So next we looked at the performance of the slowest queries in the clusters. They found that Redshift was about the same speed as BigQuery, but Snowflake was 2x slower. The key differences between their benchmark and ours are: They used a 10x larger data set (10TB versus 1TB) and a 2x larger Redshift cluster ($38.40/hour versus $19.20/hour). The modifications we made were small, mostly changing type names. We’ve tried to make these choices in a way that represents a typical Fivetran user, so that the results will be useful to the kind of company that uses Fivetran. Our Intermix dashboards reported a P95 latency of 1.1 seconds and a P99 latency of 34.2 seconds for the ds2.8xlarge cluster: The ra3.16xlarge cluster showed a noticeable improved overall performance: P95 latency was 36% faster at 0.7s, and P99 latency was 19% faster–a significant improvement. To start with, we looked at the overall query performance of our pipeline running on the identical data on the ds2.8xlarge cluster and the ra3.16xlarge cluster. The market is converging around two key principles: separation of compute and storage, and flat-rate pricing that can "spike" to handle intermittent workloads. We did apply column compression encodings in Redshift; Snowflake and BigQuery apply compression automatically; Presto used ORC files in HDFS, which is a compressed format, Compare Redshift, Snowflake, Presto, BigQuery. [9] We assume that real-world data warehouses are idle 50% of the time, so we multiply the base cost per second by two. The test showed that the DS2 cluster performed the deep copy on average in about 1h 58m 36s: while the RA3 cluster performed almost twice the number of copies in the same amount of time, clocking in at 1h 2m 55s on average per copy: This indicated an improvement of almost 2x in performance for queries which are heavily in network and disk I/O. The raw performance of the new GeForce RTX 3080 is fantastic in Redshift 3.0! In practice, we expect that workloads will likely always become CPU, Memory, or I/O bound before they become storage bound, making the decision to add a node (vs scale back or optimize the data product pipeline) much simpler. Feel free to get in touch directly, or join our Redshift community on Slack. Both warehouses completed his queries in 1–3 seconds, so this probably represents the “performance floor”: There is a minimum execution time for even the simplest queries. [7] BigQuery is a pure shared-resource query service, so there is no equivalent “configuration”; you simply send queries to BigQuery, and it sends you back results. Like us, they looked at their customers' actual usage data, but instead of using percentage of time idle, they looked at the number of queries per hour. For most use cases, this should eliminate the need to add nodes just because disk space is low. 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. The launch of this new node type is very significant for several reasons: 1. People at Facebook, Amazon and Uber read it every week. Periscope also compared costs, but they used a somewhat different approach to calculate cost per query. A typical Fivetran user might sync Salesforce, JIRA, Marketo, Adwords and their production Oracle database into a data warehouse. The Redshift progress is remarkable, thanks to new dc2 node types and a ⦠The source code for this benchmark is available at https://github.com/fivetran/benchmark. 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 The first thing we needed to decide when planning for the benchmark tests was what queries and datasets we should test with. Viewing our query pipeline at a high-level told us that throughput had on average improved significantly on the ra3.16xlarge cluster. The launch of the new RA3 instances addresses one of the biggest pain-points we’ve seen our customers have with administering an Amazon Redshift cluster: managing storage. This number is so high that it effectively makes storage a non-issue. Data manipulation language (DML) is the subset of SQL that you use to view, add, change, and delete data. Today we’re really excited to be writing about the launch of the new Amazon Redshift RA3 instance type. We shouldn’t be surprised that they are similar: The basic techniques for making a fast columnar data warehouse have been well-known since the C-Store paper was published in 2005. The key differences between their benchmark and ours are: They ran the same queries multiple times, which eliminated Redshift's slow compilation times. [5] Snowflake cost is based on "Standard" pricing in AWS. Update your browser to view this website correctly. You can use the best practice considerations outlined in the post to minimize the data transferred from Amazon Redshift for better performance. These warehouses all have excellent price and performance. RA3 nodes have 5x the network bandwidth compared to previous generation instances. 