Abstract

Techniques are disclosed for delivering push subscription notifications in large scale distributed systems. Subscription notifications can be delivered to mobile devices of subscribing users by monitoring, at a server, an application database comprising a data record having one or more data values, detecting, at the server, in accordance with the monitoring, a changed data value, querying a subscription database for a subscription having at least one constant value to be compared to the changed data value in accordance with a trigger condition specified in a trigger template, determining whether the trigger condition is true using the changed data value and the constant value as the values of the first and second variables, respectively, in the at least one comparison; and pushing a notification from the server in response to the trigger condition being true.
