Overrides the default endpoint for this client ("sdb.amazonaws.com").
|
void |
setRegion(Region region)
An alternative to
AmazonSimpleDB.setEndpoint(String), sets the regional endpoint for this client's
service calls. |
public void setEndpoint(String endpoint)
AmazonSimpleDB
Callers can pass in just the endpoint (ex: "sdb.amazonaws.com") or a full URL, including the protocol (ex:
"sdb.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's
ClientConfiguration will be used, which by default is HTTPS.
For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/java-dg-region-selection.html#region-selection- choose-endpoint
This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

the region specific AWS endpoint this client will communicate with.public void setRegion(Region region)
AmazonSimpleDBAmazonSimpleDB.setEndpoint(String), sets the regional endpoint for this client's
service calls. Callers can use this method to control which AWS region they want to work with.
By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the
ClientConfiguration supplied at construction.
This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

Region.isServiceSupported(String)public BatchDeleteAttributesResult batchDeleteAttributes(BatchDeleteAttributesRequest request)
AmazonSimpleDBPerforms multiple DeleteAttributes operations in a single call, which reduces round trips and latencies. This enables Amazon SimpleDB to optimize requests, which generally yields better throughput.
The following limitations are enforced for this operation:
batchDeleteAttributes in interface AmazonSimpleDBpublic BatchPutAttributesResult batchPutAttributes(BatchPutAttributesRequest request)
AmazonSimpleDB
The BatchPutAttributes operation creates or replaces attributes within one or more items. By using
this operation, the client can perform multiple PutAttribute operation with a single call. This helps
yield savings in round trips and latencies, enabling Amazon SimpleDB to optimize requests and generally produce
better throughput.
The client may specify the item name with the Item.X.ItemName parameter. The client may specify new
attributes using a combination of the Item.X.Attribute.Y.Name and
Item.X.Attribute.Y.Value parameters. The client may specify the first attribute for the first item
using the parameters Item.0.Attribute.0.Name and Item.0.Attribute.0.Value, and for the
second attribute for the first item by the parameters Item.0.Attribute.1.Name and
Item.0.Attribute.1.Value, and so on.
Attributes are uniquely identified within an item by their name/value combination. For example, a single item can
have the attributes { "first_name", "first_value" } and
{ "first_name", "second_value" }. However, it cannot have two attribute instances where both the
Item.X.Attribute.Y.Name and Item.X.Attribute.Y.Value are the same.
Optionally, the requester can supply the Replace parameter for each individual value. Setting this
value to true will cause the new attribute values to replace the existing attribute values. For
example, if an item I has the attributes { 'a', '1' }, { 'b', '2'} and
{ 'b', '3' } and the requester does a BatchPutAttributes of {'I', 'b', '4' } with the
Replace parameter set to true, the final attributes of the item will be { 'a', '1' } and
{ 'b', '4' }, replacing the previous values of the 'b' attribute with the new value.
Expected.X.Name,
Expected.X.Value, or Expected.X.Exists.
You can execute multiple BatchPutAttributes operations and other operations in parallel. However,
large numbers of concurrent BatchPutAttributes calls can result in Service Unavailable (503)
responses.
The following limitations are enforced for this operation:
BatchPutAttributes operationbatchPutAttributes in interface AmazonSimpleDBpublic CreateDomainResult createDomain(CreateDomainRequest request)
AmazonSimpleDB
The CreateDomain operation creates a new domain. The domain name should be unique among the domains
associated with the Access Key ID provided in the request. The CreateDomain operation may take 10 or
more seconds to complete.
The client can create up to 100 domains per account.
If the client requires additional domains, go to http://aws.amazon.com/contact-us/simpledb-limit-request/.
createDomain in interface AmazonSimpleDBpublic DeleteAttributesResult deleteAttributes(DeleteAttributesRequest request)
AmazonSimpleDBDeletes one or more attributes associated with an item. If all attributes of the item are deleted, the item is deleted.
DeleteAttributes is an idempotent operation; running it multiple times on the same item or attribute
does not result in an error response.
