Method Details

setD2ControllerClient

protected void setD2ControllerClient(D2ControllerClient d2ControllerClient)

setConsumer

protected void setConsumer(PubSubConsumerAdapter consumer)

getChangelogConsumer

public <K,
V> VeniceChangelogConsumer<K,V> getChangelogConsumer(String storeName)

Default method to create a VeniceChangelogConsumer given a storeName.

getChangelogConsumer

public <K,
V> VeniceChangelogConsumer<K,V> getChangelogConsumer(String storeName,
 String consumerId)

getChangelogConsumer

public <K,
V> VeniceChangelogConsumer<K,V> getChangelogConsumer(String storeName,
 String consumerId,
 Class<V> valueClass)

Creates a VeniceChangelogConsumer with consumer id. This is used to create multiple consumers so that each consumer can only subscribe to certain partitions. Multiple such consumers can work in parallel.

getChangelogConsumer

public <K,
V> VeniceChangelogConsumer<K,V> getChangelogConsumer(String storeName,
 String consumerId,
 Class<V> valueClass,
 String viewNameOverride)

getStatefulChangelogConsumer

public <K,
V> StatefulVeniceChangelogConsumer<K,V> getStatefulChangelogConsumer(String storeName)

getStatefulChangelogConsumer

public <K,
V> StatefulVeniceChangelogConsumer<K,V> getStatefulChangelogConsumer(String storeName,
 Class<K> keyClass,
 Class<V> valueClass,
 org.apache.avro.Schema valueSchema)

Parameters:

keyClass - The SpecificRecord class for your key

valueClass - The SpecificRecord class for your value

valueSchema - The Schema for your values

getStatefulChangelogConsumer

public <K,
V> StatefulVeniceChangelogConsumer<K,V> getStatefulChangelogConsumer(String storeName,
 Class<V> valueClass)

getVersionSpecificChangelogConsumer

public <K,
V> VeniceChangelogConsumer<K,V> getVersionSpecificChangelogConsumer(String storeName,
 int storeVersion,
 boolean includeControlMessages)

getVersionSpecificChangelogConsumer

public <K,
V> VeniceChangelogConsumer<K,V> getVersionSpecificChangelogConsumer(String storeName,
 int storeVersion,
 boolean includeControlMessages,
 boolean deserializeReplicationMetadata)

Subscribes to a specific version of a Venice store. This is only intended for internal use.

getVersionSpecificChangelogConsumer

public <K,
V> VeniceChangelogConsumer<K,V> getVersionSpecificChangelogConsumer(String storeName,
 int storeVersion)

Creates a version specific changelog consumer without control messages.

getPubSubConsumer

protected static PubSubConsumerAdapter getPubSubConsumer(ChangelogClientConfig changelogClientConfig,
 PubSubMessageDeserializer pubSubMessageDeserializer,
 String consumerName)

setViewClassGetter

protected void setViewClassGetter(VeniceChangelogConsumerClientFactory.ViewClassGetter viewClassGetter)

deregisterClient

public void deregisterClient(String consumerName)

Removes client from the map, so it be cleaned up by Garbage Collection
