The chosen time in the query history is stored when you navigate between pages. You can monitor and control the concurrency scaling usage and cost by creating daily, weekly, or monthly usage limits and instruct Amazon Redshift to automatically take action (such as logging, alerting or disabling further usage) if those limits are reached. What is the etymology of the term space-time? Making statements based on opinion; back them up with references or personal experience. On production clusters across the fleet, we see the automated process assigning a much higher number of active statements for certain workloads, while a lower number for other types of use-cases. He specializes in building analytical solutions. Some of our partners may process your data as a part of their legitimate business interest without asking for consent. Its more efficient to load a large number of small files than one large one, and the ideal file count is a multiple of the clusters total slice count. Amazon Redshift best practices suggest using the COPY command to perform data loads of file-based data. Is there another way to do it? By default, concurrency scaling is disabled, and you can enable it for any workload management (WLM) queue to scale to a virtually unlimited number of concurrent queries, with consistently fast query performance. To prioritize your queries, use Amazon Redshift workload management (WLM). Amazon Redshift extends this ability with elastic resize and concurrency scaling. You can view the average throughput, average duration, and average queue time by different WLM queues. The Data API enables you to chain this multi-step data pipeline in a decoupled fashion. Queries with high average or minimum run times along with a number of aborted attempts should be the first queries you investigate to tune.
