US 2018/0322301 A1 · COMMIT AND ROLLBACK OF DATA STREAMS PROVIDED BY PARTIALLY TRUSTED ENTITIES

Abstract

A collection of key-value pairs may be maintained by a key-value database management system. Updates to the collection may be provided by a partially trusted entity. The updates to the collection may be stored in a series of transactions that are committed synchronously but associated with a second version of the collection of key-value pairs that is not immediately visible to a data consumer. The second version of the collection may initially be associated with an unaccepted state. The second version may be accepted and made available to the data consumer, or rejected and rolled back to the previous version.
