Issue 4020: GCPR issue: Asynchronous COAS (coas-ftf)
Source:  (, )
Nature: Enhancement
Severity: 
Summary: The QueryAccess interface has a matching interface called AsynchAccess which mirrors many operations in QueryAccess except the data is returned asynchronously.  FCPR is looking at the ConstraintLanguage interface for doing population studies.  The time needed to find and return the data from these types of queries could be significant.  Yet these calls are synchronous.  It may be useful to mirror this interface with one that has corresponding asynchronous operations. Additionally, the interfaces could be expanded to allow for clients to check on the status of their request.

Asynchronous COAS
The QueryAccess interface has a matching interface called AsynchAccess
which mirrors many operations in QueryAccess except the data is
returned asynchronously.  FCPR is looking at the ConstraintLanguage
interface for doing population studies.  The time needed to find and
return the data from these types of queries could be significant.  Yet
these calls are synchronous.  It may be useful to mirror this
interface with one that has corresponding asynchronous
operations. Additionally, the interfaces could be expanded to allow
for clients to check on the status of their request.
