Data sets and Vagrant script to provision a virtual machine for Apache Calcite development

Test data sets

This repository includes data sets and Vagrant script to provision a virtual machine with pre-installed databases.

The idea is to have an easily-available development machine for testing Apache Calcite.

Requirements

• Java
• Maven 3.0.4
• Vagrant
• Virtual Box
• 1GiB of internet for initial VM provision
• ~10GiB disk space (VirtualBox image with data consumes 3.2GiB)

Installation

Note: the databases are listening on the default ports, so you might need to pick other ports if you have MongoDB/MySQL/PostgreSQL running on your host machine. To update port forwarding, edit vm/Vagrantfile.

Alternatively, run shut.sh, which will attempt to shut down your native databases.

The step by step is as follows:

• Install Virtual Box
• Install Vagrant
• Provision a VM:

mvn install # this will download base image and install all the databases

Note: it might take 10-30 minutes depending on your machine and internet connection.

List of created databases

• Cassandra (port 9042)
• Druid (port 8082)
• H2 (h2/target folder)
• HSQLDB (hsqldb/target folder)
• MongoDB (port 27017)
• MySQL (port 3306)
• PostgreSQL (port 5432)

List of data sets

• Foodmart from Mondrian demo
• Mongo zips (as of 25 January 2015)

Using the VM

How to create a VM

A single mvn install setups and starts up the VM.

mvn install

Note: vm/target stores apt-get cache (~340MiB), so you might want avoid cleaning it.

How to drop the VM

Note: this destroys VM's data (virtual hard drive), so make sure you've backed up all your changes done in the VM.

cd vm && vagrant destroy

How to connect to VM via SSH

cd vm && vagrant ssh

How to startup and shutdown the VM

cd vm
vagrant up
vagrant halt

Accessing Cassandra in the VM

$ cd vm && vagrant ssh
vagrant@ubuntucalcite:~$ cqlsh -k twissandra `hostname -I`

Accessing Druid in the VM

Wikiticker data:

$ cd vm && vagrant ssh
vagrant@ubuntucalcite:~$ cat >query.json <<EOD
{
    "queryType" : "timeBoundary",
    "dataSource": "wikiticker"
}
EOD
vagrant@ubuntucalcite:~$ curl -X POST 'http://localhost:8082/druid/v2/?pretty' -H 'content-type: application/json'  -d @query.json
[ {
  "timestamp" : "2015-09-12T00:46:58.771Z",
    "result" : {
      "maxTime" : "2015-09-12T23:59:59.200Z",
      "minTime" : "2015-09-12T00:46:58.771Z"
  }
} ]

Foodmart data:

$ cd vm && vagrant ssh
vagrant@ubuntucalcite:~$ cat >query.json <<EOD
{
    "queryType" : "timeBoundary",
    "dataSource": "foodmart"
}
EOD
vagrant@ubuntucalcite:~$ curl -X POST 'http://localhost:8082/druid/v2/?pretty' -H 'content-type: application/json'  -d @query.json
[ {
  "timestamp" : "1997-01-01T00:00:00.000Z",

    "minTime" : "1997-01-01T00:00:00.000Z"
  }
} ]

Accessing MongoDB in the VM

Zips data:

$ cd vm && vagrant ssh
vagrant@ubuntucalcite:~$ mongo test
MongoDB shell version: 2.6.6
connecting to: test
> show collections
system.indexes
zips
> exit
bye

Foodmart data:

$ cd vm && vagrant ssh
vagrant@ubuntucalcite:~$ mongo foodmart
MongoDB shell version: 2.6.6
connecting to: foodmart
> show collections

...
> exit
bye

Accessing MySQL in the VM

$ cd vm && vagrant ssh
vagrant@ubuntucalcite:~$ mysql --user=foodmart --password=foodmart --database=foodmart
...
Server version: 5.5.40-0ubuntu0.14.04.1 (Ubuntu)
