A Pythonic interface for Amazon’s DynamoDB that supports Python 2 and 3.
DynamoDB is a great NoSQL service provided by Amazon, but the API is verbose. PynamoDB presents you with a simple, elegant API.
See documentation at http://pynamodb.readthedocs.org/
Basic Usage
Create a model that describes your DynamoDB table.
from pynamodb.models import Model
from pynamodb.attributes import UnicodeAttribute
class UserModel(Model):
"""
A DynamoDB User
"""
table_name = 'dynamodb-user'
email = UnicodeAttribute(null=True)
first_name = UnicodeAttribute(range_key=True)
last_name = UnicodeAttribute(hash_key=True)Now, search your table for all users with a last name of ‘Smith’ and whose first name begins with ‘J’:
for user in UserModel.query('Smith', first_name__begins_with='J'):
print(user.first_name)Create a new user:
user = UserModel('John', 'Denver')
user.save()Advanced Usage
Wan’t to use indexes? No problem:
from pynamodb.models import Model
from pynamodb.indexes import GlobalSecondaryIndex, AllProjection
from pynamodb.attributes import NumberAttribute, UnicodeAttribute
class ViewIndex(GlobalSecondaryIndex):
read_capacity_units = 2
write_capacity_units = 1
projection = AllProjection()
view = NumberAttribute(default=0, hash_key=True)
class TestModel(Model):
table_name = 'TestModel'
forum = UnicodeAttribute(hash_key=True)
thread = UnicodeAttribute(range_key=True)
view = NumberAttribute(default=0)
view_index = ViewIndex()Now query the index for all items with 0 views:
for item in TestModel.view_index.query(0):
print("Item queried from index: {0}".format(item))It’s really that simple.
