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:
  1. Null value bytes in put operations should be treated as delete.
  2. If the key does not exist, get operations should return null value bytes.
