PoolID is an arbitrary identifier used in the activity methods Load-DataPage and Call-Async-Activity to help manage asynchronous data loading.
Use PoolID to group child requestors as one: the system waits until all requestors with the same PoolID are finished before proceeding.
PoolID exists in the context of the activity using it, so you can have identical PoolID values in different activities without causing a problem.
PoolID can be any valid String, a property reference, or a parameter.
