Chapter 355. Twitter Streaming Component

streamingType

Required The streaming type to consume.

StreamingType

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

sendEmptyMessageWhenIdle (consumer)

If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead.

false

boolean

type (consumer)

Endpoint type to use. Only streaming supports event type.

polling

EndpointType

distanceMetric (consumer)

Used by the non-stream geography search, to search by radius using the configured metrics. The unit can either be mi for miles, or km for kilometers. You need to configure all the following options: longitude, latitude, radius, and distanceMetric.

km

String

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.

ExchangePattern

extendedMode (consumer)

Used for enabling full text from twitter (eg receive tweets that contains more than 140 characters).

true

boolean

latitude (consumer)

Used by the non-stream geography search to search by latitude. You need to configure all the following options: longitude, latitude, radius, and distanceMetric.

Double

locations (consumer)

Bounding boxes, created by pairs of lat/lons. Can be used for streaming/filter. A pair is defined as lat,lon. And multiple paris can be separated by semi colon.

String

longitude (consumer)

Used by the non-stream geography search to search by longitude. You need to configure all the following options: longitude, latitude, radius, and distanceMetric.

Double

pollStrategy (consumer)

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.

PollingConsumerPoll Strategy

radius (consumer)

Used by the non-stream geography search to search by radius. You need to configure all the following options: longitude, latitude, radius, and distanceMetric.

Double

twitterStream (consumer)

To use a custom instance of TwitterStream

TwitterStream

synchronous (advanced)

Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).

false

boolean

count (filter)

Limiting number of results per page.

5

Integer

filterOld (filter)

Filter out old tweets, that has previously been polled. This state is stored in memory only, and based on last tweet id.

true

boolean

keywords (filter)

Can be used for a streaming filter. Multiple values can be separated with comma.

String

lang (filter)

The lang string ISO_639-1 which will be used for searching

String

numberOfPages (filter)

The number of pages result which you want camel-twitter to consume.

1

Integer

sinceId (filter)

The last tweet id which will be used for pulling the tweets. It is useful when the camel route is restarted after a long running.

1

long

userIds (filter)

To filter by user ids for streaming/filter. Multiple values can be separated by comma.

String

backoffErrorThreshold (scheduler)

The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in.

int

backoffIdleThreshold (scheduler)

The number of subsequent idle polls that should happen before the backoffMultipler should kick-in.

int

backoffMultiplier (scheduler)

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.

int

delay (scheduler)

Milliseconds before the next poll.

30000

long

greedy (scheduler)

If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages.

false

boolean

initialDelay (scheduler)

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).

1000

long

runLoggingLevel (scheduler)

The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that.

TRACE

LoggingLevel

scheduledExecutorService (scheduler)

Allows for configuring a custom/shared thread pool to use for the consumer. By default each consumer has its own single threaded thread pool.

ScheduledExecutor Service

scheduler (scheduler)

To use a cron scheduler from either camel-spring or camel-quartz2 component

none

ScheduledPollConsumer Scheduler

schedulerProperties (scheduler)

To configure additional properties when using a custom scheduler or any of the Quartz2, Spring based scheduler.

Map

startScheduler (scheduler)

Whether the scheduler should be auto started.

true

boolean

timeUnit (scheduler)

Time unit for initialDelay and delay options.

MILLISECONDS

TimeUnit

useFixedDelay (scheduler)

Controls if fixed delay or fixed rate is used. See ScheduledExecutorService in JDK for details.

true

boolean

sortById (sort)

Sorts by id, so the oldest are first, and newest last.

true

boolean

httpProxyHost (proxy)

The http proxy host which can be used for the camel-twitter. Can also be configured on the TwitterComponent level instead.

String

httpProxyPassword (proxy)

The http proxy password which can be used for the camel-twitter. Can also be configured on the TwitterComponent level instead.

String

httpProxyPort (proxy)

The http proxy port which can be used for the camel-twitter. Can also be configured on the TwitterComponent level instead.

Integer

httpProxyUser (proxy)

The http proxy user which can be used for the camel-twitter. Can also be configured on the TwitterComponent level instead.

String

accessToken (security)

The access token. Can also be configured on the TwitterComponent level instead.

String

accessTokenSecret (security)

The access secret. Can also be configured on the TwitterComponent level instead.

String

consumerKey (security)

The consumer key. Can also be configured on the TwitterComponent level instead.

String

consumerSecret (security)

The consumer secret. Can also be configured on the TwitterComponent level instead.
