Memory Database node
A lightweight in-memory store with save and read operations — state between nodes or runs without provisioning any external database.
Memory Database (memory) keeps small state inside the platform: save values in one part of a flow (or one run) and read them in another. For durable, queryable data use the Database node.

Configuration
Open the node (double-click) to edit it. Key fields:
- Node ID / Name — the identifier used in variables and the display name on the canvas.
- Operation — save or read.
- Key / value — what to store or retrieve (variables allowed).
Inputs & outputs
Save receives a value and emits confirmation; read emits the stored value. Downstream nodes reference its output with {{node_id.field}} — see the variables reference.
