Method Details

consume

public void consume(Runnable signalsInterrupt)

Description copied from interface: Consumer

Consume **must** make sure that interrupted status is restored as it is needed for stopping unhealthy consumers. Swallowing the interrupt by consume or any of its dependencies will result in consumer being marked as unhealthy and will prevent commits despite messages being sent to subscribers.

Specified by:

consume in interface Consumer

initialize

public void initialize()

Specified by:

initialize in interface Consumer

tearDown

public void tearDown()

Try to keep shutdown order the same as initialization so nothing will left to clean up when error occurs during initialization.

Specified by:

tearDown in interface Consumer

updateSubscription

public void updateSubscription(pl.allegro.tech.hermes.api.Subscription newSubscription)

Specified by:

updateSubscription in interface Consumer

updateTopic

public void updateTopic(pl.allegro.tech.hermes.api.Topic newTopic)

Specified by:

updateTopic in interface Consumer

commit

public void commit(Set<SubscriptionPartitionOffset> offsets)

Specified by:

commit in interface Consumer

moveOffset

public boolean moveOffset(pl.allegro.tech.hermes.common.kafka.offset.PartitionOffset offset)

Specified by:

moveOffset in interface Consumer

getSubscription

public pl.allegro.tech.hermes.api.Subscription getSubscription()

Specified by:

getSubscription in interface Consumer
