Abstract
A snapshot manager examines a set of entries of a journal of a multi-data-store storage system. Each entry is formatted in a data-store-independent transaction language and various entries contain a respective indication of a committed change to a data object or to a journal schema. Corresponding to various data objects that are materialized at least at a data store of the storage system, respective compact state change representations are generated based on the set of journal entries affecting the data objects. A given compact state change representation, also formatted in the transaction language, may represent cumulative effects of several changes. A snapshot of the journal, comprising the compact state representations, is stored.
