    Hi Kishore,

    in general any filtering or limiting of the results returned by the external service should ideally be done in the external service itself to make sure the response payload only contains the data the is actually required. In case of OData therefore $filter and $limit should be used to only fetch the required number of results. So you should first check if the external service you're calling supports any such option to limit the number of results.

    For sure there might be cases where it is not possible to limit the number of results returned. There is currently no handlebars helper available for "slicing" an array and we're happy to hear your use-cases for this to consider adding one. What you could do today is to make use of the {{@index}} keyword inside the each-loop to only return something when the index is in a certain range (e.g. {{#lt @index 20}}...{{/lt}})

    Regards
