- Tera-Tom Coffing
1)Random - Round Robin Distribution (Default)
Most Kognitio tables will use a Round robin distribution. This is the default when no distribution key is defined. The data is spread evenly across the nodes to maximize parallel processing.
Hash distribution. A column(s) are chosen as the distribution key. This column(s) is run through the Kognitio hashing algorithm to divide data among all of the nodes. Like values will hash to the same node. This is often done when two tables are joined together. When the join key is also the distribution ...
