ESClient is a Python library that uses the ElasticSearch REST API. It is meant to be lightweight and be close to the actual REST API in terms of usage.
With ESClient comes two scripts that are installed in your /usr/local/bin:
- esdump -- Use this script to dump one or more indexes to a file (or stdout)
- esimport -- Use this script to import a dump
The only shortage with these two tools is that they do not make a backup of the mappings yet. This is however planned for an upcoming version.
python setup.py install
You can also install ESClient with easy_install or pip. The following commands will install the latest released version of ESClient:
$ easy_install esclient
Or with pip:
$ pip install esclient
Please take a look at the test_esclient.py file for usage examples. This code at least covers all the API methods that are implemented. As soon as the API reaches stability I will put more time into writing decent documentation. I advice you to keep the ElasticSearch documentation at hand when you start using this library. The documentation strings in the code should be very useful.
test_esclient.py can be used for unit testing. You can directly run this file if you have an ElasticSearch instance running on localhost.
If you find a bug or any other issue you may create an issue on GitHub!
My target is to reach a stable 1.0 release. Currently on the roadmap to reach such a 1.0 release are:
- Implementing most or even all the API methods
- Adding support for backing up the mappings with esdump and esimport
- Adding option to esdump to save data into multiple files, with names based on the name of the source index
- ESClient uses the excellent requests library.
- The unit tests only work on Python 2.7 (one test will fail on 2.6)
- The code is tested mostly on Python 2.6 and 2.7
- Added esdump script, which can dump indexes to a (optionally compressed) file or stdout by using the new scan and scroll methods
- Added two methods: scan and scroll. With these methods you can now perform scan queries and scroll through the results.
- fixed an issue where the dependency on the requests library was not automatically procesed by easy_install / pip
- Better error handling (by using _parse_json_response() method everywhere)
- Added API methods: get_mapping, put_mapping
- Removed option to choose between JSON or hierachy of Python objects. It would have created too much hassle.
- Added API methods: mget, open+close index, create_alias, delete_alias
- small fixes here and there
- Added docstring to the get API
- made sure that makedist.sh removes old MANIFEST file before making new package
- fixed version string in esclient.py
From now on I will conform to the Semantic Versioning Guidelines outlined on this site: http://semver.org/ In that spirit, I bumped the minor version to 0.1.0 and will keep doing so until public API stability is reached.
