ddbmock -- a DynamoDB mock implementation. Presentation ============ `DynamoDB <http://aws.amazon.com/dynamodb/>`_ is a minimalistic NoSQL engine provided by Amazon as a part of their AWS product. **DynamoDB** allows you to store documents composed of unicode, number or binary data as well are sets. Each tables must define a ``hash_key`` and may define a ``range_key``. All other fields are optional. **DynamoDB** is really awesome but is terribly slooooow with managment tasks. This makes it completly unusable in test environements. **ddbmock** brings a nice, tiny, in-memory or sqlite implementation of DynamoDB along with much better and detailed error messages. Among its niceties, it features a double entry point: - regular network based entry-point with 1:1 correspondance with stock DynamoDB - **embeded entry-point** with seamless boto intergration 1, ideal to avoid spinning yet another server. **ddbmock** is **not** intended for production use. It **will lose** your data. you've been warned! I currently recommend the "boto extension" mode for unit-tests and the "server" mode for functional tests. Installation ============ :: $ pip install ddbmock Developing ========== :: $ hg clone ssh://hg@bitbucket.org/Ludia/dynamodb-mock $ pip install nose nosexcover coverage mock webtest boto $ python setup.py develop $ nosetests # --no-skip to run boto integration tests too What is ddbmock *not* useful for ? ================================== Do *not* use it in production or as a cheap DynamoDB replacement. I'll never stress it enough. All the focus was on simplicity/hackability and simulation quality. Nothing else. What is ddbmock useful for ? ============================ - FAST and RELIABLE unit testing - FAST and RELIABLE functional testing - experiment with DynamoDB API. - RELIABLE throughput planification - RELIABLE disk space planification - almost any DynamoDB simulation ! ddbmock can also persist your data in SQLITE. This open another vast range of possibilities :) Current status ============== - pass all boto integration tests - support full table life-cycle - support full item life-cycle - support for all item limitations - accurate size, throughput reporting - no limits on concurent table operations - no limits for request/response size nor item count in these See http://ddbmock.readthedocs.org/en/latest/pages/status.html for detailed up-to-date status. History ======= - v1.0.0 (*): full documentation and bugfixes - v0.4.1: schema persistence + thread safety, bugfixes - v0.4.0: sqlite backend + throughput statistics + refactoring, more documentation, more tests - v0.3.2: batchWriteItem support + pass boto integration tests - v0.3.1: accuracy in item/table sizes + full test coverage - v0.3.0: first public release. Full table lifecycle + most items operations (?) indicates a future release. These are only ideas or "nice to have". Example usage ============= Run as Regular client-server ---------------------------- Ideal for test environment. For stage and production I highly recommend using DynamoDB servers. ddbmock comes with no warranty and *will* **loose your data(tm)**. Launch the server :: $ pserve development.ini # launch the server on 0.0.0.0:6543 Start the client :: import boto from ddbmock import connect_boto_network # Use the provided helper to connect your *own* endpoint db = connect_boto_network() # Done ! just use it wherever in your project as usual. db.list_tables() # get list of tables (empty at this stage) Note: if you do not want to import ddbmock only for the helper, here is a reference implementation: :: def connect_boto_network(host='localhost', port=6543): import boto from boto.regioninfo import RegionInfo endpoint = '{}:{}'.format(host, port) region = RegionInfo(name='ddbmock', endpoint=endpoint) return boto.connect_dynamodb(region=region, port=port, is_secure=False) Run as a standalone library --------------------------- Ideal for unit testing or small scale automated functional tests. Nice to play around with boto DynamoDB API too :) :: import boto from ddbmock import connect_boto_patch # Wire-up boto and ddbmock together db = connect_boto_patch() # Done ! just use it wherever in your project as usual. db.list_tables() # get list of tables (empty at this stage) Note, to clean patches made in ``boto.dynamodb.layer1``, you can call ``clean_boto_patch()`` from the same module. Requirements ============ - Python 2.7.x - Pyramid >= 1.3 - Boto >= 2.5.0 (optional) - **NO** AWS account :) Related Links ============= ddbmock ------- - **Full documentation**: https://ddbmock.readthedocs.org/en/latest - **Report bugs**: https://bitbucket.org/Ludia/dynamodb-mock/issues - **Download**: http://pypi.python.org/pypi/ddbmock Dynamodb-mapper --------------- - **Full documentation**: http://dynamodb-mapper.readthedocs.org/en/latest/ - **Report bugs**: https://bitbucket.org/Ludia/dynamodb-mapper/issues - **Download**: http://pypi.python.org/pypi/dynamodb-mapper Boto ---- - **Full documentation**: http://docs.pythonboto.org/en/latest/index.html - **Report bugs**: https://github.com/boto/boto/issues - **Download**: http://pypi.python.org/pypi/boto
