Documentation

• Class name: CacheBackendData __Inspire
• Category: InspirePack/Backend
• Output node: True

The CacheBackendData node is designed to cache arbitrary data along with a unique key and a descriptive tag in a backend storage system. This functionality supports efficient data retrieval and management by allowing users to store and access data based on unique identifiers and descriptive tags.

Input types

Required

• key
  • The 'key' parameter serves as a unique identifier for the data being cached. It is crucial for retrieving the cached data at a later time.
  • Comfy dtype: STRING
  • Python dtype: str
• tag
  • The 'tag' parameter provides a short description for the cached data, aiding in its identification and retrieval.
  • Comfy dtype: STRING
  • Python dtype: str
• data
  • The 'data' parameter is the actual data to be cached. It can be of any type, making this node versatile in its application.
  • Comfy dtype: *
  • Python dtype: Any

Output types

• data opt
  • Comfy dtype: *
  • Returns the data that was cached, allowing for immediate verification or further processing.
  • Python dtype: Tuple[Any]

Usage tips

• Infra type: CPU
• Common nodes: unknown
