MicroStream BookStore Performance Demo

MicroStream BookStore Performance Demo

With this demo the superior performance of MicroStream and the Java VM compared to JPA with a connected database is visualized. It is a Spring Boot application with a Vaadin frontend. Per default Postgres is used, but you can change the application's setup, to use any other database.

Setup

• First you need to setup a Postgres database. Then the connection settings must be adjusted in the application.properties file accordingly.

• Start the program via its main class: one.microstream.demo.bookstore.Application

• At the first start a new MicroStream database is generated with random data. Depending on the setting bookstoredemo.initialDataAmount more or less data is produced.

• Then the data has to be migrated to the connected JPA database

  • If bookstoredemo.jpaDataMigrationStrategy is batch_insert (default), the data will be automatically migrated.

  • If it is set to sql_file the generated data will be written into a SQL file, which must then be imported into the JPA database. It can be found in the configured data directory bookstoredemo.dataDir, default is [userhome]/microstream-bookstoredemo. Please note, that this is by far the faster way, but the generated inserts are optimized for Postgres and probably won't work with a different database.

Here you can see the entity relationship diagram of the generated database:

Usage

After the application has started, open the client interface at: http://localhost.
