Vaadin ComboBox: No way to define value change timeout to optimize DataProvider load
The current version of the Vaadin ComboBox does not have an option to define a value change timeout like it is possible in the TextField component.
The value change timeout would be a very efficient option to reduce the amount executed queries by the underlaying data provider of the ComboBox.
For example: If you have a ComboBox with a DataProvider connected to a large database, you do not really want to execute complex search queries on it right after every single character entered by the user. If there would be an option to define a value change timeout (e.g. 1s) the amount of executed queries will be heavily reduce and the ComboBox overlay will behave more fluent.
Created https://github.com/vaadin/vaadin-combo-box/issues/998 for adding a hardcoded debounce to CB data request.
Leaving this open as an enhancement for making that configurable.
