Parameter resolution in sub-nodes

Sub-nodes behave differently to other nodes when processing multiple items using an expression.

Most nodes, including root nodes, take any number of items as input, process these items, and output the results. You can use expressions to refer to input items, and the node resolves the expression for each item in turn. For example, given an input of five name values, the expression {{ $json.name }} resolves to each name in turn.

In sub-nodes, the expression always resolves to the first item. For example, given an input of five name values, the expression {{ $json.name }} always resolves to the first name.

节点参数(Node parameters)#

  • 会话密钥：输入用于在工作流数据中存储记忆的密钥。
  • 会话存活时间：使用此参数可以让会话在指定秒数后过期。
  • 上下文窗口长度：输入要考虑的前一次交互的数量以获取上下文。

单内存实例(Single memory instance)#

If you add more than one Redis 聊天内存 node to your workflow, all nodes access the same memory instance by default. Be careful when doing destructive actions that override existing memory contents, such as the override all messages operation in the Chat Memory Manager node. If you want more than one memory instance in your workflow, set different session IDs in different memory nodes.
