Timeseries-based datastore extension

Project description


Timeseries data is streams of data that is indexed by timestamp, such as sensing data. Current default CKAN Datastore plugin only index data based on an auto-incremental integer with no support for timeseries data. Perceived that timeseries data is an important capability when working with sensor network, a new plugin that supports operations based on timestamp natively would be necessary. Thus, the purpose of this repository.

* If you are upgrading from version < 0.1.0, the schema has changed. A command has been created to upgrade the schema. Please run the following command:
paster --plugin=ckan datastore_ts -c <path to ini configuration file> upgrade-schema autogen_timestamp _autogen_timestamp


Being developed under CKAN 2.5.2

Requires iso8601:

``` pip install iso8601 ```


.. Add any additional install steps to the list below.
For example installing any non-Python dependencies or adding any required
config settings.

To install ckanext-datastore_ts:

1. Activate your CKAN virtual environment, for example::

. /usr/lib/ckan/default/bin/activate

2. Install the ckanext-datastore_ts Python package into your virtual environment::

pip install ckanext-datastore_ts

3. Add ``datastore_ts`` to the ``ckan.plugins`` setting in your CKAN
config file (by default the config file is located at

4. Restart CKAN. For example if you've deployed CKAN with Apache on Ubuntu::

sudo service apache2 reload

Config Settings
Datastore_ts uses configurations from Datastore plugin so make sure those are set. In brief:

sqlalchemy.url = postgresql://ckan_default:pass@localhost/ckan_default

ckan.datastore.write_url = postgresql://ckan_default:password@localhost/datastore_default

ckan.datastore.read_url = postgresql://datastore_default:password@localhost/datastore_default

Development Installation

To install ckanext-datastore_ts for development, activate your CKAN virtualenv and

git clone
cd ckanext-datastore_ts
python develop
pip install -r dev-requirements.txt

Running the Tests

To run the tests, do::

nosetests --nologcapture --ckan --with-pylons=test-core.ini ckanext/datastore_ts/tests/test.. .py

To run the tests and produce a coverage report, first make sure you have
coverage installed in your virtualenv (``pip install coverage``) then run::

nosetests --nologcapture --with-pylons=test.ini --with-coverage --cover-package=ckanext.datastore_ts --cover-inclusive --cover-erase --cover-tests
