1. A computer-implemented method of providing data objects to a database system that includes multiple processing units in one or more database nodes that each include at least one processor operable to process at least a portion of data for the database system, wherein at least one of the database nodes includes first and second processing units, and first and second local storages that can be accessed only by the first and second processing units, respectively, and wherein the computer-implemented method comprises: obtaining one or more data objects, pertaining to metadata for data associated with the database system, to be provided to least the first and second processing units of the at least one database node of the database system; and storing or at least facilitating storage of a copy of the one or more objects in each one of the first and second local storages for access only by the first and second processing units, respectively, thereby allowing each one of the first and second processing units to access its own copy of the one or more database objects without sharing its own copy with the other one of the first and second processing units.
