Viewing our query pipeline at a high-level told us that throughput had on average improved significantly on the ra3.16xlarge cluster. 3 Things to Avoid When Setting Up an Amazon Redshift Cluster. The Redshift progress is remarkable, thanks to new dc2 node types and a … To compare the 2-node ra3.16xlarge and 4-node ds2.8xlarge clusters, we setup our internal data pipeline for each cluster. For this test, we used a 244 Gb test table consisting of 3.8 billion rows which was distributed fairly evenly using a DISTKEY. Fivetran improves the accuracy of data-driven decisions by continuously synchronizing data from source applications to any destination, allowing analysts to work with the freshest possible data. On paper, the ra3.16xlarge nodes are around 1.5 times larger than ds2.8xlarge nodes in terms of CPU and Memory, 2.5 times larger in terms of I/O performance, and 4 times larger in terms of storage capacity: A reported improvement for the RA3 instance type is a bigger pipe for moving data into and out of Redshift. Every Monday morning we'll send you a roundup of the best content from intermix.io and around the web. BigQuery on demand is a pure serverless model, where the user submits queries one at a time and pays per query. One of the ways we ensure that we provide the best value for customers is to measure the performance of Amazon Redshift and other cloud data warehouses regularly using queries derived from industry-standard benchmarks such as TPC-DS. We created an empty target table which differed from the source table in that it used DISTSTYLE of EVEN, and then did an INSERT INTO … SELECT * from the source table into the target table several times. 2. And because a ra3.16xlarge cluster must have at least two nodes, the minimum cluster size is a whopping 128TB. To make it easy to track the performance of the SQL queries, we annotated each query with the task benchmark-deep-copy and then used the Intermix dashboard to view the performance on each cluster for all SQL queries in that task. On-demand mode can be much more expensive, or much cheaper, depending on the nature of your workload. We ran 99 TPC-DS queries [3] in Feb.-Sept. of 2020. Amazon Redshift customers span all industries and sizes, from startups to Fortune 500 companies, and we work to deliver the best price performance for any use case. Since the ra3.16xlarge is significantly larger than the ds2.8xlarge, we’re going to compare a 2-node ra3.16xlarge cluster against a 4-node ds2.8xlarge cluster to see how it stacks up. Overall, the performance advantage was 1.67 times faster. The key differences between their benchmark and ours are: They ran the same queries multiple times, which eliminated Redshift's slow compilation times. Moving on to the next-slowest-query in our pipeline, we saw average query execution improve from 2 minutes on the ds2.8xlarge down to 1 minute and 20 seconds on the ra3.16xlarge–a 33% improvement! You can use the best practice considerations outlined in the post to minimize the data transferred from Amazon Redshift for better performance. With 64Tb of storage per node, this cluster type effectively separates compute from storage. Query Performance. The difference was marginal for single-user tests. Periscope also compared costs, but they used a somewhat different approach to calculate cost per query. We ran each query only once, to prevent the warehouse from caching previous results. This should force Redshift to redistribute the data between the nodes over the network, as well as exercise the disk I/O for reads and writes. The source code for this benchmark is available at https://github.com/fivetran/benchmark. Having to add more CPU and Memory (i.e. RA3 no… NVIDIA GPU Performance In Arnold, Redshift, Octane, V-Ray & Dimension by Rob Williams on January 5, 2020 in Graphics & Displays , Software We recently explored GPU performance in RealityCapture and KeyShot, two applications that share the trait of requiring NVIDIA GPUs to run. There are two major sets of experiments we tested on Amazon’s Redshift: speed-ups and scale-ups. Note: $/Yr for Amazon Redshift is based on the 1-year Reserved Instance price. [6] Presto is an open-source query engine, so it isn't really comparable to the commercial data warehouses in this benchmark. We ran the SQL queries in Redshift Spectrum on each version of the same dataset. Over the last two years, the major cloud data warehouses have been in a near-tie for performance. When analyzing the query plans, we noticed that the queries no longer required any data redistributions, because data in the fact table and metadata_structure was co-located with the distribution key and the rest of the tables were using the ALL distribution style; and because the fact … Using the rightdata analysis tool can mean the difference between waiting for a few seconds, or (annoyingly)having to wait many minutes for a result. Redshift and BigQuery have both evolved their user experience to be more similar to Snowflake. If you're evaluating data warehouses, you should demo multiple systems, and choose the one that strikes the right balance for you. You can find the details below, but let’s start with the bottom line: Redshift Spectrum’s Performance. However, typical Fivetran users run all kinds of unpredictable queries on their warehouses, so there will always be a lot of queries that don’t benefit from tuning. In October 2016, Amazon ran a version of the TPC-DS queries on both BigQuery and Redshift. Run queries derived from TPC-H to test the performance; For best performance numbers, always do multiple runs of the query and ignore the first (cold) run; You can always do a explain plan to make sure that you get the best expected plan Benchmarks from vendors that claim their own product is the best should be taken with a grain of salt. In real-world scenarios, single-user test results do not provide much value. They found that Redshift was about the same speed as BigQuery, but Snowflake was 2x slower.
