An elastic parallel database system where data distribution is container- and container-context based. Container Based Tables are defined and Container Member Tables achieve co-location of data as needed. A polymorphic key may also establish polymorphic key relationships between rows in one table and rows in many other possible tables.

Advancements in data distribution methods and referential integrity

An elastic parallel database system where metadata is specified out-of-band during database operations via a set of augmentation rules. The rules are used to augment or modify commands received, and indicate whether they are to be used for specific connections on which they are received, for all client connections, or some other scope.

Out-of-band specification of metadata during database operations

Newly added, deleted, or changed data of a local storage in a distributed database system is prevented from being replicated until it has been approved via a specific process. Any new, deleted, or changed records are initially marked as being candidate data. The normal replication processing within the distributed database system ignores such data. In this way, the candidate data is not allowed to leave its source site, and potentially contaminate the rest of the replication network, until that data has been approved. The approval process is provided by a candidate data scanner that detects the candidate data and provides it to a candidate data resolver for processing. The candidate data resolver is architected to provide for per installation extensibility.
