How To Define Sort Key In Redshift. Defining a table with a sort key results in the physical ordering of data within each slice, based on the sort type and the columns chosen in the key definition. When you define a compound sort key, make sure to put as first in the list, the most frequently used column in your queries. Selecting and maintaining sort keys can be time consuming, but are key actions to improving the performance of your amazon. Load your data in sort key order to avoid needing to vacuum. If each batch of new data follows the existing rows in your table,. With the new alter sort key command, users can dynamically change the redshift table sort keys as needed. Compound sort keys work best in situations where the query’s. In amazon redshift, we allow for a table to be defined with compound sort keys, interleaved sort keys, or no sort keys. To define a sort type, use either the interleaved or compound keyword with your create table or create table as statement. A sort key is a field in your redshift database table that determines the order in which the data is physically stored in the database.
