Abstract
Performing optimized update operations in in-memory database systems. Update values corresponding to a source table of values stored on an in-memory database are identified by an in-memory database computer system based on information from a computer system implementing a software application. The update values are distributed across a plurality of rows, each row including a plurality of column attributes. At least some column attributes of the plurality of column attributes include values updated relative to corresponding column attributes in the source table of values. A row of the update values is identified. The row includes a plurality of column attributes, each column attribute having a respective value. Each value of each column attribute of the row of the update values is the same as a corresponding value of a corresponding attribute of a corresponding row of the source table is determined. Upon such a determination, a corresponding row of the source table stored on the in-memory database is written into the in-memory database by the in-memory database computer system.
