Time and value ordering may be applied for items stored in data backups. A change log that persists changes to a data set may be updated with changes and used to update an in-memory table for the data set, which describes changes to items up to a current time. An event may be detected to seal the in-memory table from subsequent updates and a persistent data object that orders the items in the in-memory according to both keys of the respective items and the respective time values of the items, as stored in the change log, may be generated and stored as part of a backup for the data set.

Systems and methods are provided for generating an index of a set of vectors as a distributed proximity-based graph data structure comprising representative vectors corresponding to subsets of the set of vectors, storing the set of vectors across a plurality of storage devices of a distributed storage system based on the distributed proximity-based graph data structure, and loading, in response to a vector query, a plurality of subsets of the set of vectors from the distributed storage system based on the distributed proximity-based graph data structure.
