Re: What are your Camel Best Practices?

[Bilgin Ibryam <bi...@gmail.com>]

Hi Max,

there is no central place with Camel best practices as most of these are
unwritten code conventions, common sense, or practices followed for the
sake of consistency.

The first one you have identified is correct. Prefixing header names with
component name will prevent headers from being used by other components.

The second is more arguable, as most components expect their main input as
message body even though it may require more work from the developer.

Most of these are non written practices and not written rules as they
should be applied with consideration rather than followed as a rule.

HTH,
