Query Caching

[sitefinitysteve]

I've been heavily relying on the following: http://code.google.com/p/jquery-jsonp/

Can the Kendo DS do this as well by any chance?  The performance gained from the cache is AMAZING.

Hello Steve,

Indeed, our data source provides means for caching, it can be enabled on transport:

var dataSource = new kendo.data.DataSource({
     transport: {
        cache: "inmemory"
       //...
       }
     }
 });

Currently only available option is in-memory cache.All the best,

Can you elaborate on how the caching mechanism works?

...does it store query results and just fetch from local if the query is the same?...cleared on postback?...?

Hello Steve,

Indeed, the query arguments are used as key, if this key matches data is extracted from the cache and server is not requested.
The cache will be cleared if page is refreshed.

Fantastic, hopefully rendered this extra plugin useless for me! :) (the google one)

Where's the documentation on this?

Hello Steve,

I'm afraid that currently there is not documentation on this exact property. Please excuse us for the inconvenience.

Hi,

I'm having problems with datasource read transport. I need to fetch data on real-time, when it fetches data from database it says it's from the cache, I try to debug it with google chrome. I need to disable caching. Could you please help me?

This is late, but I thought I'd post it anyway.

Salvador, to disable cacheing, set cache: false. See here: http://docs.kendoui.com/api/framework/datasource#configuration-transport.read.cache-Boolean

You can do this per specfic CRUD operation within transport. Setting cache to false will also append a timestamp parameter to your request.
