SQLite & HCTree

Given that FoundationDB is built on top of SQLite, I wonder if that team is eyeing the HCTree engine for it.

It's still in experimental mode but provides literally 10x improvement on read/writes to SQLite.

Given Apple size & scale of iCloud, that seems like a massive win for them if that engine for SQLite can mature to production stability.

They have built their own storage engine named Redwood, which has some very FoundationDB-specific optimizations (like prefix compression). Check out the "Storage Servers" section in this doc: https://apple.github.io/foundationdb/architecture.html

FoundationDB only uses the b-tree implementation and even that I don't know if it is still used as they switched storage engines I think.

Yes, to RocksDB.
