aerospike 2.2.3

Aerospike Client Library for Python

Dependencies

The Python client for Aerospike works with Python 2.7, 3.4, 3.5, 3.6 running on 64-bit OS X 10.9+ and Linux.

The client depends on:

• Python devel package

• OpenSSL

• The Aerospike C client

RedHat 6+ and CentOS 6+

The following are dependencies for:

• RedHat Enterprise (RHEL) 6 or newer

• CentOS 6 or newer

• Related distributions which use the yum package manager

sudo yum install python-devel
sudo yum install openssl-devel

Debian 6+ and Ubuntu 12.04+

The following are dependencies for:

• Debian 6 or newer

• Ubuntu 12.04 or newer

• Related distributions which use the apt package manager

sudo apt-get install python-dev
sudo apt-get install libssl-dev

OS X

By default OS X will be missing command line tools. On Mavericks (OS X 10.9) and higher those can be installed without Xcode.

xcode-select --install # install the command line tools, if missing

OpenSSL can be installed through the Homebrew OS X package manager.

brew install openssl

Install

Aerospike Python Client can be installed using pip:

pip install aerospike

# to troubleshoot pip versions >= 6.0 you can
pip install --no-cache-dir aerospike

# to trouleshoot installation on OS X El-Capitan (10.11) or OS X Sierra (10.12)
pip install --no-cache-dir --user aerospike

If you run into trouble installing the client on a supported OS, you may be using an outdated pip. Versions of pip older than 7.0.0 should be upgraded, as well as versions of setuptools older than 18.0.0.

Lua files

The system .lua files used for client side aggregation will be installed. By default pip will install the .lua files in a subdirectory named aerospike/lua/ inside of the Python installations directory for platform specific files. The location of the files can be found by running:

pip show -f aerospike

Note If the .lua files are stored somewhere besides /usr/local/aerospike/lua. and you wish to perform Stream UDF operations it will be necessary to specify the locations of the system modules as a configuration parameter to the Aerospike client constructor:

config = {‘hosts’: [(‘127.0.0.1’, 3000)], ‘lua’: {‘system_path’: ‘/path/to/lua’} …} my_client = aerospike.client(config)

OS X Installation

Upgrading pip on OS X El-Capitan (10.11) or OS X Sierra(10.12) runs into SIP issues with pip install --user aerospike as the recommended workaround to install aerospike on those versions of OS X.

Attempting to install the client with pip for the system default Python may cause permssions issues when copying necesarry files. In order to avoid those issues the client can be installed for the current user only with the command: pip install --user aerospike

If the version of Python is not in the officially supported list, or the --install-option argument is provided, pip will attempt to compile the client from source. Please see the build directions in the GitHub repository to troubleshoot any issues caused by compiling the client.

Build

For instructions on manually building the Python client, please refer to the BUILD.md file in this repo.

Documentation

Documentation is hosted at aerospike-python-client.readthedocs.io and at aerospike.com/apidocs/python.

Examples

Example applications are provided in the examples directory of the GitHub repository

For examples, to run the kvs.py:

python examples/client/kvs.py

Benchmarks

To run the benchmarks the python module ‘tabulate’ need to be installed. In order to display heap information the module guppy must be installed. Note that guppy is only available for Python2. If guppy is not installed the benchmarks will still be runnable. Benchmark applications are provided in the benchmarks directory of the GitHub repository

By default the benchmarks will try to connect to a server located at 127.0.0.1:3000 , instructions on changing that setting and other command line flags may be displayed by appending the –help argument to the benchmark script. For example:

python benchmarks/keygen.py --help
