Abstract
In an approach, a database management system logically partitions a database object (such as a table) across multiple pluggable databases of a container database. When a database server receives a query at an application root, the database server consults a container map which provides a mapping between a set of partitioning criteria and a set of member pluggable databases of the application root. Using the container map, the database server identifies one or more pluggable databases of the set of member pluggable databases of the application root that contain records which potentially have the ability to match the predicates of the query. The database server then limits the execution of the query to the identified pluggable databases, effectively pruning away records contained by the other pluggable databases to increase the efficiency of executing the query.
