------------------------------------
Summary: Add processor to immediately handle exception while in
retry loop
Key: CAMEL-9069
URL: https://issues.apache.org/jira/browse/CAMEL-9069
Project: Camel
Issue Type: Improvement
Components: camel-core
Reporter: Kevin Telford
Priority: Trivial
We have a recipientList of http4 endpoints. Occasionally an endpoint won't be
available, and will return an exception (whether a ConnectException, or any
other ex and a status code of >=400). To handle these errors we can use a
defaultErrorHandler or leverage onException, and setup redelivery. What we then
would like to do is some custom error handling on each occurrence of an
exception.
Both the defaultErrorHandler and onException support .onRedelivery(). While
this is nice, when a retry delay grows large enough the lag between the
exception and the .onRedelivery() call really begins to grow and so our custom
error handling isn't as much “on error” as it is “on error and after a wait”.
onException also supports a .process() call, however this only occurs once all
redeliveries have failed.
What would be ideal would be an additional .onExceptionOccur(Processor
processor) method (or some such name) that allows for immediate processing upon
an exception, even if its being handled within a retry loop.
