fdb-etcd 
An experiment to provide ETCD layer on top of FoundationDB, built with Record-Layer and Vert.x.
Features
- etcd protobuf was imported and exposed with Vert.x,
- Record-layer is used. As etcd is also using protobuf, we are directly storing the KeyValue message,
- Integrations test using a real FDB spawned with testcontainers and official Java etcd client,
- Tests are backported from jetcd test cases
- Supported operations:
- put,
- get,
- scan,
- delete,
- compact,
- leases,
- watches,
- ETCD MVCC simulated using FDB's read version
- multi-tenancy (soon back by the AuthService)
For TODO's, please have a look to the Github issues.
