Create or update a memory
Introduced 2.12
Use this API to create or update a conversational memory for conversational search. A memory stores conversation history for the current conversation.
Once a memory is created, you’ll provide its memory_id to other APIs.
The POST method creates a new memory. The PUT method updates an existing memory.
When the Security plugin is enabled, all memories exist in a private security mode. Only the user who created a memory can interact with that memory and its messages.
