For example I have new sequence of documents to write with _ids:
[1, 2, 3, 4, 5, 6, 7]
and already stored collection of documents with _ids:
[3,4,7].
I want to store my new sequence with command InsertBatch and do not wanna to check every _id for existing. Ofcourse Mongo will throw exception because of collision and collection will have only part of new sequence:
[3,4,7,1,2]
How could I solve this problem?
If you are using MongoDB 2.0, you can set the
continueOnErrorflag tofalseto achieve this behavior. See http://www.mongodb.org/display/DOCS/Inserting#Inserting-Bulkinserts for details, and consult the API documentation for your driver to find out how to use this from your application.
