Description copied from interface: AvroGenericStoreClient

Get the values associated with the given keys and return them in a map of keys to values. Note that the returned map will only contain entries for the keys which have a value associated with them.

Returns:

Throws:

VeniceClientException

streamingBatchGet

public void streamingBatchGet(Set<K> keys,
 StreamingCallback<K,V> callback)
                       throws VeniceClientException

Description copied from interface: AvroGenericStoreClient

Streaming interface for AvroGenericStoreClient.batchGet(Set). You can find more info in StreamingCallback.

Throws:

VeniceClientException

start

public void start()
           throws VeniceClientException

Throws:

VeniceClientException

close

public void close()

Description copied from interface: AvroGenericStoreClient

Release the internal resources.

getStoreName

public String getStoreName()

getKeySchema

@Deprecated
public org.apache.avro.Schema getKeySchema()

Deprecated.

Description copied from interface: AvroGenericStoreClient

Get key schema.

getLatestValueSchema

@Deprecated
public org.apache.avro.Schema getLatestValueSchema()

Deprecated.

Description copied from interface: AvroGenericStoreClient

Get the latest value schema known in current store client. This function doesn't guarantee it will return the latest schema if you add a new value schema when current store client is running.

startWithExceptionThrownWhenFail

public void startWithExceptionThrownWhenFail()

Description copied from class: InternalAvroStoreClient

This method is mainly for internal use. The default {#start()} method will not throw an exception if the client fails to start since it is a best effort to make it compatible with the existing usage of the client (customers can trigger the start() method even before the dependency is ready). This method is mainly used to the internal startupAware callback, and it will indicate the startup failure by throwing an exception.
