Database optimization using special partition specifications for replicas

Abstract:

A method of modifying a database architecture to improve database performance is disclosed. A replication database table is generated from an original database table. The original database table is divided into a first plurality of partitions optimized for handling accesses for satisfying a first type of query. The replication database table is divided into a second plurality of partitions optimized for handling accesses for satisfying a second type of database query. Based on receiving the database query of the first type, the query of the first type is routed to one host of a plurality of hosts to satisfy the query, the one host hosting one of the first plurality of partitions; based on receiving the database query of the second type, the query is routed to the same or another host of the plurality of hosts to satisfy the query, the second host hosting one of the second plurality of partitions.
