dfanout allows you to manage request paths with a lot of flexibility.
Introduce new fanouts, or chain different fanouts to dynamically manage
your HTTP or RPC endpoints with minimal or no code changes.
dfanout provides observability
into the health and performance of request paths out of the box.
Perform data migrations with confidence, or repurpose your request paths
with minimal efforts.
- Data migrations where you want to implement dual reads and/or dual writes with minimal or no code changes.
- Populating new datastores or message queues without code changes or new hooks.
- Improve the auditing capabilities for read and write paths with minimal or no code changes.
- Managing retry or security policies of your read and write path with minimal or no code changes.
- Limited to HTTP endpoints (e.g. REST endpoints) for now. Native gRPC and Twirp support is coming in the future.
- No transactional capabilities, e.g. no rollbacks on partial failures.
- Endpoints should share the request and response contract.
