Scalable update propagation via query aggregations and connection migrations
Methods, systems, computer-readable media, and apparatuses for combining nodes and/or aggregating streaming queries in a simulation are presented. In some examples, combining nodes and/or aggregating streaming queries may result in less duplicative data being sent through the system. A first node may be connected to a first aggregator, and the first aggregator may be connected to a second node. In some examples, the first node may comprise a client or another aggregator, and the second node may comprise a data source or another aggregator. Based on a determination that a first streaming query subscription of the first node connected to the first aggregator has changed to a second streaming query subscription, one or more aggregator controller(s) may determine to migrate the first node to a different aggregator. Migrating the first node to a different aggregator may increase overlap of streaming query subscriptions in the system and/or reduce the amount of duplicative data being sent through the system.
