> +Question:+
> Pagination in subscription
> +Description:+
> I have an operator that performs subscriptions for specific types of orion entities. 
> However, although i use the relevant field (limit) in the options object i push for the subscription, data still arrive paginated at 20 elements (I would like to increase it). Is pagination (limit) option valid only for query operations, or is it available for subscriptions as well?
> Here is my code:
> var subscribe = function subscribe() {
>     this.connection = new NGSI.Connection(this.ngsi_server, {
>         ngsi_proxy_url: this.ngsi_proxy
>     });
>     var attributeList = null;
>     var duration = this.subscriptionUpdateRate;
>     var throttling = null;
>     var notifyConditions = [{
>             'type': 'ONCHANGE',
>             'condValues': this.condValues
>         }];
>     var options = {
>         flat: true,
>         limit: 999,
>         onNotify: function(data) {
>             handlerReceiveEntity(data);
>         },
>         onSuccess: function(data) {
>             ....
>             window.addEventListener("beforeunload", function() {
>                 this.connection.cancelSubscription(this.subscriptionID);
>             }.bind(this));
>         }.bind(this)
>     };
>     this.connection.createSubscription([this.entities], attributeList, duration, throttling, notifyConditions, options);
> };
> Still, I am getting only 20 entities instead of ~40 when the function is first invoked. Any idea what might be wrong?
> The version of Orion is 0.14.0.
