What's the big deal about key-value databases like FoundationDB ands RocksDB?

• RethinkDB

  25 26,518 5.5 C++

  The open-source database for the realtime web.

  

No I don't think that's relevant. They implement their own btree it seems [0].

They don't use a key-value store library.

I know it's a bit of a fine line. But I'm talking about standalone libraries people embed across different applications/databases. That's what RocksDB/LevelDB/Pebble are.

• go-sstables

  4 251 4.0 Go

  Go library for protobuf compatible sstables, a skiplist, a recordio format and other database building blocks like a write-ahead log. Ships now with an embedded key-value store.

I highly recommend people comfortable with Go checkout the building blocks at https://github.com/thomasjungblut/go-sstables

This codebase shows how SSTables, WAL, memtables, skiplists, segment files, and plenty of other storage engine components work in a digestible way. Includes a demo database showing how it all comes together.

• hse

HSE[0] is another storage engine to throw on the pile.
