  • Data size in MongoDB is typically higher due to e.g. each document has field names stored it
  • less flexibity with querying (e.g. no JOINs)
  • no support for transactions - certain atomic operations are supported, at a single document level
  • at the moment Map/Reduce (e.g. to do aggregations/data analysis) is OK, but not blisteringly fast. So if that's required, something like Hadoop may need to be added into the mix
  • less up to date information available/fast evolving product
