Delay Aware Querying With Seaweed
Overview Large highly distributed data sets are poorly supported by current query technologies. Applications such as endsystem-based network management are characterized by data stored on large numbers of endsystems, with frequent local updates and relatively infrequent global one-shot queries. The challenges are scale and endsystem unavailability. In such large systems, a significant fraction of endsystems, and their data, will be unavailable at any given time. Existing methods to provide high data availability despite endsystem unavailability involve centralizing, redistributing or replicating the data. At large scale these methods are not scalable. Seaweed is a scalable query infrastructure supporting online aggregation and completeness prediction. Seaweed is built on a Distributed Hash Table (DHT) but unlike previous DHT based approaches it does not redistribute data across the network.
