2.18 Wait Action Configuration
This action is available in PhixFlow version 11.2+.
What is a Wait Action?
Wait actions hold any records passed into them until all previous action nodes have finished processing. The Wait action then outputs a count attribute containing the sum of all records it has received but it does not pass through any of the attributes it has received.
Action Setup
Input Connection Points: A single input connection point containing no mappings and no ability to create mappings
- Output Attributes: A pre-configured count output attribute which automatically calculates the sum of all records it has received, once all previous action nodes have completed their processing
- Always generate a single output record regardless of the number of input records (including 0)
- Output Connection Points: can have any number of output connection point(s) which can be used to pass the count attribute to other action(s)
- does not pass through any of the attributes it has received.
Considerations
When a Wait action is used inside of a Loop, it generates a single output record for each iteration of the loop, once all action nodes in the iteration have completed their processing. This is regardless of the number of input records (including 0).
For more on Loops, see 3.08 Loop Action Configuration.
Creating Wait Actions
- Click and drag the Wait icon in the toolbar onto the canvas
- Enter a name for the Wait action, then select Create Action
- Connect the input node or other action node to the Wait action's input connection point
- Connect the output node or other action node to the Wait action's output connection point
- The Mappings window will open where the count attribute can be mapped out
Example Uses
The Wait action is useful in a number of use cases.
- Where multiple records require complex processing and only once this has finished, a separate single process is required
Handling special case logic for where connectors receive no records, e.g. Gateway actions, For Each actions or View actions returning no response records, or no records in a grid
With parallel connectors and a Converge action - where you need to output a final record after all other actions have completed, such as, to trigger the end of a transaction, or to write out a final end record
