SimpleDB class

Amazon SimpleDB is a web service providing the core database functions of data indexing and querying in the cloud. By offloading the time and effort associated with building and operating a web-scale database, SimpleDB provides developers the freedom to focus on application development. A traditional, clustered relational database requires a sizable upfront capital outlay, is complex to design, and often requires extensive and repetitive database administration. Amazon SimpleDB is dramatically simpler, requiring no schema, automatically indexing your data and providing a simple API for storage and access. This approach eliminates the administrative burden of data modeling, index maintenance, and performance tuning. Developers gain access to this functionality within Amazon's proven computing environment, are able to scale instantly, and pay only for what they use.

Constructors

SimpleDB({required String region, AwsClientCredentials? credentials, AwsClientCredentialsProvider? credentialsProvider, Client? client, String? endpointUrl})

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

shapes → Map<String, Shape>

final

Methods

batchDeleteAttributes({required String domainName, required List<DeletableItem> items}) → Future<void>

Performs 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.

batchPutAttributes({required String domainName, required List<ReplaceableItem> items}) → Future<void>

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.

close() → void

Closes the internal HTTP client if none was provided at creation. If a client was passed as a constructor argument, this becomes a noop.

createDomain({required String domainName}) → Future<void>

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.

deleteAttributes({required String domainName, required String itemName, List<DeletableAttribute>? attributes, UpdateCondition? expected}) → Future<void>

Deletes 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.

deleteDomain({required String domainName}) → Future<void>

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.

domainMetadata({required String domainName}) → Future<DomainMetadataResult>

Returns 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.

getAttributes({required String domainName, required String itemName, List<String>? attributeNames, bool? consistentRead}) → Future<GetAttributesResult>

Returns 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.

listDomains({int? maxNumberOfDomains, String? nextToken}) → Future<ListDomainsResult>

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.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

putAttributes({required List<ReplaceableAttribute> attributes, required String domainName, required String itemName, UpdateCondition? expected}) → Future<void>

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.

select({required String selectExpression, bool? consistentRead, String? nextToken}) → Future<SelectResult>

The Select operation returns a set of attributes for ItemNames that match the select expression. Select is similar to the standard SQL SELECT statement.

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
