How to import data from mongodb to pandas?
pymongo
might give you a hand, followings are some codes I'm using:
import pandas as pdfrom pymongo import MongoClientdef _connect_mongo(host, port, username, password, db): """ A util for making a connection to mongo """ if username and password: mongo_uri = 'mongodb://%s:%s@%s:%s/%s' % (username, password, host, port, db) conn = MongoClient(mongo_uri) else: conn = MongoClient(host, port) return conn[db]def read_mongo(db, collection, query={}, host='localhost', port=27017, username=None, password=None, no_id=True): """ Read from Mongo and Store into DataFrame """ # Connect to MongoDB db = _connect_mongo(host=host, port=port, username=username, password=password, db=db) # Make a query to the specific DB and Collection cursor = db[collection].find(query) # Expand the cursor and construct the DataFrame df = pd.DataFrame(list(cursor)) # Delete the _id if no_id: del df['_id'] return df
You can load your mongodb data to pandas DataFrame using this code. It works for me. Hopefully for you too.
import pymongoimport pandas as pdfrom pymongo import MongoClientclient = MongoClient()db = client.database_namecollection = db.collection_namedata = pd.DataFrame(list(collection.find()))
Monary
does exactly that, and it's super fast. (another link)
See this cool post which includes a quick tutorial and some timings.
