Description
After almost three years of development, the first developer preview of Kronotop is out.Kronotop is a distributed multi-model database built on FoundationDB.Our motto is: One transaction, multiple models.Documents, ordered key-value data, and other models can participate in the same strictly serializable transaction, even across namespaces.I'd love to hear your feedback.

Could you build this?
No Kronotop is a distributed multi-model database engine built on top of FoundationDB, requiring deep database internals knowledge, serializable isolation semantics, and distributed systems engineering.
What it would actually take: Building this requires systems programming (Rust, C++, or Go) interfacing with FoundationDB's C API to map document models, ordered key-value engines, and indexing strategies onto transactional FDB keyspaces. The hard parts include designing custom storage encodings, building a query engine that maintains strict serializability across distinct data models, and managing distributed query execution and index maintenance.