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. What kind of queries? Since loading data from a storage layer like S3 or DynamoDB to compute is a common workflow, we wanted to test this transfer speed. If you're evaluating data warehouses, you should demo multiple systems, and choose the one that strikes the right balance for you. In October 2016, Amazon ran a version of the TPC-DS queries on both BigQuery and Redshift. Figure 3: Star Schema. The following chart illustrates these findings. All warehouses had excellent execution speed, suitable for ad hoc, interactive querying. Having to add more CPU and Memory (i.e. The benchmark results were insightful in revealing the query execution performance of Azure SQL Data Warehouse and Redshift and some of the differentiators in the two products. Gigaom's cloud data warehouse performance benchmark In April 2019, Gigaom ran a version of the TPC-DS queries on BigQuery, Redshift, Snowflake and Azure SQL Data Warehouse (Azure Synapse). We generated the TPC-DS [1] data set at 1TB scale. In our experience, I/O is most often the cause of slow query performance. Every compute cluster sees the same data, and compute clusters can be created and removed in seconds. Redshift has node-based architecture where you can configure the size and number of nodes to meet your needs. Please note these results are as of July 2018. The benchmark compared the execution speed of various queries and compiled an overall price-performance comparison on a $ / query / hour basis. The time differences are small; nobody should choose a warehouse on the basis of 7 seconds versus 5 seconds in one benchmark. Redshift is a cloud data warehouse that achieves efficient storage and optimum query performance through a combination of massively parallel processing, columnar data storage, and targeted data compression encoding schemes. Note: $/Yr for Amazon Redshift is based on the 1-year Reserved Instance price. For example, they used a huge Redshift cluster — did they allocate all memory to a single user to make this benchmark complete super-fast, even though that’s not a realistic configuration? Redshift RA3 brings Redshift closer to the user experience of Snowflake by separating compute from storage. Amazon Redshift. And then there’s also Amazon Redshift Spectrum, to join data in your RA3 instance with data in S3 as part of your data lake architecture, to independently scale storage and compute. Happy query federating! NOTE: You canât always expect an 8 times performance increase using these Amazon Redshift performance tuning tips with Redshift Optimization. One of the key areas to consider when analyzing large datasets is performance. Our primary Redshift data product pipeline consists of batch ETL jobs that reduce raw data loaded from S3 (aka “ELT”). The most important differences between warehouses are the qualitative differences caused by their design choices: Some warehouses emphasize tunability, others ease of use. Every Monday morning we'll send you a roundup of the best content from intermix.io and around the web. We used v0. There are many details not specified in Amazon’s blog post. 329 of the Starburst distribution of Presto. This change decreased the query response times by approximately 80%. 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. Their queries were much simpler than our TPC-DS queries. You can find the details below, but letâs start with the bottom line: Redshift Spectrumâs Performance. To accelerate analytics, Fivetran enables in-warehouse transformations and delivers source-specific analytics templates. The test completed in November showed that Amazon Redshift delivers up to three times better price performance out-of-the-box than other cloud data warehouses. If you use a higher tier like "Enterprise" or "Business Critical," your cost would be 1.5x or 2x higher. We copied a large dataset into the ds2.8xlarge, paused all loads so the cluster data would remain fixed, and then snapshotted that cluster and restored it to a 2-node ra3.16xlarge cluster. [â¦] So in the end, the best way to evaluate performance is with real-world code running on real-world data. 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. As always, we’d love your feedback on our results and to hear your experiences with the new RA3 node type. See all issues. Even though we used TPC-DS data and queries, this benchmark is not an official TPC-DS benchmark, because we only used one scale, we modified the queries slightly, and we didn’t tune the data warehouses or generate alternative versions of the queries. Conclusion With the right configuration, combined with Amazon Redshiftâs low pricing, your cluster will run faster and at lower cost than any other warehouse out there, including Snowflake and BigQuery. The difference was marginal for single-user tests. Compression conserves storage space and reduces the size of data that is read from storage, which reduces the amount of disk I/O and therefore improves query performance. A "spiky" workload that contains periodic large queries interspersed with long periods of idleness or lower utilization will be much cheaper in on-demand mode. This result is pretty exciting: For roughly the same price as a larger ds2.8xlarge cluster, we can get a significant boost in data product pipeline performance, while getting twice the storage capacity. Here are some more best practices you can implement for further performance improvement: Use SORT keys on columns that are often used in WHERE clause filters. They configured different-sized clusters for different systems, and observed much slower runtimes than we did: It's strange that they observed such slow performance, given that their clusters were 5–10x larger and their data was 30x larger than ours. Using the previously mentioned Amazon Redshift changes can improve query performance and improve cost and resource efficiency. Redshift at most exceeds Shard-Query performance by 3x. We set up each warehouse in a small and large configuration for the 100GB and 1TB scales: These data warehouses each offer advanced features like sort keys, clustering keys and date partitioning. If you're interested in downloading this report, you can do so here. Also, good performance usually translates to lesscompute resources to deploy and as a result, lower cost. It would be great if AWS would publish the code necessary to reproduce their benchmark, so we could evaluate how realistic it is. 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 ⦠[4] To calculate a cost per query, we assumed each warehouse was in use 50% of the time. We ran 99 TPC-DS queries [3] in Feb.