Abstract
A journaled database may comprise a computing node that forms a local version of a global state, synchronized with respect to the high-water mark of a data node that maintains the global state. Instructions to modify the state that have been committed, subsequent to forming the local version of the state, may be represented in a merge signature. An uncommitted transaction may be checked for conflicts with respect to a last-ordered committed instruction to modify the data state. Validation with respect to earlier instructions represented by the merge signature may be skipped.
