+== Options
+
+
+
+// component options: START
+The Kamelet component supports 7 options, which are listed below.
+
+
+
+[width="100%",cols="2,5,^1,2",options="header"]
+|===
+| Name | Description | Default | Type
+| *routeProperties* (common) | Set route local parameters. | | Map
+| *templateProperties* (common) | Set template local parameters. | | Map
+| *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. | false |
boolean
+| *block* (producer) | If sending a message to a kamelet endpoint which has no
active consumer, then we can tell the producer to block and wait for the
consumer to become active. | true | boolean
+| *lazyStartProducer* (producer) | Whether the producer should be started lazy
(on the first message). By starting lazy you can use this to allow CamelContext
and routes to startup in situations where a producer may otherwise fail during
starting and cause the route to fail being started. By deferring this startup
to be lazy then the startup failure can be handled during routing messages via
Camel's routing error handlers. Beware that when the first message is processed
then creating and starting the producer may take a little time and prolong the
total processing time of the processing. | false | boolean
+| *timeout* (producer) | The timeout value to use if block is enabled. | 30000
| long
+| *autowiredEnabled* (advanced) | Whether autowiring is enabled. This is used
for automatic autowiring options (the option must be marked as autowired) by
looking up in the registry to find if there is a single instance of matching
type, which then gets configured on the component. This can be used for
automatic configuring JDBC data sources, JMS connection factories, AWS Clients,
etc. | true | boolean
+|===
+// component options: END
+
+
+
+
+// endpoint options: START
+The Kamelet endpoint is configured using URI syntax:
+
+----
+kamelet:templateId/routeId
+----
+
+with the following path and query parameters:
+
+=== Path Parameters (2 parameters):
+
+
+[width="100%",cols="2,5,^1,2",options="header"]
+|===
+| Name | Description | Default | Type
+| *templateId* | *Required* The Route Template ID | | String
+| *routeId* | The Route ID. Default value notice: The ID will be
auto-generated if not provided | | String
+|===
+
+
+=== Query Parameters (7 parameters):
+
+
+[width="100%",cols="2,5,^1,2",options="header"]
+|===
+| 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. | false |
boolean
+| *exceptionHandler* (consumer) | To let the consumer use a custom
ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this
option is not in use. By default the consumer will deal with exceptions, that
will be logged at WARN or ERROR level and ignored. | | ExceptionHandler
+| *exchangePattern* (consumer) | Sets the exchange pattern when the consumer
creates an exchange. There are 3 enums and the value can be one of: InOnly,
InOut, InOptionalOut | | ExchangePattern
+| *block* (producer) | If sending a message to a direct endpoint which has no
active consumer, then we can tell the producer to block and wait for the
consumer to become active. | true | boolean
+| *failIfNoConsumers* (producer) | Whether the producer should fail by
throwing an exception, when sending to a kamelet endpoint with no active
consumers. | true | boolean
+| *lazyStartProducer* (producer) | Whether the producer should be started lazy
(on the first message). By starting lazy you can use this to allow CamelContext
and routes to startup in situations where a producer may otherwise fail during
starting and cause the route to fail being started. By deferring this startup
to be lazy then the startup failure can be handled during routing messages via
Camel's routing error handlers. Beware that when the first message is processed
then creating and starting the producer may take a little time and prolong the

+| *timeout* (producer) | The timeout value to use if block is enabled. | 30000
| long
+|===
+// endpoint options: END
+
+[NOTE]
+====
+The *kamelet* endpoint is *lenient*, which means that the endpoint accepts
additional parameters that are passed to the ROute Templkate engine and
consumed upon route materialization.
+====
+
+== Samples
+
+
+Kamelets can be used as if they were standard Camel components.
+For example, suppose that we have created a Route Template as follows:
+
+[source,java]
+----
+routeTemplate("setBody")
