camel-file-watch-kafka-connector source configuration

When using camel-file-watch-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-file-watch-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.filewatch.CamelFilewatchSourceConnector

The camel-file-watch source connector supports 22 options, which are listed below.

Name Description Default Priority

camel.source.path.path

Path of directory to consume events from.

null

HIGH

camel.source.endpoint.antInclude

ANT style pattern to match files. The file is matched against path relative to endpoint path. Pattern must be also relative (not starting with slash)

"**"

MEDIUM

camel.source.endpoint.autoCreate

Auto create directory if does not exists.

true

MEDIUM

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.concurrentConsumers

The number of concurrent consumers. Increase this value, if your route is slow to prevent buffering in queue.

1

MEDIUM

camel.source.endpoint.events

Comma separated list of events to watch. One of: [CREATE] [MODIFY] [DELETE]

"CREATE,MODIFY,DELETE"

MEDIUM

camel.source.endpoint.fileHasher

Reference to io.methvin.watcher.hashing.FileHasher. This prevents emitting duplicate events on some platforms. For working with large files and if you dont need detect multiple modifications per second per file, use #lastModifiedTimeFileHasher. You can also provide custom implementation in registry.

"#murmur3FFileHasher"

MEDIUM

camel.source.endpoint.pollThreads

The number of threads polling WatchService. Increase this value, if you see OVERFLOW messages in log.

1

MEDIUM

camel.source.endpoint.queueSize

Maximum size of queue between WatchService and consumer. Unbounded by default.

2147483647

MEDIUM

camel.source.endpoint.recursive

Watch recursive in current and child directories (including newly created directories).

true

MEDIUM

camel.source.endpoint.useFileHashing

Enables or disables file hashing to detect duplicate events. If you disable this, you can get some events multiple times on some platforms and JDKs. Check java.nio.file.WatchService limitations for your target platform.

true

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

MEDIUM

camel.source.endpoint.exchangePattern

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

null

MEDIUM

camel.source.endpoint.basicPropertyBinding

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

false

MEDIUM

camel.source.endpoint.synchronous

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

false

MEDIUM

camel.component.file-watch.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.component.file-watch.concurrentConsumers

The number of concurrent consumers. Increase this value, if your route is slow to prevent buffering in queue.

1

MEDIUM

For working with large files and if you dont need detect multiple modifications per second per file, use #lastModifiedTimeFileHasher. You can also provide custom implementation in registry.

false
