Will any of these layers on top be open-sourced? FDB itself is rather low-level and will result in duplicate efforts building another SQL/data layer.

It's rather interesting to see how many companies have been using FoundationDB silently this whole time...

To be clear we haven't built a SQL layer on top of FDB. It's a metadata store for us where we store objects. We haven't decided whether to open source the object-mapping layer. It's plausible, and if we do it will take some work. But we are certain to contribute to the FDB community. So do keep an eye out.

@ashishnm, Thanks for sharing, after I read the HN excitement around the open sourcing of foundationdb, I had a question in my mind and I hope it's not to off-topic to ask here - do you happened to know is it feasible to implement a SQL Layer on top of foundationdb, using Sqlite's Virtual Table mechanism (http://www.sqlite.org/vtab.html)?

So when FoundationDB was acquired, Snowflake kept using it as some sort of internal fork? Wow

Yes, we kept using FoundationDB, primarily because of its reliability. The layers we built on top don't have knowledge of the underlying architecture.

Yeah, I’m curious to know how this worked.

not a fork. they got it via an escrow
