Interface KeyValueBytesStoreSupplier
- All Superinterfaces:
StoreSupplier<KeyValueStore<org.apache.kafka.common.utils.Bytes,
byte[]>>
public interface KeyValueBytesStoreSupplier
extends StoreSupplier<KeyValueStore<org.apache.kafka.common.utils.Bytes,byte[]>>
A store supplier that can be used to create one or more
KeyValueStore<Bytes, byte[]>
instances of type <Bytes, byte[]>.
For any stores implementing the KeyValueStore<Bytes, byte[]>
interface, null value bytes are considered as "not exist". This means:
- Null value bytes in put operations should be treated as delete.
- If the key does not exist, get operations should return null value bytes.
