Apache Camel 3.19 has just been released.
This release introduces a set of new features and noticeable improvements that we will cover in this blog post.
Camel JBang (Camel CLI)
In this release we continue the expansion of Camel CLI.
You can now easily manage local running Camel integrations.
For example to list all running Camel processes:
camel ps PID NAME READY STATUS AGE 61818 sample.camel.MyCamelApplica… 1/1 Running 26m38s 62506 dude 1/1 Running 4m34s
To see a bit more information, you can use
Suppose you have two running integrations, then you can manage them, such as stop (with
camel stop <integration-name-or-pid>), or stop/start routes (with respectively
camel cmd stop-route --id=<id-route> <integration-name-or-pid>/
camel cmd start-route --id=<id-route> <integration-name-or-pid>) etc:
camel stop dude Stopping running Camel integration (pid: 62506)
There is a lot more that Camel JBang can do, so make sure to see the Camel JBang documentation. It is also a good idea to run
camel --help to list all available commands.
There you can also find information how to get JBang installed, and after that install the Camel app in JBang.
camel-file component has been optimized on the consumer scanning for files, to lazy evaluate file size/modification, which often yields better performance, as file filtering is usually only based on file names.
When querying from salesforce, Camel can now sniff the query result and detect the correct DTO class to use for deserializing the response, alleviating the need to provide sObjectClass and sObjectName options.
It is now possible to inline routes in Rest DSL which means that a Rest service corresponds to 1 route, and not 2 as before. This requires to enable
inline-routes=true in Rest configuration, and to link the routes using
We have upgraded to
TLSv1.3 as default in all components that are using SSL/TLS.
Load properties from vault/secrets cloud services
In 3.19.0, we introduced the feature of automatically reloading context on Secrets update events on Cloud Services.
We currently support this for AWS Secrets Manager, Google Secret Manager and Azure Key Vault.
The features are using some of the services provided on the cloud
- For AWS, we’re leveraging AWS Cloudtrail
- For GCP, we’re leveraging Google Pubsub
- For Azure Key Vault, we’re leveraging Azure Eventgrid and Azure Eventhubs
We provide some Examples in our camel-examples repository.
NOTE: The context reloading feature is implemented as general functionality, which means, that its possible to use for other use-cases.
We upgraded to Kafka Clients 3.2.x. Various other improvements and bug fixes as well, such as better error messages with health checks.
We migrated the external HTTP client used by this component to the HTTP client provided by the JVM.
There are 5 new components:
camel-aws-cloudtrail- Consume events from Amazon Cloudtrail
camel-elasticsearch- Send requests to ElasticSearch via Java Client API
camel-hyperledger-aries- Camel support for Hyperledger Aries
camel-mapstruct- Type Conversion using Mapstruct
camel-python- To use python scripts
We have upgraded to the latest Spring Boot 2.7 release.
Camel Spring Boot now supports
platform-http to make it easy to define Camel routes that start from the embedded HTTP server inside Spring Boot.
Make sure to read the upgrade guide if you are upgrading from a previous Camel version.
