kestrel
Simple DDD toolkit for Kotlin
TODO
- Complete the reactive refactor
- Testing different failure scenarios
- Add reporters back in
- General testing
- HTTP event sources
- Database backend
- Projections
- Stateful process manager support
- Should have snapshotting support too
- Switch stateless process manager to be similar to stateful one (e.g. explicit domain service dependency)
- Register (stateless) process managers with application rather than start themselves
- Eventually consistent (async) DB projections (db offset manager)
- Support for dry run command handling (i.e. handle command but don't persist events)
- Utilise Reactor metrics to gather useful metrics
- Type-safe SQL string builder (maybe fork initially from Ktorm)
- Support for storing events not tied to aggregates
- Simple non-event sourced aggregate support
- Simple command handling (no behaviours)
- State serialisation (Object -> DB). ORM...
- Optional event generation
- Should be able to re-use most of existing code
- Kestrel application bootstrap module (e.g. KestrelRdbmsApplication)
- Debezium + Kafka/Kinesis stream support
- Default JSON mapper functionality for v1 of events? Or maybe at least code generation?
- Create CLI toolbelt for auto generation of skeleton code
- Document need for adequate indexes on domain_event table
- Websocket events subscriptions and streams - abstract difference between fetching straight from backend store or via external stream (kafka/kinesis)
- Transparent leader election to prevent multiple subscriptions receiving duplicates
- Command deduplication - remember and return prior rejections
