Event app last part Flashcards
What functionality is needed to send newsletters to people who have bought tickets?
The Event manager should be able to create newsletters and send them automatically based on scheduled events.
How can scheduled events be configured to execute a microflow at a specific moment in time?
Scheduled events can be configured to execute a microflow at a specific moment in time and can be repeated at intervals such as hours days or minutes.
What is the behavior of a scheduled event with an interval of one year?
If an interval of a year is given the scheduled event will be triggered every 365 days not precisely every year.
Where can scheduled events be enabled/disabled for production environments?
For production environments scheduled events can be enabled/disabled via the appropriate tools like Cloud Portal Windows Service Console etc.
What is the purpose of loops in Mendix microflows?
Loops are used to iterate over a list of objects executing the flow inside the loop for every object in the list.
What elements can a loop contain in a Mendix microflow?
A loop in Mendix can contain all elements used in normal microflows with the exception of start and stop events. It can also contain break and continue events.
What does a break event do in the context of a loop in Mendix?
A break event in a loop will stop the iteration over the list.
What is the iterator in the context of a loop in Mendix?
The iterator in a loop is the object over which the loop iterates resembling an input parameter of a microflow.
How are aggregate functions used in Mendix microflows?
Aggregate functions such as Aggregate List are used to calculate aggregated values like maximum minimum sum average and count total amount over a list of objects.
In what scenario can aggregate functions be combined with a retrieve action for optimization?
Aggregate functions can be combined with a retrieve action resulting in an optimized retrieve from the database especially when calculating values like count after retrieval.
What are batches used for in Mendix?
Batches in Mendix are used when large amounts of data need to be processed breaking up the full data set into smaller parts to update subsets of records one at a time.
How can batch retrieves be configured to manage the size of the data processed in Mendix?
Batch retrieves in Mendix can be configured using the Custom range option in a retrieve action allowing you to set limits on the batch size to avoid negative impacts on performance.
How can you have a microflow automatically run at a specific moment in time?
Create and enable a scheduled event.
What can you use to exit a loop early instead of finishing the entire list of iterator objects?
break event
You want to find the total number of objects in a list. What can you easily use to do this?
Use an aggregate list function.
