Chapter 33. AWS SimpleDB Component Available as of Camel version 2.9 The sdb component supports storing and retrieving data from/to Amazon's SDB service. Prerequisites You must have a valid Amazon Web Services developer account, and be signed up to use Amazon SDB. More information are available at Amazon SDB . 33.1. URI Format aws-sdb://domainName[?options] You can append query options to the URI in the following format, ?options=value&option2=value&... 33.2. URI Options The AWS SimpleDB component has no options. The AWS SimpleDB endpoint is configured using URI syntax: with the following path and query parameters: 33.2.1. Path Parameters (1 parameters): Name Description Default Type domainName Required The name of the domain currently worked with. String 33.2.2. Query Parameters (10 parameters): Name Description Default Type accessKey (producer) Amazon AWS Access Key String amazonSDBClient (producer) To use the AmazonSimpleDB as the client AmazonSimpleDB consistentRead (producer) Determines whether or not strong consistency should be enforced when data is read. false boolean maxNumberOfDomains (producer) The maximum number of domain names you want returned. The range is 1 to 100. Integer operation (producer) Operation to perform PutAttributes SdbOperations proxyHost (producer) To define a proxy host when instantiating the SDB client String proxyPort (producer) To define a proxy port when instantiating the SDB client Integer region (producer) The region in which SDB client needs to work String secretKey (producer) Amazon AWS Secret Key String synchronous (advanced) Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). false boolean 33.3. Spring Boot Auto-Configuration The component supports 2 options, which are listed below. Name Description Default Type camel.component.aws-sdb.enabled Enable aws-sdb component true Boolean camel.component.aws-sdb.resolve-property-placeholders Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. true Boolean Required SDB component options You have to provide the amazonSDBClient in the Registry or your accessKey and secretKey to access the Amazon's SDB . 33.4. Usage 33.4.1. Message headers evaluated by the SDB producer Header Type Description CamelAwsSdbAttributes Collection<Attribute> List of attributes to be acted upon. CamelAwsSdbAttributeNames Collection<String> The names of the attributes to be retrieved. CamelAwsSdbConsistentRead Boolean Determines whether or not strong consistency should be enforced when data is read. CamelAwsSdbDeletableItems Collection<DeletableItem> A list of items on which to perform the delete operation in a batch. CamelAwsSdbDomainName String The name of the domain currently worked with. CamelAwsSdbItemName String The unique key for this item CamelAwsSdbMaxNumberOfDomains Integer The maximum number of domain names you want returned. The range is 1 * to 100. CamelAwsSdbNextToken String A string specifying where to start the list of domain/item names. CamelAwsSdbOperation String To override the operation from the URI options. CamelAwsSdbReplaceableAttributes Collection<ReplaceableAttribute> List of attributes to put in an Item. CamelAwsSdbReplaceableItems Collection<ReplaceableItem> A list of items to put in a Domain. CamelAwsSdbSelectExpression String The expression used to query the domain. CamelAwsSdbUpdateCondition UpdateCondition The update condition which, if specified, determines whether the specified attributes will be updated/deleted or not. 33.4.2. Message headers set during DomainMetadata operation Header Type Description CamelAwsSdbTimestamp Integer The data and time when metadata was calculated, in Epoch (UNIX) seconds. CamelAwsSdbItemCount Integer The number of all items in the domain. CamelAwsSdbAttributeNameCount Integer The number of unique attribute names in the domain. CamelAwsSdbAttributeValueCount Integer The number of all attribute name/value pairs in the domain. CamelAwsSdbAttributeNameSize Long The total size of all unique attribute names in the domain, in bytes. CamelAwsSdbAttributeValueSize Long The total size of all attribute values in the domain, in bytes. CamelAwsSdbItemNameSize Long The total size of all item names in the domain, in bytes. 33.4.3. Message headers set during GetAttributes operation Header Type Description CamelAwsSdbAttributes List<Attribute> The list of attributes returned by the operation. 33.4.4. Message headers set during ListDomains operation Header Type Description CamelAwsSdbDomainNames List<String> A list of domain names that match the expression. CamelAwsSdbNextToken String An opaque token indicating that there are more domains than the specified MaxNumberOfDomains still available. 33.4.5. Message headers set during Select operation Header Type Description CamelAwsSdbItems List<Item> A list of items that match the select expression. CamelAwsSdbNextToken String An opaque token indicating that more items than MaxNumberOfItems were matched, the response size exceeded 1 megabyte, or the execution time exceeded 5 seconds. 33.4.6. Advanced AmazonSimpleDB configuration If you need more control over the AmazonSimpleDB instance configuration you can create your own instance and refer to it from the URI: from("direct:start") .to("aws-sdb://domainName?amazonSDBClient=#client"); The #client refers to a AmazonSimpleDB in the Registry. For example if your Camel Application is running behind a firewall: AWSCredentials awsCredentials = new BasicAWSCredentials("myAccessKey", "mySecretKey"); ClientConfiguration clientConfiguration = new ClientConfiguration(); clientConfiguration.setProxyHost("http://myProxyHost"); clientConfiguration.setProxyPort(8080); AmazonSimpleDB client = new AmazonSimpleDBClient(awsCredentials, clientConfiguration); registry.bind("client", client); 33.5. Dependencies Maven users will need to add the following dependency to their pom.xml. pom.xml <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-aws</artifactId> <version>USD{camel-version}</version> </dependency> where USD{camel-version } must be replaced by the actual version of Camel (2.8.4 or higher). 33.6.

aws-sdb:domainName
from("direct:start") .to("aws-sdb://domainName?amazonSDBClient=#client");
AWSCredentials awsCredentials = new BasicAWSCredentials("myAccessKey", "mySecretKey"); ClientConfiguration clientConfiguration = new ClientConfiguration(); clientConfiguration.setProxyHost("http://myProxyHost"); clientConfiguration.setProxyPort(8080); AmazonSimpleDB client = new AmazonSimpleDBClient(awsCredentials, clientConfiguration); registry.bind("client", client);
