[jira] Created: (TAP5-902) GridDataSource does not allow performing
less than 2 queries if returning results
GridDataSource does not allow performing less than 2 queries if returning results
---------------------------------------------------------------------------------
Key: TAP5-902
URL: https://issues.apache.org/jira/browse/TAP5-902
Project: Tapestry 5
Issue Type: Improvement
Components: tapestry-core
Affects Versions: 5.1.0.5
Reporter: Dan Adams
By having getAvailableRows() and prepare() separate, any implementation is forced to perform 2 queries. Many systems allow getting the results of a query and the total count in one query so that you don't have to perform 2 queries. Getting around this requires some pretty gross hacks (unless you just don't use grid at all which is unfortunate).

-------------------------------------------
This may be possible by changing some of the semantics of the GDS interface; i.e., prepare() called before getAvailableRows().
