What Is A Distribution Key In Redshift. Distribution key could be of two types, 'even' or 'all'. It helps optimize query performance by. The values in one column are used to determine the row distribution. Key requires a single column to be defined as a distkey. Redshift dist keys determine where the data is stored in redshift. Distribution keys are used for achieve following. Using the distkey is basically you letting rs know the way it will distribute the data (i.e a table) through the slices, in this case using a column as a key and storing the rows. Distkey is a column designation that determines how data is distributed across compute nodes in a redshift cluster. On ingest, amazon redshift hashes each distkey column value, and route hashes to the same slice consistently. Optimize table distribution with auto, even, key, or all styles. Read on to learn more about. Redshift will attempt to place matching values on the same node slice. If the table grows larger and none of the columns are suitable to be the distribution key, amazon redshift changes the distribution style to even. Choosing the right distribution styles help in optimising redshift performance. Avoid frequent updates for all.
