Abstract: A distributed database processing system for a database composed of data records organized into tables which processes unique index atoms consistently and concurrently. Each attempt to insert a new key value into such a unique index atom in any given node is routed to a unique index atom chairman for processing. The chairman determines whether the request will be granted. If the request is not granted, the requesting unique index atom continues to try to submit the insert. If the request is granted, the requesting unique index atom modifies the content thereof and broadcasts a replicated given unique index atom all other nodes that contain the replicated unique index atom.

Abstract: A distributed data processing system for a database composed of data records organized into tables for responding to a request to split an index in a consistent and concurrent fashion. A request to split an index atom at any given node is processed by a designated “chairman” for that index atom. The chairman splits its index by maintaining a lower portion thereof and by moving the contents of an upper portion to a newly created index atom as the right sibling. Each other node takes appropriate steps to assure orderly transfer of this information from the chairman consistently and concurrently across the distributed database processing system.
