Do you love MongoDB, but wish it was slower, more expensive, and even less reliable? Then CosmosDB may be the database for you.

We use comos and we used to use mongo. It's a lot less hands off then mongo.

Frankly, I do not know why people don't build things on Kusto.

I haven't even heard of Kusto until now...

It sucks, is expensive, and was designed by someone who was fired.

Do you have some sources? What was they fired for? I thought they got Leslie Lanport to design it

Why would he still work for Microsoft if he was fired?

He probably is jokingly referring to the Nokia acquisition, which at that time is ran by an ex-Microsoft executive, whom rejoins Microsoft after the acquisition.

Sorry but small correction:

s/ran by/ran into the ground by/g

Oh yes, I forgot about that important detail. MS was able to buy at a greatly discounted price due to that.
