Hive ACID solves a similar set of problems with a similar design (base Parquet/ORC files + delta files in the same format). It's a bit more "managed" in that compaction is automatic and it supports features like column-level access control, which aren't possible when you're executing an end-user's Scala code against a directory of files.
