The beanstalk component is used for job retrieval and post-processing of Beanstalk jobs.

Name Kind Group Required Default Type Enum Description
connectionSettings path common java.lang.String Connection settings host:port/tube
command parameter common org.apache.camel.component.beanstalk.BeanstalkCommand bury
release
put
touch
delete
kick
put means to put the job into Beanstalk. Job body is specified in the Camel message body. Job ID will be returned in beanstalk.jobId message header. delete, release, touch or bury expect Job ID in the message header beanstalk.jobId. Result of the operation is returned in beanstalk.result message header kick expects the number of jobs to kick in the message body and returns the number of jobs actually kicked out in the message header beanstalk.result.
jobDelay parameter common 0 int Job delay in seconds.
jobPriority parameter common 1000 long Job priority. (0 is the highest, see Beanstalk protocol)
jobTimeToRun parameter common 60 int Job time to run in seconds. (when 0, the beanstalkd daemon raises it to 1 automatically, see Beanstalk protocol)
awaitJob parameter consumer true boolean Whether to wait for job to complete before ack the job from beanstalk
bridgeErrorHandler parameter consumer boolean 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/ERROR level and ignored.
onFailure parameter consumer org.apache.camel.component.beanstalk.BeanstalkCommand bury
release
put
touch
delete
kick
Command to use when processing failed.
sendEmptyMessageWhenIdle parameter consumer boolean If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead.
useBlockIO parameter consumer true boolean Whether to use blockIO.
exceptionHandler parameter consumer (advanced) org.apache.camel.spi.ExceptionHandler To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this options is not in use. By default the consumer will deal with exceptions, that will be logged at WARN/ERROR level and ignored.
exchangePattern parameter consumer (advanced) org.apache.camel.ExchangePattern InOnly
RobustInOnly
InOut
InOptionalOut
OutOnly
RobustOutOnly
OutIn
OutOptionalIn
Sets the exchange pattern when the consumer creates an exchange.
pollStrategy parameter consumer (advanced) org.apache.camel.spi.PollingConsumerPollStrategy A pluggable org.apache.camel.PollingConsumerPollingStrategy allowing you to provide your custom implementation to control error handling usually occurred during the poll operation before an Exchange have been created and being routed in Camel.
synchronous parameter advanced false boolean Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).
backoffErrorThreshold parameter scheduler int The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in.
backoffIdleThreshold parameter scheduler int The number of subsequent idle polls that should happen before the backoffMultipler should kick-in.
backoffMultiplier parameter scheduler int To let the scheduled polling consumer backoff if there has been a number of subsequent idles/errors in a row. The multiplier is then the number of polls that will be skipped before the next actual attempt is happening again. When this option is in use then backoffIdleThreshold and/or backoffErrorThreshold must also be configured.
delay parameter scheduler 500 long Milliseconds before the next poll. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour).
greedy parameter scheduler boolean If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages.
initialDelay parameter scheduler 1000 long Milliseconds before the first poll starts. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour).
runLoggingLevel parameter scheduler TRACE org.apache.camel.LoggingLevel TRACE
DEBUG
INFO
WARN
ERROR
OFF
The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that.
scheduledExecutorService parameter scheduler java.util.concurrent.ScheduledExecutorService Allows for configuring a custom/shared thread pool to use for the consumer. By default each consumer has its own single threaded thread pool.
scheduler parameter scheduler none org.apache.camel.spi.ScheduledPollConsumerScheduler none
spring
quartz2
To use a cron scheduler from either camel-spring or camel-quartz2 component
schedulerProperties parameter scheduler java.util.Map To configure additional properties when using a custom scheduler or any of the Quartz2, Spring based scheduler.
startScheduler parameter scheduler true boolean Whether the scheduler should be auto started.
timeUnit parameter scheduler MILLISECONDS java.util.concurrent.TimeUnit NANOSECONDS
MICROSECONDS
MILLISECONDS
SECONDS
MINUTES
HOURS
DAYS
Time unit for initialDelay and delay options.
useFixedDelay parameter scheduler true boolean Controls if fixed delay or fixed rate is used. See ScheduledExecutorService in JDK for details.

beanstalk consumer

PollingConsumer to read Beanstalk jobs.

The consumer may delete the job immediately or based on successful {@link Exchange} completion. The behavior is configurable by consumer.awaitJob flag (by default true)

This consumer will add a {@link Synchronization} object to every {@link Exchange} object it creates in order to react on successful exchange completion or failure.

In the case of successful completion, Beanstalk's delete method is called upon the job. In the case of failure the default reaction is to call bury.

The reaction on failures is configurable: possible variants are "bury", "release" or "delete"
