сейчас блокировка не на коллекцию, а на базу. Т.е. пока у вас идет запись в одну коллекцию у вас запись в другую коллекцию в этой же базе — блокирована.

у каждого инстанса монги может быть несколько баз данных; каждая база данных представляет собой список (массив) коллекций; каждая коллекция, в свою очередь, представляет собой массив JSON-документов произвольного формата. Вот в этой новой версии при обновлении какого-нибудь документа блокировка будет не на всю коллекцию, в которой он состоит, а только на сам документ.

mongoimport --help

imports CSV TSV and JSON

mongoimport -stopOnErrors -db .. -collection .. < file.txt

cursor = things.find().skip(3).limit(1).sort('value',pymongo.DESCENDING)

Do you expect the second insert below to succeed?

# get a handle to the school database db=connection.school people = db.people doc = {"name":"Andrew Erlichson", "company":"10gen", "interests":['running', 'cycling', 'photography']} try: people.insert(doc) # first insert del(doc['_id']) people.insert(doc) # second insert except: print "Unexpected error:", sys.exc_info()[0]

import pymongo import sys # establish a connection to the database # note this uses the now deprecated Connection class, as we did in the lecture. # MongoClient is the preferred way of connecting. connection = pymongo.Connection("mongodb://localhost", safe=True) # get a handle to the school database db=connection.school scores = db.scores try: doc = scores.find_one() except: print "Unexpected error:", sys.exc_info()[0] print doc

search for all quiz scores that are greater than 20 and less than 90.

import pymongo import sys # establish a connection to the database connection = pymongo.Connection("mongodb://localhost", safe=True) # get a handle to the school database db=connection.school scores = db.scores def find(): print "find, reporting for duty" query = {'type':'quiz', 'score':{'$gt':20, '$lt':90}} try: iter = scores.find(query) except: print "Unexpected error:", sys.exc_info()[0] return iter find()

what do you think will happen if a document that matches the query doesn't have a key called media.oembed.url?

import pymongo import sys # establish a connection to the database connection = pymongo.Connection("mongodb://localhost", safe=True) # get a handle to the reddit database db=connection.reddit scores = db.stories def find(): print "find, reporting for duty" query = {'media.oembed.type':'video'} projection = {'media.oembed.url':1, '_id':0} try: iter = scores.find(query, projection) except: print "Unexpected error:", sys.exc_info()[0] sanity = 0 for doc in iter: print doc sanity += 1 if (sanity > 10): break find()

pymongo will return the empty document

MongoClient is new connection class

find . -name "*.py" -type f -exec grep -i "MongoClient" '{}' \; -print
