Motörhead Memory (Managed)
 Contents 
Setup
Motörhead Memory (Managed)#
Motörhead is a memory server implemented in Rust. It automatically handles incremental summarization in the background and allows for stateless applications.
Setup#
See instructions at Motörhead for running the managed version of Motorhead. You can retrieve your api_key and client_id by creating an account on Metal.
