Abstract
A node includes storage that stores a portion of high accessibility data corresponding to a shard that is divided into revisions. The portion of the high accessibility data is managed based on an activity state model including a writing state, a resolving state, a metadata update state, and a reading state. The node further includes a repository manager that obtains a cross-shard read request for the high accessibility data; makes a determination that the portion of the high accessibility data is not in the reading state; in response to the determination, adds the cross-shard read request to a delayed action queue at the revision of a last delayed action in the delayed action queue; and after processing the last delayed action in the delayed action queue and while in the resolving state: converts the cross-shard read request to a read request; and processes the read request.
