camel-mybatis-kafka-connector source configuration

Connector description: Performs a query, poll, insert, update or delete in a relational database using MyBatis.

When using camel-mybatis-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-mybatis-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.mybatis.CamelMybatisSourceConnector

The camel-mybatis source connector supports 30 options, which are listed below.

Name Description Default Required Priority

camel.source.path.statement

The statement name in the MyBatis XML mapping file which maps to the query, insert, update or delete operation you wish to evaluate.

null

true

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

false

MEDIUM

camel.source.endpoint.maxMessagesPerPoll

This option is intended to split results returned by the database pool into the batches and deliver them in multiple exchanges. This integer defines the maximum messages to deliver in single exchange. By default, no maximum is set. Can be used to set a limit of e.g. 1000 to avoid when starting up the server that there are thousands of files. Set a value of 0 or negative to disable it.

0

false

MEDIUM

camel.source.endpoint.onConsume

Statement to run after data has been processed in the route

null

false

MEDIUM

camel.source.endpoint.routeEmptyResultSet

Whether allow empty resultset to be routed to the next hop

false

false

MEDIUM

camel.source.endpoint.sendEmptyMessageWhenIdle

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

false

false

MEDIUM

camel.source.endpoint.transacted

Enables or disables transaction. If enabled then if processing an exchange failed then the consumer breaks out processing any further exchanges to cause a rollback eager.

false

false

MEDIUM

camel.source.endpoint.useIterator

Process resultset individually or as a list

true

false

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.

null

false

MEDIUM

camel.source.endpoint.exchangePattern

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

null

false

MEDIUM

camel.source.endpoint.pollStrategy

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.

null

false

MEDIUM

camel.source.endpoint.processingStrategy

To use a custom MyBatisProcessingStrategy

null

false

MEDIUM

camel.source.endpoint.backoffErrorThreshold

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

null

false

MEDIUM

camel.source.endpoint.backoffIdleThreshold

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

null

false

MEDIUM

camel.source.endpoint.backoffMultiplier

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.

null

false

MEDIUM

camel.source.endpoint.delay

Milliseconds before the next poll.

500L

false

MEDIUM

camel.source.endpoint.greedy

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

false

false

MEDIUM

camel.source.endpoint.initialDelay

Milliseconds before the first poll starts.

1000L

false

MEDIUM

camel.source.endpoint.repeatCount

Specifies a maximum limit of number of fires. So if you set it to 1, the scheduler will only fire once. If you set it to 5, it will only fire five times. A value of zero or negative means fire forever.

0L

false

MEDIUM

camel.source.endpoint.runLoggingLevel

The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that. One of: [TRACE] [DEBUG] [INFO] [WARN] [ERROR] [OFF]

"TRACE"

false

MEDIUM

camel.source.endpoint.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.

null

false

MEDIUM

camel.source.endpoint.startScheduler

Whether the scheduler should be auto started.

true

false

MEDIUM

camel.source.endpoint.timeUnit

Time unit for initialDelay and delay options. One of: [NANOSECONDS] [MICROSECONDS] [MILLISECONDS] [SECONDS] [MINUTES] [HOURS] [DAYS]

"MILLISECONDS"

false

MEDIUM

camel.source.endpoint.useFixedDelay

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

true

false

MEDIUM

camel.component.mybatis.configurationUri

Location of MyBatis xml configuration file. The default value is: SqlMapConfig.xml loaded from the classpath

"SqlMapConfig.xml"

false

MEDIUM

camel.component.mybatis.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

false

camel.component.mybatis.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.
