摘要：A computer-implemented data processing system and method writes a first

plurality of copies of a data set at a first plurality of hosts and reads a second plurality ofcopies of the data set at a second plurality of hosts. The first and second pluralities ofcopies may be overlapping and the first and second pluralities of hosts may be

overlapping. A hashing function may be used to select the first and second pluralities ofhosts. Version histories for each of the first copies of the data set may also be written atthe first plurality of hosts and read at the second plurality of hosts. The version historiesfor the second copies of the data set may be compared and causal between the secondcopies of the data set may be evaluated based on the version histories for the secondcopies of the data set.
