One or more techniques and/or systems are disclosed herein for aggregating web-based data stored in a distributed data store so that it can be retrieved in a first-in, first-out (FIFO) manner. A unique aggregation key is generated for respective one or more data generated from a web-based event, where the one or more data are added to the distributed data store, and the aggregation key corresponds merely to the data generated from the web-based event. The one or more data from the web based event is aggregated in a FIFO queue and stored in a same partition of the distributed data store, based on the aggregation key.
