<Icon name="Blocks" aria-hidden="true" /> [**Bundles**](/components-bundle-components) contain custom components that support specific third-party integrations with Langflow.
|
|
|
|
This page describes the components that are available in the **Redis** bundle.
|
|
|
|
## Redis Chat Memory
|
|
|
|
The **Redis Chat Memory** component retrieves and stores chat messages using Redis memory storage.
|
|
|
|
Chat memories are passed between memory storage components as the [`Memory`](/data-types#memory) data type.
|
|
|
|
For more information about using external chat memory in flows, see the [**Message History** component](/message-history).
