Trying to get batch_size to be 1 to ensure I don't cache any results. The following works in Javascript but the python equivalent doesnt.
import pymongo
connection = pymongo.MongoClient()
mycoll = connection.test.mycoll
mycoll.drop()
mycoll.insert({'x':1,'v':False})
mycoll.insert({'x':2,'v':False})
c = mycoll.find().batch_size(1)
next(c,None)
mycoll.update({'x':2},{'$set':{'v':True}})
next(c,None)
When printing the second record - I expect to get back the record that has been changed. I seem to be seeing a version prior to the change even though I have no batch size set.
In Javascript 0 it works
db.mycoll.drop()
db.mycoll.insert({x:1,v:false})
db.mycoll.insert({x:2,v:false})
var c = db.mycoll.find().batchSize(1)
c.next()
db.mycoll.update({x:2},{$set:{'v':true}})
c.next()
