Mongodb automatically create schema collections

[Yulias Stolin]

Hi
I know that mongo creates things on the fly. But I would like to have
some script for creating schema (db) collections, and each time that
new schema (db) is created (on the fly) mongo will automatically
execute this script. So my code will be unaware of indexes and sharing
configuration. Can I do such thing, and how?

Not 100% sure what you mean by creating things on the fly, but it sounds like you want triggers on the server.  There is a request tracking this that you can watch and vote for:

https://jira.mongodb.org/browse/SERVER-124

But, it does not exist yet and is not scheduled for implementation.  At the moment, therefore, you need to do this type of thing client side.

This may also apply: http://www.mongodb.org/display/DOCS/Server-side+Code+Execution

But again, you're a little vague about what you are trying to accomplish.

I have an application with multiple accounts. In each account i have
the same tables.
The account could be created dynamically (this is rare event no
special business logic on that)
But in other hand i didn't want to treat at the code the new account
creation, and then ensure an index for the collections, and configure
their shard definition
So I wanted something automatic in mongo. Probably it is not possible

This is best put in your business logic/code when new accounts are created.

Wherever the code is that uses the database for the first time could
also set everything up correctly before.
