The table SVL_QLOG holds the information regarding the cache usage. Amazon Redshift is the most popular cloud data warehouse today, with tens of thousands of customers collectively processing over 2 exabytes of data on Amazon Redshift daily. after setting this command: query run-times are still the same just like before setting this parameter. If enable_result_cache_for_session is off, Amazon Redshift ignores the results cache and executes all queries when they are submitted. If you don’t know how to turn off your result cache fear not. I know that to disable query caching I need to "SET enable_result_cache_for_session TO OFF". Cache Folders. The Redshift manages a table that stores all the information about if your query uses the cache. I would like to disable the query from using any cached results from prior queries. Result Caching. Every time a query is executed, the driver first checks if the result set associated with the query has already been cached in Redis. When the same query comes in against the same data, the prior results are retrieved from the cache and returned immediately, instead of rerunning the same query. Read the story. Components If a match is found in the result cache, Amazon Redshift uses the cached results and doesn't execute the query. In this post, we will review the steps needed to setup the DBLink on Amazon RDS. Redshift only supports fixed length fields so I don't see another way to preserve data integrity without replacing TEXT in the SQL schema to VARCHAR(N) where N is the longest string length for that column in the Dataframe. The 'use' parameter obviously controls if a query will utilize cached results. I am interested in performance testing my query in Redshift. While Redshift is rendering on the headless GPU, the system will still be 100% responsive so you can do other things – even open up another 3d app and continue working! These settings must be enabled at the service level via runtime properties to utilize cache, but can be controlled on a per query basis by setting them on the query context. It can asynchronously replicate your snapshots to S3 in another region for disaster recovery. These blocks that hold all the new changes are not sorted until you vaccume the database.
