Hello,

I am working with a data source from the US deparment of education ( http://ope.ed.gov/accreditation/). There are just over 26 thousand rows in the csv file. My code happily inserts java objects into my mongo repository. Unfortunately, it silently disgards about 2/3 of them. For example, if I insert the first 10 rows from the csv into Mongo, only 3 are recorded. Why?

Is there some error(code/exception/log) I am ignoring on inserts which do not work? Things I thought to check.

  1. Added a try block with a catch block for both DataAccessException and Exception. No exception thrown.
  2. I see no error messages in the mongo.log file
  3. MongoTemplate.insert() returns void (ie, no error code).


Consider

Code:
@Document(collection="institutions")
public class AccreditedPostsecondaryInstitution extends Places {
	@SuppressWarnings("unused")
	@Id
	private String instituteId;
Turns out the instituteId which I thought was unique for each row isn't unique. What is suppose to happen in this case? It appears to silently ignore inserts where the @Id already exists. Is that right? Is there a way to make this collision explicit during debugging?
