Abstract
Data are received at a worker system in a distributed computing system that describe a graph representing relationships among a set of items. The graph models a condition having an associated problem. The graph has graph components having associated data fields. The received data are stored in a backup table, and the relationships are analyzed to identify a solution to the problem. As part of the analysis, a new value for the data field associated with a graph component is identified and compared with an existing value of the data field, and the data field is modified. The modified data field is stored in a delta table representing a change to the backup table.
