Fine grained data store management

[damiengarbarino]

Currently the calendar is loading the entire data set contained by the store.
This is inefficient, especially with asynchronous stores like JsontRest store.
A better way to manage data would be to:

• add to the query options the time range to display (start & end time) automatically
• provide a function to set to a SimpleQueryEngine that tests if a data item is in the displayed time range.

In addition, a new cache class that takes a master store could be provided to query this master store for a greater time range and allow local navigation when the data is already loaded. This duration of this time range would be configurable.

having the calendar query a time range automatically would be immensely useful!! I'm tying the calendar into a lot of historical event data in one of my projects and have been struggling with how best to deal with this exact problem.

This is possible but not convenient using the 1.9 code.
You can rely on the "timeIntervalChange" event and set a new store with a new query to the calendar.

This feature is the next priority to be implemented.

Has there been any progress on this feature ?

Hi Johan,
This feature is not implemented yet (otherwise it would have been merged with the master). The data branch contains a POC but it's not complete yet. There are some issues that are not resolved yet (too many item > render item conversions for example) but it's running.
