receiving, by a client device of a group of client devices, from a server device comprising a database, an indication that the client device has been selected as a primary client device of the group of client devices;

obtaining, by the client device, a first set of queries to the database from a plurality of other client devices of the group of client devices;

generating, by the client device, a second set of queries by normalizing the first set of queries;

determining, by the client device, a set of access paths corresponding to the second set of queries, wherein at least one access path of the set of access paths comprises at least one path for retrieving first data from the database previously retrieved and currently stored on at least one client device of the plurality of other client devices, and wherein at least one access path of the set of access paths comprises at least one path for retrieving second data currently stored in the database on the server device;

determining, by the client device, based on a resource usage cost analysis, that retrieving the first data from the at least one client device of the plurality of other client devices has a lower resource usage cost than retrieving the first data from the server device; and

retrieving, by the client device, based on the set of access paths, data comprising the first data from the at least one client device of the plurality of other client devices and the second data from the server device.
