Installing HOTMapper and dependencies

In this section we'll look at how to get MonetDB working with hotmapper.

Important:

The MonetDB Apr2019 (11.33.3) version should be avoided, because it has a bug when inserting into a table with multiple constraints. It's already fixed in their nightly build so you should be fine using any superior version or the August2018 one.

Getting HOTMapper

To get the lastest version of HOTMapper simple clone the git repository.

git clone git@gitlab.c3sl.ufpr.br:tools/hotmapper.git

Getting MonetDB

You can get your MonetDB installation following their instructions.

Be sure to create and start your farm, if you didn't already, using:

$ monetdbd create /path/to/my-dbfarm
$ monetdbd start /path/to/my-dbfarm

If you didn't set a systemctl command for your farm remember to start it every time you reboot your OS.

To create a new database, and remove it from maintenance mode(to avoid a very high memory usage):

$ monetdb create hotmapper-demo
$ monetdb release hotmapper-demo

Getting HOTMapper dependencies

Let's create a new virtual environment and install the requirements.

Be sure that you have installed pip3 and python 3.5+.

Install python3-venv, if you don't have it, using the command bellow.

$ sudo apt-get install python3-venv

Inside the hotmapper folder execute the following commands:

$ python3 -m venv env
$ source env/bin/activate
$ pip install -r requirements.txt
