We need someone proficient in MongoDb NoSQL solutions, who can help us with our concern.
We have over 3,000,000 records, and DB size has blown up to 400 GB of storage space and pretty much filled entire disk space. In result, Mongo DB crashed. We think, that 400 GB is too high for 3 million records. We need to understand, why Mongo has blown out of proportion in terms of disk space usage in comparison to number of records.
Please bid only, if you have good knowledge of the above subject. We will need further recommendations tailored to our specific needs.
