Crate fdb_rl

FoundationDB Record Layer

This crate is work-in-progress.

At this time, the thinking with Record Layer is that it will consist of a schema (RecordSchema) containing multiple RecordEntitys.

Each RecordEntity will map to seralized byte array such as a Protobuf Message and will have a primary key tuple and optionally one or more secondary indexes.

This crate will provide:

• APIs for Schema and Index management.

• Ensure transactionally consistent secondary indexes during inserts, updates and deletes.

• A very simple API for querying based on primary key and secondary indexes.

In addition, a simple transactionally consistent queuing system similar to QuiCK will also be implemented.

There are no plans to implement a query planner or other higher level database features.
