--------------------------------------
Summary: allow for per-route configuration of streamCaching in YAML
Key: CAMEL-18366
URL: https://issues.apache.org/jira/browse/CAMEL-18366
Project: Camel
Issue Type: Improvement
Components: camel-yaml-dsl
Reporter: Bruno Meseguer
Attachments: stage1-gitter-jira.tar.gz
Some Web services are designed with HTTP streaming in mind, you invoke them,
and they maintain the connection open to send back chunks of data at different
time intervals.
An example API of such kind is the following:
[https://developer.gitter.im/docs/streaming-api]
To define a Source Kamelet that consumes messages from such API, Camel's YAML
DSL requires the ability to configure the Route option streamCache that is
enabled by default and requires to be disabled for this use case.
A workaround to make the Kamelet work is to include the global parameter
{code:java}
camel.main.streamCachingEnabled{code}
Using the workaround however is requiring from the user to include it along
with its KameletBinding definition, which is not ideal, specially for non-Camel
users.
Find attached an example KameletBinding making use of an example Kamelet
consuming data from the Streaming API above.
Please note how the global parameter is included. When removing the global
parameter Camel get's stuck waiting for a full HTTP response that never
completes because the server maintains the connection open.
