Getting Started

This package is a document manager for mongo-connector <https://github.com/yougov/mongo-connector>_ that targets Elasticsearch versions 2.x and 5.x -- don't let the name fool you! For information on running mongo-connector with Elasticsearch, please see the MongoConnector Usage with Elasticsearch <https://github.com/yougov/mongo-connector/wiki/Usage%20with%20ElasticSearch>_ wiki page.

Installation

The installation of the elastic2-doc-manager depends on which version of Elasticsearch you are targeting.

Elasticsearch 1.x

This is the document manager for Elasticsearch 2.x and 5.x. If you want to target Elasticsearch 1.x, please install the elastic-doc-manager <https://github.com/yougov/elastic-doc-manager>_.

Elasticsearch 2.x

For use with an Elasticsearch 2.x server, install with pip <https://pypi.python.org/pypi/pip>__::

pip install 'elastic2-doc-manager[elastic2]'

Elasticsearch 5.x

For use with an Elasticsearch 5.x server, install with::

pip install 'elastic2-doc-manager[elastic5]'

.. note:: Version 0.3.0 added support for Elasticsearch 5.x.

Amazon Elasticsearch Service

To use with Amazon Elasticsearch Service, you must install the required AWS dependencies along with the version of Elasticsearch::

pip install 'elastic2-doc-manager[elastic2,aws]'

Development

You can also install the development version of elastic2-doc-manager manually::

git clone https://github.com/yougov/elastic2-doc-manager.git pip install -e './elastic2-doc-manager[elastic2]'

You may have to run pip with sudo, depending on where you're installing and what privileges you have.

.. note:: Please note that before mongo-connector version 2.2.2, the elastic doc manager was packaged with mongo-connector and only supported Elasticsearch 1.x.

Running the tests

Requirements


1. Copy of the Elastic 2.x Document Manager Github repository

  The tests are not included in the package from PyPI and can only be acquired
  by cloning this repository on Github::

      git clone https://github.com/yougov/elastic2-doc-manager

2. Tox

  Install `tox <https://pypi.org/project/tox>`_.

2. Environment variables

  There are a few influential environment variables that affect the tests. These are
  defined in the tox.ini.

All the tests live in the `tests` directory.

Running tests on the command-line

While the tests take care of setting up and tearing down MongoDB clusters on their own, make sure to start Elasticsearch before doing a full test run!

You can run all the tests with one command (this works in all supported Python versions)::

tox

Error messages


Some of the tests are meant to generate lots of ``ERROR``-level log messages,
especially the rollback tests. mongo-connector logs exceptions it encounters
while iterating the cursor in the oplog, so we see these in the console output
while MongoDB clusters are being torn apart in the tests. As long as all the
tests pass with an `OK` message, all is well.
