------------------------------------
Summary: Improve Grid implementation for "slow" data sources
Key: TAP5-2589
URL: https://issues.apache.org/jira/browse/TAP5-2589
Project: Tapestry 5
Issue Type: Improvement
Components: tapestry-core
Reporter: Jochen Kemnade
When using a Grid that's backed by a data source for which performing a count
is expensive, performance is quite bad.
There are some places where Grid (and subcomponents) call
{{getAvailableRows()}} to determine whether the data source is empty or has (at
least) a specific number of results. We should provide (and use) more specific
and efficient methods in {{GridDataSource}}.
