A collection contains documents. It is uniquely identified by its name which must consist only of hyphen, underscore and alphanumeric characters. There are three types of collections in python-arango:
- Standard Collection: contains regular documents.
- Vertex Collection: contains vertex documents for graphs. See here for more details.
- Edge Collection: contains edge documents for graphs. See here for more details.
Here is an example showing how you can manage standard collections:
from arango import ArangoClient # Initialize the ArangoDB client. client = ArangoClient() # Connect to "test" database as root user. db = client.db('test', username='root', password='passwd') # List all collections in the database. db.collections() # Create a new collection named "students" if it does not exist. # This returns an API wrapper for "students" collection. if db.has_collection('students'): students = db.collection('students') else: students = db.create_collection('students') # Retrieve collection properties. students.name students.db_name students.properties() students.revision() students.statistics() students.checksum() students.count() # Perform various operations. students.load() students.unload() students.truncate() students.configure(journal_size=3000000) # Delete the collection. db.delete_collection('students')
