Etcd Watch
Since Camel 2.18
Only consumer is supported
Since Camel 2.18
The camel Etcd component allows you to work with Etcd, a distributed reliable key-value store.
URI Options
The Etcd Watch component supports 13 options, which are listed below.
| Name | Description | Default | Type |
|---|---|---|---|
bridgeErrorHandler (consumer) |
Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. |

boolean |
configuration (consumer) |
Component configuration. |
