Abstract
A computer-implemented method includes receiving a request to transmit column group data to a target node, the column group data comprising C columns within a column-oriented data table and determining a transmission row count R for transmitting the column group data to the target node. The method may also include transmitting a transmission packet comprising R sequentially-ordered data elements for each of the C columns to the target node. The R data elements for each column may be sequentially retrieved from memory. A corresponding method includes receiving, at a target node, a request to receive the column group data, determining the transmission row count R for receiving the column group data, and receiving a transmission packet comprising R sequentially-ordered data elements for each of the C columns and storing the sequentially-ordered data elements within memory. A corresponding computer system and corresponding computer program products are also disclosed herein.
