Wavefront's co-founder just tweeted this: https://twitter.com/panghy/status/987022825457266689

Finally it's out! @WavefrontHQ managaes petabyte scale clusters with #foundationdb today!

I'm confused. How they could use FoundationDB when Apple aquired it a long time ago? Did apple sell the software to other companies?

FoundationDB was a company that existed in the market, licensing our database technology for quite a while. Licenses don't necessarily terminate upon acquisitions.

We worked on the codebase independently (we have escrow). We run petabyte-scale clusters in aws.

Maybe CloudKit? I was looking at the documentation for it recently and it's a key-value store.

CloudKit is using Cassandra/Solr:

From what I have heard, CloudKit is an API abstraction either of Cassandra/Solr and more recently Foundation DB.

So new CloudKit codebase nowadays is being run on top of Foundation DB

I had always assumed they acquired the team more than the ip. I'm not sure this confirms that or not. I'd be curious what the answer to this question is as well, but wouldn't be surprised if the answer was "they don't"

My first thought was...iCloud?

iCloud is an umbrella term for several different systems.

Right. All I'm saying is that FoundationDB is underneath it somewhere.
