Introduction to Database Benchmarking with Benchmark Factory

Scenarios:Assessing new database systems can be done by running TPC benchmarks. These benchmarks help evaluate the performance and scalability of a new DBMS. They also allow for comparison with other options available in the market.Comparing different configurations: TPC benchmarks help assess how hardware and software changes affect database performance. This helps in optimizing the system for specific workloads.Capacity planning includes running TPC benchmarks with varying data sizes and concurrent users. This helps determine the hardware and software resources required for future growth and performance.Benchmarking NoSQL DatabasesResearchers created TPC benchmarks for traditional databases, but they can also be used to assess the speed of NoSQL databases. NoSQL databases are diverse and serve different purposes, so there is no one-size-fits-all benchmark for all systems. Some NoSQL vendors provide their own benchmarks or adapt existing TPC benchmarks to suit their specific database model.Examples of TPC Benchmark ResultsLet’s look at some examples of TPC benchmark results for both non-clustered and clustered databases:Non-Clustered Database ExampleConsider a TPC-C benchmark run on a single-node database server with the following configuration:Hardware: 2x Intel Xeon E5-2699 v4 @ 2.20GHz, 512GB RAMDatabase: PostgreSQL 13Dataset: 5,000 warehousesThe benchmark results show:Transactions per minute (tpmC): 1,500,000Price/performance ($/tpmC): $0.50This shows that the database system can handle 1.5 million transactions every minute for $0.50 each.Clustered Database ExampleNow let’s consider a TPC-H benchmark run on a clustered database with the following setup:Hardware: 8x nodes, each with 2x Intel Xeon E5-2699 v4 @ 2.20GHz, 512GB RAMDatabase: Greenplum 6.0Dataset: 10 TBThe benchmark results show:Power@Size (QphH@10TB): 1,000,000Price/performance ($/QphH@10TB): $50The grouped database system can handle 1 million queries in an hour on a 10 TB dataset. It costs $50 per query per hour in terms of performance.ConclusionTPC benchmarks provide a standardized and reliable way to evaluate the performance and scalability of database management systems. Organizations can improve decision-making when selecting BenchBaseBenchBase (formerly OLTPBench) is a Multi-DBMS SQL Benchmarking Framework via JDBC.Table of ContentsQuickstartDescriptionUsage GuideContributingKnown IssuesCreditsCiting This RepositoryQuickstartTo clone and build BenchBase using the postgres profile,git clone --depth 1 benchbase./mvnw clean package -P postgresThis produces artifacts in the target folder, which can be extracted,cd targettar xvzf benchbase-postgres.tgzcd benchbase-postgresInside this folder, you can run BenchBase. For example, to execute the tpcc benchmark,java -jar benchbase.jar -b tpcc -c config/postgres/sample_tpcc_config.xml --create=true --load=true --execute=trueA full list of options can be displayed,java -jar benchbase.jar -hDescriptionBenchmarking is incredibly useful, yet endlessly painful. This benchmark suite is the result of a group ofPhDs/post-docs/professors getting together and combining their workloads/frameworks/experiences/efforts. We hope thiswill save other people's time, and will provide an extensible platform, that can be grown in an open-source fashion.BenchBase is a multi-threaded load generator. The framework is designed to be able to produce variable rate,variable mixture load against any JDBC-enabled relational database. The framework also provides data collectionfeatures, e.g., per-transaction-type latency and throughput logs.The BenchBase framework has the following benchmarks:AuctionMarkCH-benCHmarkEpinions.comhyadapt -- pending configuration filesNoOpOT-MetricsResource StresserSEATSSIBenchSmallBankTATPTPC-CTPC-HTPC-DS -- pending configuration filesTwitterVoterWikipediaYCSBThis framework is design to allow for easy extension. We provide stub code that a contributor can use to include a newbenchmark, leveraging all the system features (logging, controlled speed, controlled mixture, etc.)Usage GuideHow to BuildRun the following command to build the distribution for a given database specified as the profile name (-P). The following profiles are currently supported: postgres, mysql, mariadb, sqlite, cockroachdb, phoenix, and spanner.">./mvnw clean package -P profile name>The following files will be placed in the ./target folder:benchbase-.tgzbenchbase-.zipHow to RunOnce you build and unpack the distribution, you can run benchbase just like any other executable jar. The following examples assume you are running from the root of the expanded .zip or .tgz distribution. If you attempt to run benchbase outside of the distribution structure you may encounter a variety of errors including java.lang.NoClassDefFoundError.To bring up help contents:java -jar benchbase.jar -hTo execute the tpcc benchmark:java -jar benchbase.jar -b tpcc -c config/postgres/sample_tpcc_config.xml --create=true --load=true --execute=trueFor composite benchmarks like chbenchmark, which require multiple schemas to be created and loaded, you can provide a comma separated list:java -jar benchbase.jar -b tpcc,chbenchmark -c config/postgres/sample_chbenchmark_config.xml --create=true --load=true --execute=trueThe following options are provided: [required] Benchmark class.

