Abstract
A distributed data store includes a storage layer comprised of a plurality of storage nodes, each storage node configured to receive and queue table operations, and an aggregation layer comprised of aggregator nodes configured to route table operations to storage nodes in the storage layer and merge results of table operations returned by storage nodes in the storage layer. Each storage node includes in part scan threads dedicated to continuous and full scanning of segments of a table that are respectively associated with processor cores upon which such scan threads are running.
