Apache Camel
Apache Camel is an open-source integration framework developed by the Apache Software Foundation that implements Enterprise Integration Patterns (EIPs) for connecting systems, services, and data. It provides a domain-specific language (DSL) in Java, XML, YAML, and Kotlin for defining routes between components. Camel ships with over 300 components for connecting to messaging systems, databases, cloud services, APIs, and file formats. Camel K extends this with a Kubernetes-native integration runtime and operator with a REST management API.

The Apache Camel Java DSL provides a fluent API for defining integration routes using Enterprise Integration Patterns. Developers define RouteBuilder subclasses to connect Camel...
Apache Camel REST DSL API
The Apache Camel REST DSL provides a concise syntax for exposing and consuming RESTful services within Camel routes. It supports both REST service definition and REST proxy/cons...
Apache Camel K Operator API
The Apache Camel K Operator exposes a Kubernetes Custom Resource API for deploying and managing Camel integrations as cloud-native serverless workloads on Kubernetes and OpenShift.
Apache Camel Quarkus API
Apache Camel Quarkus provides native compilation and fast startup of Camel routes on Quarkus, enabling serverless and microservice deployments with Camel's integration components.
Features
Implementation of 65+ EIPs including splitter, aggregator, content-based router, message translator, and dead letter channel.
Pre-built connectors for messaging (Kafka, ActiveMQ, RabbitMQ), cloud (AWS, Azure, GCP), databases, REST, SOAP, and file formats.
Define routes in Java, XML, YAML, Kotlin, or Groovy DSL with full feature parity across languages.
Concise DSL for exposing and consuming RESTful services with OpenAPI/Swagger integration.
Deploy Camel integrations as cloud-native serverless workloads on Kubernetes and OpenShift.
Native compilation of Camel routes with Quarkus for fast startup and low memory serverless deployments.
Built-in support for 50+ data format conversions including JSON, XML, CSV, Avro, Protobuf, and EDI.
Parameterized route templates for building reusable integration patterns.
Distributed transaction support using the saga pattern with compensating actions.
