Polyvalues

Warren A. Montgomery
1979 Proceedings of the seventh symposium on Operating systems principles - SOSP '79  
The coordination of atomic updates to distributed data is a difficult problem in the design of a distributed information system.  ...  A common goal for solutions to this problem is that the failure of a site should not prevent any processing that does not require the data stored at that site.  ...  ACKNOWLEDGEMENTS I would like to thank the members of the Computer Systems Research group of the M.I.T. Laboratory for Computer Science for their support during the research that lead to this paper.  ...

Concurrency control: methods, performance, and analysis

Alexander Thomasian
1998 ACM Computing Surveys  
The second execution phase is shorter since no disk I/O is required, resulting in a lower effective degree of txn concurrency and less data contention.  ...  : special methods for indices and aggregate data; modified txn structures; and relaxed levels of consistency for queries; (vi) survey performance evaluation studies of CC methods; (vii) illustrate the  ...  Polyvalues provide a similar capability for coping with failures in a distributed database environment through a bookkeeping tool described in Montgomery [1978] .  ...
