition.getEarliestOffset(), partition.getLatestOffset()));
    AsyncResponses.asyncResume(asyncResponse, response);
}

Example 2 with Errors
