Elasticsearch : How to delete an Index using python
PythonPython 2.7ElasticsearchPython Problem Overview
Forgive me if this is quite basic but I have Python 2.7 and Elasticsearch 2.1.1 and I am just trying to delete an index using
es.delete(index='researchtest', doc_type='test')
but this gives me
return func(*args, params=params, **kwargs)
TypeError: delete() takes at least 4 arguments (4 given)
I also tried
es.delete_by_query(index='researchtest', doc_type='test',body='{"query":{"match_all":{}}}')
but I get
AttributeError: 'Elasticsearch' object has no attribute 'delete_by_query'
Any idea why? Has the api changed for 2.1.1 for python?
Python Solutions
Solution 1 - Python
For ES 8+ use:
from elasticsearch import Elasticsearch
es = Elasticsearch()
es.options(ignore_status=[400,404]).indices.delete(index='test-index')
For older versions use this notation:
from elasticsearch import Elasticsearch
es = Elasticsearch()
es.indices.delete(index='test-index', ignore=[400, 404])
Solution 2 - Python
If you have a document object (model) and you're using elasticsearch-dsl, specially with Python-3.X you can directly call the delete method of your model's _index attribute.
ClassName._index.delete()
Also as it's stated in documentation:
>The _index attribute is also home to the load_mappings method which will update the mapping on the Index from elasticsearch. This is very useful if you use dynamic mappings and want the class to be aware of those fields (for example if you wish the Date fields to be properly (de)serialized):
>
> Post._index.load_mappings()
Solution 3 - Python
Since passing transport options in the API method is deprecated in the Elasticsearch python client 8+, the way to specify HTTP status codes that should be ignored (e.g. to prevent errors in case the target index does not exist) would be by using Elasticsearch.options() now:
from elasticsearch import Elasticsearch
es = Elasticsearch()
es.options(ignore_status=[400,404]).indices.delete(index='test-index')
(see documentation).
Solution 4 - Python
If you're using elasticsearch-dsl, use
from elasticsearch_dsl import Index
index = Index('test-index')
index.delete(ignore=[400, 404])
