aws-ddbstream://streamtable-name[?options] |
The stream needs to be created prior to it being used.
You can append query options to the URI in the following format, ?options=value&option2=value&...

Name | Default Value | Context | Description |
|---|---|---|---|
| amazonDynamoDbStreamsClient | null | Consumer | Reference to a com.amazonaws.services.kinesis.AmazonDynamoDBStreams in the Registry. |
| maxMessagesPerPoll | 100 | Consumer | Maximum results that will be returned in each poll to the AWS API, Given that the shard iterator is unique to the consumer, changing it shouldn't effect other consumers. |
| iteratorType | LATEST | Consumer | One of trim_horizon, latest, after_sequence_number, or at_sequence_number. See http://docs.aws.amazon.com/dynamodbstreams/latest/APIReference/API_GetShardIterator.html for descriptions of these two iterator types. |
| sequenceNumberProvider | null | Consumer | Either a bean reference to an implementation of org.apache.camel.component.aws.ddbstream.SequenceNumberProvider or a literal string representing a sequence number. The role of this is to determine where in the stream to start when using one of the after_sequence_number, or at_sequence_number iterator types. |

You have to provide the amazonDynamoDbStreamsClient in the Registry with proxies and relevant credentials configured. |
...
It is recommended that the credentials are obtained by using the DefaultAWSCredentialsProviderChain that is the default when creating a new ClientConfiguration instance, however, a different AWSCredentialsProvider can be specified when calling createClient(...).
Coping with Downtime
AWS DynamoDB Streams outage of less than 24 hours
The consumer will resume from the last seen sequence number (as implemented for CAMEL-9515), so you should receive a flood of events in quick succession, as long as the outage did not also include DynamoDB itself.
AWS DynamoDB Streams outage of more than 24 hours
Given that AWS only retain 24 hours worth of changes, you will have missed change events no matter what mitigations are in place.
