LATEST MYSQL CONNECTOR FOR JAVA INSTALL
There are still several open issues that block upgrade / install with MySQL 8.0. OpenJDK JMH is a Java framework permitting micro-benchmark, taking care of things like JVM warm-up and code-optimization paths, making micro-benchmarking as simple as possible.The highest supported version of MySQL that the Percussion supports for this install/upgrade is MySQL 5.7.
Micro-benchmarking is different, you are measuring the performance of a small piece of code. To run another type of benchmark, edit the corresponding benchmark configuration file ‘ config/mariadb/sample_twitter_config.xml’ for twitter, and run it using command java -jar benchbase.jar -b twitter config/mariadb/sample_twitter_config.xml -create=true -load=true -execute=true (Down pike corresponds to when dead-locks occurs) When running the benchmark with connection strings ‘ jdbc:mariadb://localhost:3306/benchbase‘ and ‘ jdbc:mariadb://localhost:3306/benchbase?useServerPrepStmts‘ you can compare using the binary protocol versus text: Run the bench: java -jar benchbase.jar -b tpcc -c config/mariadb/sample_tpcc_config.xml -create=true -load=true -execute=trueīenchmark results will be stored in folder ‘results’, listing throughput and different value of latency for each type of transaction per second.įor this specific maximum throughput example, the file of interest is ‘ tpcc_.samples.csv’. Use the same values for the scale factor and for the number of terminals to minimize the number of possible deadlocks. Here is the corresponding change in configuration file : Jdbc:mariadb://localhost:3306/benchbase?useServerPrepStmtsįor this example, the goal will be to see the maximum throughput, setting a warmup of 60 seconds with a run of 600 seconds.

Each configuration file indicates connection information and benchmark configuration.Įxample for TPCC using mariadb driver in ‘ config/mariadb/sample_tpcc_config.xml’. Then build the package: mvn clean package -DskipTestsĬd benchbase-2021-SNAPSHOT/ Run a benchmarkĬonfiguration files are in ‘ config/mariadb/’. At the day of writing this blog post it’s MariaDB Connector/J 3.0.3: pom.xml to the latest available version. (then restart server to makes those change effective)īenchbase needs Java 17 along with a Java 17 compatible maven (>= 3.8).
LATEST MYSQL CONNECTOR FOR JAVA PASSWORD
Install MariaDB Server 10.6 with a user ‘admin’ using a password ‘password’ and a database ‘benchbase’ (default benchbase configuration).Ĭhange server configuration according to your server memory in order to have stable results (here is the configuration change for a 64G server) max_connections=500 TPC-C is mainly composed of writes while Twitter has more read commands. Although we do not claim that this is a precise representation of Twitter’s system, it still reflects its important characteristics, such as heavily skewed many-to-many relationships.

We created a synthetic workload generator that is based on an approximation of the queries/transactions needed to support the application functionalities as we observe them by using the web site, along with information derived from a data set of 200,000 tweets. In order to provide a realistic benchmark, we obtained an anonymized snapshot of the Twitter social graph from August 2009 that contains 51 million users and almost 2 billion “follows” relationships. The Twitter workload is inspired by the popular microblogging website. While the benchmark portrays the activity of a wholesale supplier, TPC-C is not limited to the activity of any particular business segment, but rather represents any industry that must manage, sell, or distribute a product or service. TPC-C is measured in transactions per minute (tpmC). The database consists of nine types of tables with a wide range of record and population sizes. TPC-C involves a mix of five concurrent transactions of different types and complexity either executed on-line or queued for deferred execution. I’ll use 2 different types of benchmark (descriptions from benchbase wiki): Benchmark frameworkĪs already mentioned, I’ll use the benchbase framework that permits to easily launch Java “real-world” benchmarks for various databases. Now, about three months later, my contribution got integrated and I decided to share a bit about how the benchbase framework can be used, but also how you can run micro-benchmarks to test or evaluate a Java connector. At some point I decided to contribute a change to the benchbase framework (formerly oltpbench) which allows the use of MariaDB Connector/J and MariaDB Server. Writing your own benchmarks is for sure not the best solution. I am working as a connectors developer for Java, Node.JS and R2DBC at MariaDB Corporation. As sysbench can only use a C connector, any influence another connector could have on the result of a benchmark is typically ignored.
There are different possibilities to benchmark MariaDB servers, with sysbench to be one often used.
