camel-corda-kafka-connector source configuration

Connector Description: Perform operations against Corda blockchain platform using corda-rpc library.

When using camel-corda-kafka-connector as source make sure to use the following Maven dependency to have support for the connector:

<dependency>
  <groupId>org.apache.camel.kafkaconnector</groupId>
  <artifactId>camel-corda-kafka-connector</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel Kafka connector version -->
</dependency>

To use this source connector in Kafka connect you’ll need to set the following connector.class

connector.class=org.apache.camel.kafkaconnector.corda.CamelCordaSourceConnector

The camel-corda source connector supports 25 options, which are listed below.

Name Description Default Priority

camel.source.path.node

Required The url for the corda node.

HIGH

camel.source.endpoint.bridgeErrorHandler

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

MEDIUM

camel.source.endpoint.pageSpecification

PageSpecification allows specification of a page number (starting from 1) and page size (defaulting to 200 with a maximum page size of (Integer.MAX_INT) Note: we default the page number to 200 to enable queries without requiring a page specification but enabling detection of large results sets that fall out of the 200 requirement. Max page size should be used with extreme caution as results may exceed your JVM memory footprint.

"200"

MEDIUM

camel.source.endpoint.processSnapshot

Whether to process snapshots or not.

true

MEDIUM

camel.source.endpoint.sort

Sort allows specification of a set of entity attribute names and their associated directionality and null handling, to be applied upon processing a query specification. One of: [ASC] [DESC].

Enum values:

  • ASC

  • DESC

MEDIUM

camel.source.endpoint.contractStateClass

A contract state (or just state) contains opaque data used by a contract program. It can be thought of as a disk file that the program can use to persist data across transactions. States are immutable: once created they are never updated, instead, any changes must generate a new successor state. States can be updated (consumed) only once: the notary is responsible for ensuring there is no double spending by only signing a transaction if the input states are all free.

MEDIUM

camel.source.endpoint.exceptionHandler

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.

MEDIUM

camel.source.endpoint.exchangePattern

Sets the exchange pattern when the consumer creates an exchange. One of: [InOnly] [InOut] [InOptionalOut].

Enum values:

  • InOnly

  • InOut

  • InOptionalOut

MEDIUM

camel.source.endpoint.flowLogicArguments

Start the given flow with the given arguments, returning an Observable with a single observation of the result of running the flow. The flowLogicClass must be annotated with net.corda.core.flows.StartableByRPC.

MEDIUM

camel.source.endpoint.flowLogicClass

Start the given flow with the given arguments, returning an Observable with a single observation of the result of running the flow. The flowLogicClass must be annotated with net.corda.core.flows.StartableByRPC.

MEDIUM

camel.source.endpoint.queryCriteria

QueryCriteria assumes underlying schema tables are correctly indexed for performance.

MEDIUM

camel.source.endpoint.password

Password for login.

MEDIUM

camel.source.endpoint.username

Username for login.

MEDIUM

camel.component.corda.configuration

To use a shared configuration.

MEDIUM

camel.component.corda.bridgeErrorHandler

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.

MEDIUM

camel.component.corda.autowiredEnabled

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.
