KafkaFlow is a .NET framework to create Kafka based applications, simple to use and extend.
KafkaFlow uses Confluent Kafka Client.
- Multi-threaded consumer with message order guarantee
- Middlewares support for producing and consuming messages
- Support topics with different message types
- Consumers with many topics
- Serializer middleware with ApacheAvro, ProtoBuf and Json algorithms
- Schema Registry support
- Compression using native Confluent Kafka client compression or compressor middlewares
- Graceful shutdown (wait to finish processing to shutdown)
- Store offset when processing ends, avoiding message loss
- Supports .NET Core and .NET Framework
- Can be used with any dependency injection framework (see here)
- Fluent configuration
- Admin Web API that allows pause, resume and restart consumers, change workers count and rewind offsets, all at runtime
- Dashboard UI that allows to visualize relevant informations about all consumers and manage them
