Abstract
Techniques provided herein allow for estimating data missing in query results provided in response to queries performed on data managed by a data management system. In the event that one or more leaf nodes are unable or unavailable to process a query, a final query result provided in response to the original query may be missing data that exists on those leaf nodes. A data accounting service monitors what managed data is being stored on the leaf nodes and on what leaf node. The data accounting service can estimate how much data is missing from a final query result when one or more of the leaf nodes are unable or unavailable to process a query.
