Conditional Forwarding

After processing the data, conditional forwarding is doable based on the Tags returned in the result. Below is list of different logic operations that can be done on tags. - and - forwards the message if all the tags specified are present in Message's tags. - or - forwards the message if one of the tags specified is present in Message's tags. - not - forwards the message if all the tags specified are not present in Message's tags.

For example, there's a UDF used to process numbers, and forward the result to different vertices based on the number is even or odd. In this case, you can set the tag to even-tag or odd-tag in each of the returned messages, and define the edges as below:

edges:
  - from: p1
    to: even-vertex
    conditions:
      tags:
        operator: or # Optional, defaults to "or".
        values:
          - even-tag
  - from: p1
    to: odd-vertex
    conditions:
      tags:
        operator: not
        values:
          - odd-tag
  - from: p1
    to: all
    conditions:
      tags:
        operator: and
        values:
          - odd-tag
          - even-tag