IntroductionWhen comparing different database management systems, it’s important to use a consistent and trustworthy method to evaluate their performance. TPC benchmark helps evaluate how well different database systems perform and grow in size. This article will cover the basics of TPC benchmarks. It will explain why they are important and how they can help organizations choose a DBMS wisely.What is the Transaction Processing Performance Council (TPC)?The Transaction Processing Performance Council (TPC) is a non-profit organization founded in 1988. Our goal is to create standards for transaction processing and database benchmarks, and provide accurate performance data to the industry. The TPC consists of major computer and database vendors, leading industry experts, and academic representatives who collaborate to develop industry-standard benchmarks.Understanding Database Management System BenchmarksA DBMS benchmark is a test to measure how well a database management system performs under certain workload conditions. These benchmarks mimic real-life situations and give measurements like transactions per second, response time, and price/performance ratio. By running these benchmarks, organizations can compare different database systems and make informed decisions based on their specific requirements.Types of TPC BenchmarksThe TPC offers several benchmarks tailored to different workload scenarios:TPC-C: This benchmark simulates an online transaction processing (OLTP) environment, such as order entry and processing systems. It calculates how many orders are completed in a minute and gives data on transactions per minute and cost efficiency.TPC-H is for decision support systems. It tests how well complex queries perform with big data. It measures the power and throughput of a system, providing metrics like queries per hour (QphH) and price/performance ($/QphH).TPC-DS is a benchmark similar to TPC-H. It models aspects of a decision support system, including queries and data maintenance. It provides metrics such as queries per hour (QphDS) and price/performance ($/QphDS).When to Use TPC BenchmarksTPC benchmarks are valuable tools in various.

Benchmark Factory (formerly Benchmark Factory for Databases)

Is shared by many processes and users as a temporary working area. The default configuration is suitable for most workloads, but the installation process can help guide your configuration, as described in the Microsoft TempDB Database documentation If the server is dedicated to the MS SQL Server workload, then use either the default dynamic memory management model or follow Microsoft SQL documentation guidelines to manually configure memory options if you need more granular controlFigure 1. Lenovo ThinkSystem SR665 V3 Performance Testing Details and Results HammerDB ConfigurationHammerDB is an open-source database transactional and analytics load testing/benchmarking tool for databases. The OLTP workload is based on TPC® Benchmark C (TPC-C), and the Analytics workload is based on TPC Benchmark H (TPC-H). The HammerDB OLTP and Analytics workloads are open source workloads derived from the TPC-C Benchmark Standard and the TPC-H Benchmark Standard, respectively, and as such are not comparable to published TPC-C or TPC-H results, as the results do not comply with the TPC-C and TPC-H Benchmark Standards.

Several distributed database vendors have added support for the PostgreSQL protocol as a convenient way to gain access to the PostgreSQL ecosystem. Others (like us) have built a distributed database on top of PostgreSQL itself. For the Citus database team, distributed PostgreSQL is primarily about achieving high performance at scale. The unique thing about Citus, the technology powering Azure Cosmos DB for PostgreSQL, is that it is fully implemented as an open-source extension to PostgreSQL. It also leans entirely on PostgreSQL for storage, indexing, low-level query planning and execution, and various performance features. As such, Citus inherits the performance characteristics of a single PostgreSQL server but applies them at scale. That all sounds good in theory, but to see whether this holds up in practice, you need benchmark numbers. We therefore asked GigaOM to run performance benchmarks comparing Azure Cosmos DB for PostgreSQL to other distributed implementations. GigaOM compared the transaction performance and price-performance of these popular managed services of distributed PostgreSQL, using the HammerDB benchmark software: Keep reading My main advice when running performance benchmarks for Postgres is: "Automate it!" If you're measuring database performance, you are likely going to have to run the same benchmark over and over again. Either because you want a slightly different configuration, or because you realized you used some wrong settings, or maybe some other reason. By automating the way you're running performance benchmarks, you won't be too annoyed when this happens, because re-running the benchmarks
