Your client connection to the database appears to hang or timeout when running long queries, such as a COPY command. In this case, you might observe that the Amazon Redshift console displays that the query has completed, but the client tool itself still appears to be running the query. Th...
With manual WLM, you can manage system performance and your users' experience by modifying the WLM configuration to create separate queues for the long-running queries and short-running queries. When users run queries in Amazon Redshift, the queries are routed to query queues. Each query queue ...
. For example, workloads that contain a mix of many small, quick queries and a few, long-running queries can be served by a pair of queues, using one with a high level of concurrency for the small, quick queries and another with a different level of concurrency for long-running queries...

A query such as SELECT * FROM large_redshift_table LIMIT 10 could take very long, as the whole table would first be UNLOADed to S3 as an intermediate result. With pushdown, the LIMIT is executed in Redshift. In queries with aggregations, pushing the aggregation down into Redshift also ...
How does Tableau run queries on Redshift? (And/or why can't Redshift display Tableau queries?) 根据上面的帖子,如果你看一下用户的屏幕截图(user717847),第二列是运行时列,我使用了tableau来准备光标,光标花费了5秒以上,但光标旁边的查询花费了不到2秒。有人能给我推荐一些优化技术来改善游标的运行时...
We have recorded the namespaces of the long-running-cluster cluster and periodic-running-cluster cluster in the previous steps, and we will use them directly in the following steps. On the periodic-running-cluster, we execute the following queries to create the data share P-to-L: ...
