My bet is that it is built on top of Aurora PostgreSQL. By looking at the "Limits" section ( https://docs.aws.amazon.com/documentdb/latest/developerguide... ), identifiers are limited to 63 characters and the same characters that PostgreSQL limits identifiers to; and a collection size limit of 32TB, coincidentally maximum PostgreSQL table size. Edit: I can confirm: does not allow the UTF-8 null character in strings:…

Not sure why I'm getting downvoted. The characteristics sound exactly like Aurora. - "replicates six copies of your data across three AWS Availability Zones (AZs)" [0] - "Amazon DocumentDB uses a distributed, fault-tolerant, self-healing storage system that auto-scales up to 64 TB per database cluster."

Yeah, downvoting is totally broken on Hacker News. Seems like anything that isn't immediately agreed-with gets downvoted. I don't know where all the small-minded people come from, but they seem to have found their home here.

There is just some random noise. It might just have gotten one downvote. Now it's the top-comment.

I love Azure for this. The names are almost all extremely straightforward. There are a handful that have made the jump from confusing to straight forward, and a handful that have made the jump from straightforward to confusing (CosmosDB, formerly DocumentDB, chiefly comes to mind).

Agreed. Too bad the Azure portal is the polar opposite. AWS, for all its faults, is mostly just a boring HTML portal but it works. Azure tried to get fancy, with side sliding panels all over the place, and it is barely useable. The nicest thing I can say is it is "quirky." It isn't really productive however, particularly not on my 1080p monitor at Windows 10's default 125% DPI. I literally quit Azure's Application In…

Azure Portal feels like if someone tried to make the Xbox 360 blade interface into an admin tool, without first asking the admins what they needed.

If I'm reading the pricing page correctly, DocumentDB would run a _minimum_ of $200/month. That's for the smallest instance and no storage or I/O. Kind of steep if you ask me.

Seems to be really aimed at businesses which want to get off of MongoDB desperately.

50GB is a really small data set.

Eh, by what measure? Realistically it's probably bigger than 90% of all Mongo datasets. It's tiny if you're a massive company and it's massive if you're a tiny startup.

50GB easily fits in RAM. It's a small dataset.

If you can run the dataset comfortably on a Macbook then it's very, very small.

Heck, you can even just use grep over 50GB reading straight from disk. It's tiny.

Sounds like this runs on the same storage service as Aurora.

I'm guessing if you would have included this reasoning in your original comment, then it wouldn't have been downvoted.
