gludb 0.2.0

Generalized Learning Utilities Database Library

For more GLU, see also SuperGLU

GLUDB provides a simple way to read/write data to some popular datastores like Amazon’s DynamoDB and Google Cloud Datastore. We provide:

• A simple abstraction layer for annotating classes that need serialization

• Support for versioning by automatically storing change history with the data

• Automated “indexing”, which includes querying on the value of indexes

• Automated, configurable backup to Amazon’s S3 (and Glacier depending on how you configure the S3 buckets)

We support Python 2 (2.7 and greater) and 3 (3.4 and greater). The data stores supported are:

• sqlite

• DynamoDB

• Google Cloud Datastore

• MongoDB

• PostgreSQL (version 9.5 and greater)

Installing

You can install from PyPI using pip:

pip install gludb

You will also need to install any dependencies you need based on the functionality you want to use:

• DynamoDB Backend - boto

• Google Cloud Datastore - googledatastore

• MongoDB - pymongo

• Backups - boto

setup.py includes these dependencies so that you can install them all at the same time (assuming a decently recent version of pip). As an example, you could install gludb and the dependencies needed for DynamoDB and backup support into a virtualenv using Python 3 like this:

user@host:~$ virtualenv -p python3 env
user@host:~$ . env/bin/activate
user@host:~$ pip install --upgrade pip wheel
user@host:~$ pip install gludb[dynamodb,backups]
