Class InfinispanChatMemoryStore

java.lang.Object

dev.langchain4j.store.memory.chat.infinispan.InfinispanChatMemoryStore

All Implemented Interfaces:

ChatMemoryStore

public class InfinispanChatMemoryStore
extends Object
implements ChatMemoryStore

A ChatMemoryStore backed by an Infinispan cache.

Messages are serialized to JSON using ChatMessageSerializer and stored as strings, following the same approach as the other ChatMemoryStore implementations (Coherence, Cassandra, Oracle). The cache uses application/x-protostream encoding since strings are a native ProtoStream type.
