Blacksmith test

最近使用Blacksmith 對各類K,V數據庫作了一些測試，從中瞭解了一些各類數據庫的設計方式，比較各類數據庫的性能

BlaskSmith是咱們本身的產品，詳細的產品信息能夠在github上看到 https://github.com/lawrencewu/blacksmith

測試的數據庫包括 bigmap， sessdb(https://github.com/lawrencewu/sessdb), leveldb(https://github.com/dain/leveldb)

berkeleyDB(http://www.oracle.com/technetwork/database/database-technologies/berkeleydb/downloads/index.html)  java edition

mapdb http://www.mapdb.org

如下的內容講述如何使用Blacksmith對各類k,v數據庫作測試

 

 準備工做

1. download the blacksmith from github, it's a maven project

   the download address is https://github.com/lawrencewu/blacksmith

2. Install

$ unzip blacksmith.zip
$ cd blacksmith
$ mvn clean install

3. run the test

$ target/distribution/BlackSmith-1.0.0
$ bin/local.sh

 4. run the high level test by trying

$ target/distribution/BlackSmith-1.0.0
$ bin/local.sh -c conf/local-benchmark-high-contention.xml

5. run the low level test by trying

$ target/distribution/BlackSmith-1.0.0
$ bin/local.sh -c conf/local-benchmark-low-contention.xml

6. after the above operation, we can get the report under the  reports folder.

  i.e. the comparison between different databases.

       

How to add a plugin:

　　The tool's only useful when you add another plugin to test other k,v databases. This senario shows how to add a plugin

　　Step1:

　　　　Add a folder under the plugins folder, named it whatever you like  e.g.  test

     Step2:

          Implements the  DBWrapper interface

    Step3:

          Replace the property file with your wrapper

    step4:

         config the project pom.xml file， add this plugin to the  module section, and copy files to the destination location

 

you can try different test schema by changing the params in the StressTest tag.

Params specification:

　　1. numRequests 

           Total number of operation to be made against cache wrapper: reads + writes. Default is 50000.

      2. numEntries

　　　　Number of keys on which all the GETs and PUTs are performed. Default is 100.
