To share a quick context, Mongo DB is used as the database to persist information for the application. We use a tool called Pentaho which makes connection to the Mongo DB to extract data and generates few reports for the business. As the data in the application has grown up, we are reaching 16MB size on Mongo due to which the query operation fails and hence the reports fails.
