SWITCHING MODES OF OPERATION OF A ROW DISPERSAL OPERATION DURING QUERY EXECUTION

A database system is operable to execute a query based on, during a first temporal period, executing a multiplexer operation in conjunction with a first mode of operation to generate a first plurality of multiplexer output, and executing a load operation upon the first plurality of multiplexer output to generate initial load operation output from the first plurality of multiplexer output. In response to a determination to transition to execution of the multiplexer operation in conjunction with a second mode of operation, the multiplexer operation is further executed in conjunction with the second mode of operation during a second temporal period to generate a second plurality of multiplexer output for processing via the load operation. The load operation is further executed upon the second plurality of multiplexer output to generate further load operation output.
