Coincidentally, I wrote an article today on how I use it for similar scenarios. It can fetch from S3, multiple databases at once, and so on.
And you get all the benefits of a database when you need to join or postprocess data from multiple sources.
I’ll still check this out though.
I'm sure SREs will really love me doing expensive adhoc queries against production postgres /s
I've yet to work in enterprises big enough to have multi cloud data warehouses though, maybe it's more useful in that setting?
