Delete Index With PyArango

I am using Python to create some background services and web service in the office. For the database, we are using Arangodb for our main database, so we use PyArango to connect to the database.

At a time, I need to delete index in the database collection, but I cannot find any example related to index deletion. So after reading the code and API documentation, I will share the example here.

Connect to database

from pyArango.connection import Connection

conn = Connection(arangoURL='http://<host>:<port>', username='user', password='pass')
db = conn['dbname']

collname = db['collname']

To get index list, we can use getIndexes()


We will get the index list and the index object

{'primary': {'collname/0': <pyArango.index.Index object at 0x7f44404b85c0>}, 'hash': {'collname/7490651': <pyArango.index.Index object at 0x7f44404b8860>, 'collname/7490654': <pyArango.index.Index object at 0x7f44404b8828>}, 'skiplist': {}, 'geo': {}, 'fulltext': {}}

Before we continue, we could see the detail of index class at the github page Then we will try list the attributes of index object.


Index attributes:

['URL', '__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', '_create', 'collection', 'connection', 'delete', 'indexesURL', 'infos']

We could see the index information with collname.getIndexes()[‘hash’][‘collname/7490654’].infos

{'deduplicate': True, 'fields': ['keyTime'], 'id': 'collname/7490654', 'selectivityEstimate': 0.007465129984938773, 'sparse': False, 'type': 'hash', 'unique': False}

If we want to delete the index, just call the delete method.


We will get any success response after deleting the index.
