Abstract
A journaled database system may comprise data nodes that collectively maintain a collection of data and provide clients with read and write access to the collection. Correlated classification functions may be associated with read and write operations, such that items affected by a write operation are classified similarly to items accessed during a read operation. Read and write signatures may be formed based on the classification. Conflicts may be detected by comparing the read and write signatures for equivalent or overlapping classifications.
