Zusammenfassung: | A method may include accessing a cache storing a graph index corresponding to a graph data in response to a transaction operating on the graph data. A cache miss triggered by a change to the underlying graph data may be detected. In response to detecting the cache miss, the graph index may be updated by at least replaying or rewinding one or more other changes made to the graph data by one or more other transactions between a first time of the transaction and a second time of a current version of the graph index in the cache. The graph index may be updated to avoid a full rebuild of the graph index. The transaction may be executed based on the updated graph index. Related systems and computer program products are also provided. |
