Web22. apr 2024 · The execution time reported by Redshift is only 84ms, which is expected and pretty good with the table at ~33M rows. However, the total runtime, both observed on my local psql client as well as in Redshift's console UI is 5 seconds. I've tried the query on both a single node cluster and multi-node (2 nodes and 4 nodes) clusters.
