Repeated build index on insert operation

[VISHAL KUMAWAT]

Hi,

In MongoEngine version 0.8.7, For every document insert, Its rebuilding all indexed defined in meta attribute. Following is code snippet to replicate the issue.

from mongoengine import connect

from mongoengine import DynamicDocument

from mongoengine import Document

from mongoengine.connection import get_db

from mongoengine import *

conn = connect( 'test',   

    host=''

)

class Test(Document):

meta = {

'indexes': [

            {

             'fields': ['value']                

            },

            {

               'fields': ['#customer']

            },

            {

               'fields': ['#_id']

            }

         ]

   }

name = StringField()

value = StringField()

customer = StringField()

if __name__ == '__main__':

for num in range(1,20): 

ross = Test(name= str(num), value =str(num), customer = "customer" + str(num)) 

obj = ross.save()

When first document inserted, all indexes would be created and in place. In my case, mongo server is rebuilding these three indexes for each document I insert( 20 times in above example ) . These cause severe impact on server performance. 

Regards,

Vishal

I don't know why it's doing that, but you can set a flag to stop automatic index creation:

meta = {

    'auto_create_index': False,
