ApertureDB Client Python Module

This is the Python SDK for building applications with ApertureDB.

This comprises of utilities to get data in and out of ApertureDB in an optimal manner. A quick getting started guide is useful to start building with this SDK. For more concrete examples, please refer to:

• Simple examples and concepts
• Advanced usage examples
• Sample applications

Installing in a custom virtual environment

pip install aperturedb[complete]

or an installation with only the core part of the SDK

pip install aperturedb

A complete reference of this SDK is available on the official ApertureDB Documentation

Development setup

The recommended way is to clone this repo, and do an editable install as follows:

git clone https://github.com/aperture-data/aperturedb-python.git
cd aperturedb-python
pip install -e .[dev]

Running tests

The tests are inside the test dir. Currently these get run in Linux container. Refer to docker/tests and test/run_test_container for details. Following explanation assumes that the current working directory is test.

The tests bring up a set of components in an isolated network, namely:

• aperturedb-community
• lenz
• nginx
• ca (for initial provisioning of certificates)
• webui

To connect to this setup, the ports are exposed to the host as follows:

• 55556 for TCP connection to aperturedb (via lenz).
• 8087 for HTTP connection to aperturedb (via nginx).

This can be done manually as:

docker compose up -d

Changes to run the tests in development environment.

Edit the file test/dbinfo.py to loook like the following.

• DB_TCP_HOST = localhost
• DB_REST_HOST = localhost
• DB_TCP_PORT = 55556
• DB_REST_PORT = 8087

All the tests can be run with:

export GCP_SERVICE_ACCOUNT_KEY=<content of a GCP SERVICE ACCOUNT JSON file>
bash run_test.sh

Running specific tests can be accomplished by invoking it with pytest as follows:

PROJECT=aperturedata KAGGLE_username=ci KAGGLE_key=dummy coverage run -m pytest test_Session.py -v -s --log-cli-level=DEBUG

NOTE:The running environment is assumed to be Linux x86_64. There might be certain changes required for them to be run on MacOS or Windows python environments.

Certain Environment variables that affect the runtime beaviour of the SDK.

These can be used as debugging aids.

Variable	type	Comments	Default value
ADB_DEBUGGABLE	boolean	allows the application to register a fault handler that dumps a trace when SIGUSR1 is sent to the process	not set
LOG_FILE_LEVEL	log levels	The threshold for emitting log messages into the error.log file	WARN
LOG_CONSOLE_LEVEL	log levels	The threshold for emitting log messages into stdout	ERROR
ADB_LOG_FILE	string	custom file path for the LOG file	not set

Reporting bugs

Any error in the functionality / documentation / tests maybe reported by creating a github issue.

Development guidelines

For inclusion of any features, a PR may be created with a patch, and a brief description of the problem and the fix. The CI enforces a coding style guideline with autopep8 and a script to detect trailing white spaces.

If a PR encounters failures, the log will describe the location of the offending line with a description of the problem.
