Ignite Cache

Since Camel 2.17

Both producer and consumer are supported

The Ignite Cache endpoint is one of camel-ignite endpoints which allows you to interact with an Ignite Cache. This offers both a Producer (to invoke cache operations on an Ignite cache) and a Consumer (to consume changes from a continuous query).

The cache value is always the body of the message, whereas the cache key is always stored in the IgniteConstants.IGNITE_CACHE_KEY message header.

Even if you configure a fixed operation in the endpoint URI, you can vary it per-exchange by setting the IgniteConstants.IGNITE_CACHE_OPERATION message header.

Options

The Ignite Cache component supports 6 options, which are listed below.

Name Description Default Type

configurationResource (common)

Resource from where to load configuration.

Object

ignite (common)

Ignite instance.

Ignite

igniteConfiguration (common)

Ignite configuration.

IgniteConfiguration

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

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

basicPropertyBinding (advanced)

Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

The Ignite Cache endpoint is configured using URI syntax:

ignite-cache:cacheName

with the following path and query parameters:

Path Parameters (1 parameters):

Name Description Default Type

cacheName

Required The cache name.

String

Query Parameters (18 parameters):

Name Description Default Type

propagateIncomingBodyIfNo ReturnValue (common)

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

true

boolean

treatCollectionsAsCacheObjects (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. Default value notice: ContinuousQuery.DFLT_AUTO_UNSUBSCRIBE

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. Default value notice: ContinuousQuery.DFLT_PAGE_SIZE

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.

CacheEntryEventSerializableFilter

timeInterval (consumer)

The time interval for the Continuous Query Consumer. Default value notice: ContinuousQuery.DFLT_TIME_INTERVAL

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. The value can be one of: InOnly, InOut, InOptionalOut

ExchangePattern

cachePeekMode (producer)

The CachePeekMode, only needed for operations that require it (IgniteCacheOperation#SIZE). The value can be one of: ALL, NEAR, PRIMARY, BACKUP, ONHEAP, OFFHEAP

ALL

CachePeekMode

failIfInexistentCache (producer)

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

false

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

operation (producer)

The cache operation to invoke. Possible values: GET, PUT, REMOVE, SIZE, REBALANCE, QUERY, CLEAR. The value can be one of: GET, PUT, REMOVE, SIZE, REBALANCE, QUERY, CLEAR

IgniteCacheOperation

basicPropertyBinding (advanced)

Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

synchronous (advanced)

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

false

boolean

Headers used

This endpoint uses the following headers:

Header name Constant Expected type Description

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).

Spring Boot Auto-Configuration

When using ignite with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-ignite-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 44 options, which are listed below.
