In-Memory DB Plugin

The In-Memory DB plugin provides a pure in-memory database adapter for Eliza agents. All data is ephemeral and lost when the process exits.

Package: @elizaos/plugin-inmemorydb

Category: Database

Overview

This plugin implements the elizaOS database adapter interface entirely in memory, with no disk I/O and no external dependencies. It is useful for testing, development, stateless agents, and scenarios where persistence is not needed or desired. All stored data is lost when the agent process terminates.

Installation

eliza plugins install inmemorydb

Configuration

No environment variables or configuration required. The plugin works out of the box once installed.

When to Use

• Testing — Fast setup and teardown with no cleanup needed
• Development — Quick iteration without managing database files or servers
• Stateless agents — Agents that do not need to remember past interactions
• Ephemeral sessions — Short-lived agents where persistence adds no value
