Abstract
A database system is operable to determine a query for execution that requires access to a set of records stored by the database system. A first proper subset of the set of records are accessed in conjunction with executing the query by reading exactly one of a set of multiple replicas of each record of the first proper subset of the set of records from the replication-based storage system. A second proper subset of the set of records are accessed in conjunction with executing the query by reading at least one redundancy-coded segment from the redundancy-coding based storage system. A final resultant for the query is generated by performing at least one query operation on the first proper subset of the set of records and the second proper subset of the set of records in conjunction with executing the query.
