Redshift Sort Key Temp Table at Sha Jarrell blog

Redshift Sort Key Temp Table. To get redshift to do the merge join you will need to sort and analyze your temp tables which will cost much more time than the savings. Amazon redshift’s distkey and sortkey are powerful tools for optimizing query performance. Specify timestamp column as sort key to skip entire blocks outside. Redshift stores data on disk in sorted order according to the sort key, which has an important effect on query performance. With the new alter sort key command, users can dynamically change the redshift table sort keys as needed. To view the sort keys for a table, query the svv_table_info system view. In other words, to create a redshift temp table, simply. The following example creates a temporary table called tempevent, which inherits its columns from the event table. Users can either use the temp keyword or a # sign right before the table name to create a temporary table (redshift temp table). Because redshift is a columnar database with compressed storage, it doesn't.
