Timebase Tutorial

About these samples

Timebase performance test utility. It uses external data file to generate sample data and then run QQL on test and measure estimated time

Requirements

  • Java 11

How to build

./gradlew shadowJar

it will create a "fat" jar for the application located in build/libs/timebase-performance-1.0.1-all.jar

How to run

  1. Start TimeBase Server on port 8011

  2. java -cp ./build/libs/timebase-performance-1.0.1-all.jar com.epam.deltix.samples.timebase.performance.Runner -dataFile order_book_depth-ce.qsmsg.gz -stream order-book-tests -spaces 5 -qqlFile qql.txt

This execution will use data file order_book_depth-ce.qsmsg.gz to create sample stream order-book-tests contains 5 spaces with 40m records for the different symbols.
After it run all queries (each line) defined in qql.txt file.

Program Arguments

Usage:
      -timebase dxtick://localhost:8011 -dataFile order_book_depth-ce.qsmsg.gz -stream order_book_depth -spaces 10 -qqlFile qql.txt
Parameters Definition:
      -timebase <value>  - timebase connection url
      -dataFile <path>   - path to qsmsg file contains sample data. if file is not provided, then only tests will be run
      -stream <name>     - stream to create. default is 'order-book-test'
      -spaces <value>    - number of spaces in the stream to create. default = 10
      -qqlFile <path>    - file contains qql queries to test performance
