Example 1 with GroupIdNotFoundException

use of org.apache.kafka.common.errors.GroupIdNotFoundException in project kafka by apache.

the class KafkaStreamsNamedTopologyWrapper method removeNamedTopology.

/**
 * Remove an existing NamedTopology from a running Kafka Streams app. If multiple instances of the application are
 * running, you should inform all of them by calling {@code #removeNamedTopology(String)} on each client to ensure
 * it stops processing the old topology.
 * This method is not purely Async.
 *
 * @param topologyToRemove          name of the topology to be removed
 * @param resetOffsets              whether to reset the committed offsets for any source topics
 *
 * May complete exceptionally (does not actually directly throw) with:
 *
 * @throws IllegalArgumentException if this topology name cannot be found
 * @throws IllegalStateException    if streams has not been started or has already shut down
