extjs - Sencha Touch - Is creating Stores often expensive? -

is expensive operation create ext.data.store objects, because quite create stores retrieving info once.

it depend on quantity of info you're retrieving , how utilize in application.

you need weigh overheads calling info datasource more once, overhead of storing on page , using client side.

using stores retrieve info 1 time isn't problem store client side d collection of data. there isn't much weight them.

it may worth knowing if you're using extjs4 , you're talking retrieving single info item, rather collection of items, can create single 'model' , interact rather store, lighter solution.
