Redshift Sort Key Vs Distribution Key at Alyssa Coode blog

Redshift Sort Key Vs Distribution Key. Distkey is a column designation that determines how data is distributed across compute nodes in a redshift cluster. Create table activity ( id integer primary key, created_at_date distkey, device varchar(30) ) sortkey (created_at_date, device); When the table grows larger, amazon redshift might change the distribution style to key, choosing the primary key (or a column of the. Redshift stores data on disk in sorted order according to the sort key, which has an important effect on query performance. A compound sort key is more efficient when query predicates use a prefix, which is a. It helps optimize query performance by. Our query runs on this table in 5 seconds , a 38% improvement over the previous table, and a 2x improvement from the naive query!
