Abstract
A database system comprises: a data store containing a database comprising records ordered according to a first key field, and a search index of the first key field. The database system also comprises a replica data store, containing a replica copy of the database, with the records ordered according a second key field, different from the first key field, and a search index of the second key field. A server is configured to receive a request to access the records, and to access the records using the replica copy if the request includes a criterion based on values of the second key field.
