| 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
| *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

+= Apache Camel 3.x Upgrade Guide
+
+This document is for helping you upgrade your Apache Camel application
+from Camel 3.x to 3.y. For example if you are upgrading Camel 3.0 to 3.2, then you should follow the guides
+from both 3.0 to 3.1 and 3.1 to 3.2.
+
+== Upgrading Camel 3.9 to 3.10
+
+=== camel-scheduler
+
+The option `concurrentTasks` has been renamed to `poolSize` to better reflect its purpose.
+The scheduler has also been fixed to only schedule triggering by one, and not as mistakenly by causing
+concurrent triggering which causes routing mistakes.
+
+The option configures the pool size of the scheduled thread pool used by the scheduler.
+
+If the scheduler thread is being blocked by anywhere in the downstream routing, and you want the scheduler
+to schedule with a fixed interval, you can use the Threads EIP as queue for pending tasks.
