Type Parameters:

K - the type parameter

V - the type parameter

All Superinterfaces:

AutoCloseable, Map<K,V>

All Known Subinterfaces:

NavigableKeyValueStore<K,V>

```
public interface KeyValueStore<K,V>
extends Map<K,V>, AutoCloseable
```
A Key-Value store is a database in which data is associated with a unique key providing quick retrieval via the key. Key-Value Stores are created using connect(String) where the specification is defined as follows: kv::[type]::[namespace]::[path];compressed=[true,false];readOnly=[true,false]
