Wait Action Configuration
What is a Wait Action?
Wait actions hold any records passed into them until all previous actions 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.
In PhixFlow v12.1+, the Wait action does pass through the last received record, in addition to the count attribute, once it has finished processing all input records.
For the full list of Wait action Properties, see Wait Action Properties.
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 contains a count of the number of records received, produced once all previous actions have completed their processing
- Always generates an 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 (PhixFlow v12 and older)
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 actions in the iteration have completed their processing. This is regardless of the number of input records (including 0).
For more on Loops, see 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 action or other action to the Wait action's input connection point
- Connect the output action or other action 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. For example, new records must be saved before continuing and View Action is used post Wait Action to then continue processing.
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
