For what it's worth, Document DB doesn't support a lot of the Mongo API, such as $$ROOT in aggregations, and it can't use indices on (paraphrased) "SELECT * FROM x WHERE id IN [list]" if the list length is > 10.
If you ask me, if there's something worse than Mongo it's Document DB.
- scarface74 6y agoGiven a choice between the limitations of DynamoDB and DocumentDB, DocumentDB is still far more versatile and written on top of the same storage engine and is just as reliable. And yes I know most of the data modeling tricks around using GSI’s and LSI’s.
