Abstract
An in-memory database system and method for administrating a distributed in-memory database, comprising one or more nodes having modules configured to store and distribute database partitions of collections partitioned by a partitioner associated with a search conductor. Database collections are partitioned according to a schema. Partitions, collections, and records, are updated and removed when requested by a system interface, according to the schema. Supervisors determine a node status based on a heartbeat signal received from each node. Users can send queries through a system interface to search managers. Search managers apply a field processing technique, forward the search query to search conductors, and return a set of result records to the analytics agents. Analytics agents perform analytics processing on a candidate results records from a search manager. The search conductors comprising partitioners associated with a collection, search and score the records in a partition, then return a set of candidate result records after receiving a search query from a search manager.