Because Amazon SimpleDB makes multiple copies of item data and uses an eventual consistency update model,
performing a GetAttributes or Select operation (read) immediately after a
DeleteAttributes or PutAttributes operation (write) might not return updated item data.
deleteAttributes in interface AmazonSimpleDBpublic DeleteDomainResult deleteDomain(DeleteDomainRequest request)
AmazonSimpleDB
The DeleteDomain operation deletes a domain. Any items (and their attributes) in the domain are
deleted as well. The DeleteDomain operation might take 10 or more seconds to complete.
deleteDomain in interface AmazonSimpleDBpublic DomainMetadataResult domainMetadata(DomainMetadataRequest request)
AmazonSimpleDBReturns information about the domain, including when the domain was created, the number of items and attributes in the domain, and the size of the attribute names and values.
domainMetadata in interface AmazonSimpleDBpublic GetAttributesResult getAttributes(GetAttributesRequest request)
AmazonSimpleDBReturns all of the attributes associated with the specified item. Optionally, the attributes returned can be limited to one or more attributes by specifying an attribute name parameter.
If the item does not exist on the replica that was accessed for this operation, an empty set is returned. The system does not return an error as it cannot guarantee the item does not exist on other replicas.
getAttributes in interface AmazonSimpleDBpublic ListDomainsResult listDomains(ListDomainsRequest request)
AmazonSimpleDB
The ListDomains operation lists all domains associated with the Access Key ID. It returns domain
names up to the limit set by MaxNumberOfDomains. A NextToken is returned if there are more than MaxNumberOfDomains domains.
Calling ListDomains successive times with the NextToken provided by the operation
returns up to MaxNumberOfDomains more domain names with each successive operation call.
listDomains in interface AmazonSimpleDBpublic ListDomainsResult listDomains()
AmazonSimpleDBlistDomains in interface AmazonSimpleDBAmazonSimpleDB.listDomains(ListDomainsRequest)public PutAttributesResult putAttributes(PutAttributesRequest request)
AmazonSimpleDB
The PutAttributes operation creates or replaces attributes in an item. The client may specify new attributes
using a combination of the Attribute.X.Name and Attribute.X.Value parameters. The
client specifies the first attribute by the parameters Attribute.0.Name and
Attribute.0.Value, the second attribute by the parameters Attribute.1.Name and
Attribute.1.Value, and so on.
Attributes are uniquely identified in an item by their name/value combination. For example, a single item can
have the attributes { "first_name", "first_value" } and { "first_name", second_value" }
. However, it cannot have two attribute instances where both the Attribute.X.Name and
Attribute.X.Value are the same.
Optionally, the requestor can supply the Replace parameter for each individual attribute. Setting
this value to true causes the new attribute value to replace the existing attribute value(s). For
example, if an item has the attributes { 'a', '1' }, { 'b', '2'} and
{ 'b', '3' } and the requestor calls PutAttributes using the attributes
{ 'b', '4' } with the Replace parameter set to true, the final attributes of the item
are changed to { 'a', '1' } and { 'b', '4' }, which replaces the previous values of the
'b' attribute with the new value.
You cannot specify an empty string as an attribute name.
Because Amazon SimpleDB makes multiple copies of client data and uses an eventual consistency update model, an immediate GetAttributes or Select operation (read) immediately after a PutAttributes or DeleteAttributes operation (write) might not return the updated data.
The following limitations are enforced for this operation:
putAttributes in interface AmazonSimpleDBpublic SelectResult select(SelectRequest request)
AmazonSimpleDB
The Select operation returns a set of attributes for ItemNames that match the select
expression. Select is similar to the standard SQL SELECT statement.
The total size of the response cannot exceed 1 MB in total size. Amazon SimpleDB automatically adjusts the number
of items returned per page to enforce this limit. For example, if the client asks to retrieve 2500 items, but
each individual item is 10 kB in size, the system returns 100 items and an appropriate NextToken so
the client can access the next page of results.