-Sept. of 2020. [1] TPC-DS is an industry-standard benchmarking meant for data warehouses. It is faster than anything in the RTX 20 Series was, and 85% faster than the RTX 2080 Super for the same price. Snowflake has several pricing tiers associated with different features; our calculations are based on the cheapest tier, "Standard." Presto is open-source, unlike the other commercial systems in this benchmark, which is important to some users. With 64Tb of storage per node, this cluster type effectively separates compute from storage. 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. For this test, we used a 244 Gb test table consisting of 3.8 billion rows which was distributed fairly evenly using a DISTKEY. We followed best practices for loading data into Redshift, such as using a manifest file to define the data files being loaded and defining a distribution style on the target table. To calculate cost, we multiplied the runtime by the cost per second of the configuration [8]. Redshift and BigQuery have both evolved their user experience to be more similar to Snowflake. Today weâre really excited to be writing about the launch of the new Amazon Redshift RA3 instance type. We ran the SQL queries in Redshift Spectrum on each version of the same dataset. In this post, we’re going to explore the performance of the new ra3.16xlarge instance type and compare it to the next largest instance type, the ds2.8xlarge. These queries are complex: They have lots of joins, aggregations and subqueries. 2. These data sources aren’t that large: A typical source will contain tens to hundreds of gigabytes. The nodes also include a new type block-level caching that prioritizes frequently-accessed data based on query access patterns at the block level. Azure SQL DW outperformed Redshift in 56 of the 66 queries ran. A "steady" workload that utilizes your compute capacity 24/7 will be much cheaper in flat-rate mode. To calculate cost-per-query for Snowflake and Redshift, we made an assumption about how much time a typical warehouse spends idle. For this test, we ran all 99 queries from the TPC-DS benchmark against a 3 TB data set. However, what we felt was lacking was a very clear and comprehensive comparison between what are arguably the two most important factors in a querying service: costs and performance. Today we are armed with a Redshift 3.0 license and will be using the built-in benchmark scene in Redshift v3.0.22 to test nearly all of the current GeForce GTX and RTX offerings from NVIDIA. To reduce query execution time and improve system performance, Amazon Redshift caches the results of certain types of queries in memory on the leader node. To know how we did it in minutes instead of days â click here! To compare relative I/O performance, we looked at the execution time of a deep copy of a large table to a destination table that uses a different distkey. 23rd September 2020 â Updated with Fivetran data warehouse performance comparison, Redshift Geospatial updates. On RA3 clusters, adding and removing nodes will typically be done only when more computing power is needed (CPU/Memory/IO). BigQuery charges per-query, so we are showing the actual costs billed by Google Cloud. We ran each query only once, to prevent the warehouse from caching previous results. On-demand mode can be much more expensive, or much cheaper, depending on the nature of your workload. The problem with doing a benchmark with “easy” queries is that every warehouse is going to do pretty well on this test; it doesn’t really matter if Snowflake does an easy query fast and Redshift does an easy query really, really fast. Amazon Redshift outperformed BigQuery on 18 of 22 TPC-H benchmark queries by an average of 3.6X. Mark Litwintshik benchmarked BigQuery in April 2016 and Redshift in June 2016. Snowflake is a nearly serverless experience: The user only configures the size and number of compute clusters. It is important, when providing performance data, to use queries derived from industry standard benchmarks such as TPC-DS, not synthetic workloads skewed to show cherry-picked queries. We used BigQuery standard-SQL, not legacy-SQL. Learn more about data integration that keeps up with change at fivetran.com, or start a free trial at fivetran.com/signup. nodes) just to handle the storage of more data, resulting in wasted resources; Having to go through the time-consuming process of determining which large tables aren’t actually being used by your data products so you can remove these “cold” tables; Having to run a cluster that is larger than necessary just to handle the temporary intermediate storage required by a few very large SQL queries. We then started our data product pipeline and fired up our intermix dashboard to quantitatively monitor performance and characteristics of the two clusters. There are plenty of good feature-by-feature comparison of BigQuery and Athena out there (e.g. When queries are well written for federation, the performance penalties are negligible, as observed in the TPC-DS benchmark queries in this post. 