> eg 2: Financial data) What's the price of stock X over the past 5 years

This is so incredibly frustratingly slow to pull on FactSet and Capital IQ, it makes me want to pull my hair every time I have to build line charts over time for a period greater than 2 years

Sounds like you need a time-seres database for those sorts of narrow and deep queries :)

What's difficult is to find a database that has good performance on both narrow and deep queries (e.g Price of stock X for past 5 years) as well as shallow and wide queries (e.g Price of all stocks in past 15mins)
