Chapter 156. Ignite Cache Component

cacheName

Required The cache name.

String

propagateIncomingBodyIfNo ReturnValue (common)

Sets whether to propagate the incoming body if the return type of the underlying Ignite operation is void.

true

boolean

treatCollectionsAsCache Objects (common)

Sets whether to treat Collections as cache objects or as Collections of items to insert/update/compute, etc.

false

boolean

autoUnsubscribe (consumer)

Whether auto unsubscribe is enabled in the Continuous Query Consumer.

true

boolean

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

fireExistingQueryResults (consumer)

Whether to process existing results that match the query. Used on initialization of the Continuous Query Consumer.

false

boolean

oneExchangePerUpdate (consumer)

Whether to pack each update in an individual Exchange, even if multiple updates are received in one batch. Only used by the Continuous Query Consumer.

true

boolean

pageSize (consumer)

The page size. Only used by the Continuous Query Consumer.

1

int

query (consumer)

The Query to execute, only needed for operations that require it, and for the Continuous Query Consumer.

Query

remoteFilter (consumer)

The remote filter, only used by the Continuous Query Consumer.

CacheEntryEvent SerializableFilter

timeInterval (consumer)

The time interval for the Continuous Query Consumer.

0

long

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

cachePeekMode (producer)

The CachePeekMode, only needed for operations that require it (IgniteCacheOperation#SIZE).

ALL

CachePeekMode

failIfInexistentCache (producer)

Whether to fail the initialization if the cache doesn’t exist.

false

boolean

operation (producer)

The cache operation to invoke. Possible values: GET, PUT, REMOVE, SIZE, REBALANCE, QUERY, CLEAR.

IgniteCacheOperation

synchronous (advanced)

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

false

boolean

CamelIgniteCacheKey

IgniteConstants.IGNITE_CACHE_KEY

String

The cache key for the entry value in the message body.

CamelIgniteCacheQuery

IgniteConstants.IGNITE_CACHE_QUERY

Query

The query to run (producer) when invoking the QUERY operation.

CamelIgniteCacheOperation

IgniteConstants.IGNITE_CACHE_OPERATION

IgniteCacheOperation enum

Allows you to dynamically change the cache operation to execute (producer).

CamelIgniteCachePeekMode

IgniteConstants.IGNITE_CACHE_PEEK_MODE

CachePeekMode enum

Allows you to dynamically change the cache peek mode when running the SIZE operation.

CamelIgniteCacheEventType

IgniteConstants.IGNITE_CACHE_EVENT_TYPE

int (EventType constants)

This header carries the received event type when using the continuous query consumer.

CamelIgniteCacheName

IgniteConstants.IGNITE_CACHE_NAME

String

This header carries the cache name for which a continuous query event was received (consumer). It does not allow you to dynamically change the cache against which a producer operation is performed. Use EIPs for that (e.g. recipient list, dynamic router).

CamelIgniteCacheOldValue

IgniteConstants.IGNITE_CACHE_OLD_VALUE

Object

This header carries the old cache value when passed in the incoming cache event (consumer).