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 In April 2019, Gigaom ran a version of the TPC-DS queries on BigQuery, Redshift, Snowflake and Azure SQL Data Warehouse (Azure Synapse). While seemingly straightforward, dealing with storage in Redshift causes several headaches: We’ve seen variations of these problems over and over with our customers, and expect to see this new RA3 instance type greatly reduce or eliminate the need to scale Redshift clusters just to add storage. This is shown in the following chart. Benchmarks are great to get a rough sense of how a system might perform in the real-world, but all benchmarks have their limitations. If you expect to use "Enterprise" or "Business Critical" for your workload, your cost will be 1.5x or 2x higher. Fivetran is a data pipeline that syncs data from apps, databases and file stores into our customers’ data warehouses. Compared to Markâs benchmark years ago, the 2020 versions of both ClickHouse and Redshift show much better performance. We chose not to use any of these features in this benchmark [7]. What matters is whether you can do the hard queries fast enough. Combined with a 25% increase in VRAM, that massive ⦠In real-world scenarios, single-user test results do not provide much value. Note: We used a Cloud DW benchmark ⦠It consists of a dataset of 8 tables and 22 queries that ar⦠How much? One of the things we were particularly interested in benchmarking is the advertised benefits of improved I/O, both in terms of network and storage. Overall, the benchmark results were insightful in revealing query execution performance and some of the differentiators for Avalanche, Synapse, Snowflake, Amazon Redshift, and Google BigQuery. The launch of this new node type is very significant for several reasons: This is the first feature where Amazon Redshift can credibly claim “separation of storage and compute”. 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. Also in October 2016, Periscope Data compared Redshift, Snowflake and BigQuery using three variations of an hourly aggregation query that joined a 1-billion row fact table to a small dimension table. 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! We can place them along a spectrum: On the "self-hosted" end of the spectrum is Presto, where the user is responsible for provisioning servers and detailed configuration of the Presto cluster. We used Redshiftâs COPY command to read and load data files from S3, which had been unloaded from a source table with 3.8 billion rows. The ETL transformations start with around 50 primary tables, and go through several transformations to produce around 30 downstream tables. These data warehouses undoubtedly use the standard performance tricks: columnar storage, cost-based query planning, pipelined execution and just-in-time compilation. These results are based on a specific benchmark test and wonât reflect your actual database design, size, and queries. Our latest benchmark compares price, performance and differentiated features for BigQuery, Presto, Redshift and Snowflake. On RA3 clusters, adding and removing nodes will typically be done only when more computing power is needed (CPU/Memory/IO). Running the query on 1-minute Parquet improved performance by 92.43% compared to raw JSON Most queries are close in performance for significantly less cost. When considering the relative performance for entire datasets, Redshift outperforms BigQuery by 2X. The price/performance argument for Shard-Query is very compelling. Amazon Redshift Spectrum Nodes execute queries against an Amazon S3 data lake. Tuning query performance Amazon Redshift uses queries based on structured query language (SQL) to interact with data and objects in the system. We’ve also received confirmation from AWS that they will be launching another RA3 instance type, ra3.4xlarge, so you’ll be able to get all the benefits of this node type even if your workload doesn’t require quite as much horsepower. here, here and here), and we donât have much to add to that discussion. 3 Things to Avoid When Setting Up an Amazon Redshift Cluster. The slowest task on both clusters in this time range was get_samples-query, which is a fairly complex SQL transformation that joins, processes, and aggregates 11 tables. On the 4-node ds2.8xlarge, this task took on average 38 minutes and 51 seconds: This same task running on the 2-node ra3.16xlarge took on average 32 minutes and 15 seconds, an 18% improvement! The performance boost of this new node type (a big part of which comes from improvements in network and storage I/O) gives RA3 a significantly better bang-for-the-buck compared to previous generation clusters. The question we get asked most often is, “What data warehouse should I choose?” In order to better answer this question, we’ve performed a benchmark comparing the speed and cost of four of the most popular data warehouses: Benchmarks are all about making choices: What kind of data will I use? Benchmarks from vendors that claim their own product is the best should be taken with a grain of salt. Optimizing Query Performance Extracting optimal querying performance mainly can be attributed to bringing the physical layout of data in the cluster in congruence with your query patterns. While the DS2 cluster averaged 2h 9m 47s to COPY data from S3 to Redshift, the RS3 cluster performed the same operation at an average of 1h 8m 21s: The test demonstrated that improved network I/O on the ra3.16xlarge cluster loaded identical data nearly 2x faster than the ds2.8xlarge cluster. Comparing Amazon Redshift releases over the past few months, we observed that Amazon Redshift is now 3.5x faster versus six months ago, running all 99 queries derived from the TPC-DS benchmark. [2] This is a small scale by the standards of data warehouses, but most Fivetran users are interested in data sources like Salesforce or MySQL, which have complex schemas but modest size. Learn about building platforms with our SF Data Weekly newsletter, read by over 6,000 people! While our pipeline also includes some external jobs that occur in platforms outside of Redshift, weâve excluded the performance of those jobs from this post, since it is not relevant to the ra3.16xlarge to ds2.8xlarge comparison. 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. They tuned the warehouse using sort and dist keys, whereas we did not. 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.
