BigTempo is a powerful and scalable programming model, originally crafted for temporal data processment / analysis.

This is a Python package created to help you build complex hierarchies of processments, each refered as a datasource. The package was originally conceived to handle temporal data and it is typically used as a colleague of pandas - dealing with time series and dataframes - but it is flexible and can easily be extended to support other data models. It handles dependency resolution, provides a tagging system that enables querying operations over datasource sets, and much more.
There are other software packages that focus on lower level aspects of data processing, like pandas, numpy, sympy, theano. This is not a framework to replace these. Instead, it aims to support many of these tools, helping you to stitch many processments together. It provides a decoupled programming model that was built with scalability support in its heart and it takes care of a lot of the workflow management so that you can focus on the data itself.
Bigtempo aims to provide support an wide range of applications - including artificial intelligence systems - working in data pull fashion. Its philosophy is to lazyload things as possible: analysis are retrieved from cache if available, processed otherwise. A datasource serves data through processors that can be used by other datasources (or by you directly) and processors are made to be executed in a distributed fashion, if that is desired.
Keep in mind that the package - although performatic - is in Alpha Stage and, as so, most of its caching and distributed processing capabilities are still in the owen.

To install, simply:
$ pip install bigtempo
Or, if you absolutely must:
$ easy_install bigtempo
Both the installation methods above should take care of dependencies on its own, automatically.
The pandas library is the only direct dependency the package has in order to be executed. You should visit its page to find out what it depends on. For best results, we recommend installing optional packages as well.
If you want to run the package tests, or enjoy its testing facilities, you’ll need:
mockito >= 0.5.1
In order to run the tests using the command contained in the bin directory, also install:
nose >= 1.3.0
coverage >= 3.6
pep8 >= 1.4.5
Installing from source
To install bigtempo from source you need:
Clone the git repository:
$ git clone https://github.com/rhlobo/bigtempo.git
Get into the project directory:
$ cd bigtempo
Install dependencies (if you are not using virtualenv, it may need super user privileges):
$ pip install -r requirements.txt
$ python setup.py install
Alternatively, you can use pip if you want all the dependencies pulled in automatically (the optional -e option is for installing it in development mode):
$ pip install -e .
Build in process pools
Integration with celery
Integration with Apache ZooKeeper and ZeroMQ
Smart temporal data caching
