camel-aws-s3-kafka-connector source configuration

When using camel-aws-s3-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-aws-s3-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.awss3.CamelAwss3SourceConnector

The camel-aws-s3 source connector supports 77 options, which are listed below.

Setting the autocreation of the bucket

true

MEDIUM

camel.source.endpoint.endpointConfiguration

Amazon AWS Endpoint Configuration

null

MEDIUM

camel.source.endpoint.pathStyleAccess

Whether or not the S3 client should use path style access

false

MEDIUM

camel.source.endpoint.policy

null

MEDIUM

camel.source.endpoint.proxyHost

To define a proxy host when instantiating the S3 client

null

MEDIUM

camel.source.endpoint.proxyPort

Specify a proxy port to be used inside the client definition.

null

MEDIUM

camel.source.endpoint.proxyProtocol

To define a proxy protocol when instantiating the S3 client One of: [HTTP] [HTTPS]

"HTTPS"

MEDIUM

camel.source.endpoint.region

The region in which S3 client needs to work. When using this parameter, the configuration will expect the capitalized name of the region (for example AP_EAST_1) You’ll need to use the name Regions.EU_WEST_1.name()

null

MEDIUM

camel.source.endpoint.useIAMCredentials

Set whether the S3 client should expect to load credentials on an EC2 instance or to expect static credentials to be passed in.

false

MEDIUM

camel.source.endpoint.encryptionMaterials

The encryption materials to use in case of Symmetric/Asymmetric client usage

null

MEDIUM

camel.source.endpoint.useEncryption

Define if encryption must be used or not

false

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.deleteAfterRead

Delete objects from S3 after they have been retrieved. The delete is only performed if the Exchange is committed. If a rollback occurs, the object is not deleted. If this option is false, then the same objects will be retrieve over and over again on the polls. Therefore you need to use the Idempotent Consumer EIP in the route to filter out duplicates. You can filter using the S3Constants#BUCKET_NAME and S3Constants#KEY headers, or only the S3Constants#KEY header.

true

MEDIUM

camel.source.endpoint.delimiter

The delimiter which is used in the com.amazonaws.services.s3.model.ListObjectsRequest to only consume objects we are interested in.

null

MEDIUM

camel.source.endpoint.fileName

To get the object from the bucket with the given file name

null

MEDIUM

camel.source.endpoint.includeBody

If it is true, the exchange body will be set to a stream to the contents of the file. If false, the headers will be set with the S3 object metadata, but the body will be null. This option is strongly related to autocloseBody option. In case of setting includeBody to true and autocloseBody to false, it will be up to the caller to close the S3Object stream. Setting autocloseBody to true, will close the S3Object stream automatically.

true

MEDIUM

camel.source.endpoint.maxConnections

Set the maxConnections parameter in the S3 client configuration

60

MEDIUM

camel.source.endpoint.maxMessagesPerPoll

Gets the maximum number of messages as a limit to poll at each polling. Gets the maximum number of messages as a limit to poll at each polling. The default value is 10. Use 0 or a negative number to set it as unlimited.

MEDIUM

camel.source.endpoint.prefix

The prefix which is used in the com.amazonaws.services.s3.model.ListObjectsRequest to only consume objects we are interested in.

null

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

MEDIUM

camel.source.endpoint.autocloseBody

If this option is true and includeBody is true, then the S3Object.close() method will be called on exchange completion. This option is strongly related to includeBody option. In case of setting includeBody to true and autocloseBody to false, it will be up to the caller to close the S3Object stream. Setting autocloseBody to true, will close the S3Object stream automatically.

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.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

MEDIUM

camel.source.endpoint.delay
