API for Amazon SimpleDB v2¶

ABAP Package	`/AWS1/API_SD2`
ABAP SDK "TLA"	`SD2`
ABAP Interface	`/AWS1/IF_SD2`

The "TLA" is a Three Letter Abbreviation that appears in ABAP class names, data dictionary objects and other ABAP objects throughout the AWS SDK for SAP ABAP. The TLA for Amazon SimpleDB v2 is SD2. This TLA helps squeeze ABAP objects into the 30-character length limit of the ABAP data dictionary.

Installation¶

To install the AWS SDK for SAP ABAP, import the Core transport, along with the transport for the SimpleDBv2 module and other API modules you are interested in. A few modules are included in the Core transport itself. For more information, see the Developer Guide guide.

About The Service¶

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.

Using the SDK¶

In your code, create a client using the SDK module for Amazon SimpleDB v2, which is created with factory method /AWS1/CL_SD2_FACTORY=>create(). In this example we will assume you have configured an SDK profile in transaction /AWS1/IMG called ZFINANCE.

DATA(go_session)   = /aws1/cl_rt_session_aws=>create( 'ZFINANCE' ).
DATA(go_sd2)       = /aws1/cl_sd2_factory=>create( go_session ).

Your variable go_sd2 is an instance of /AWS1/IF_SD2, and all of the operations in the Amazon SimpleDB v2 service are accessed by calling methods in /AWS1/IF_SD2.

API Operations¶

For an overview of ABAP method calls corresponding to API operations in Amazon SimpleDB v2, see the Operation List.

Factory Method¶

`/AWS1/CL_SD2_FACTORY=>create( )`¶

Creates an object of type /AWS1/IF_SD2.

IMPORTING¶

Optional arguments:¶

`iv_protocol` `TYPE /aws1/rt_protocol` `/AWS1/RT_PROTOCOL`¶

`io_session` `TYPE REF TO /aws1/cl_rt_session_base` `/AWS1/CL_RT_SESSION_BASE`¶

`iv_region` `TYPE /aws1/rt_region_id` `/AWS1/RT_REGION_ID`¶

`iv_custom_endpoint` `TYPE /aws1/rt_endpoint` `/AWS1/RT_ENDPOINT`¶

RETURNING¶

`oo_client` `TYPE REF TO /aws1/if_sd2` `/AWS1/IF_SD2`¶

/AWS1/IF_SD2 represents the ABAP client for the SimpleDBv2 service, representing each operation as a method call. For more information see the API Page page.

Configuring Programmatically¶

DATA(lo_config) = DATA(go_sd2)->get_config( ).

lo_config is a variable of type /AWS1/CL_SD2_CONFIG. See the documentation for /AWS1/CL_SD2_CONFIG for details on the settings that can be configured.

Waiters¶

Waiters for Implementation can be accessed via get_waiter() method followed by the waiter method to be called.

Details about the waiter methods available for service Implementation can be found in interface /AWS1/IF_SD2_WAITER.

Paginators¶

Paginators for Amazon SimpleDB v2 can be created via get_paginator() which returns a paginator object of type /AWS1/IF_SD2_PAGINATOR. The operation method that is being paginated is called using the paginator object, which accepts any necessary parameters to provide to the underlying API operation. This returns an iterator object which can be used to iterate over paginated results using has_next() and get_next() methods.

Details about the paginator methods available for service Amazon SimpleDB v2 can be found in interface /AWS1/IF_SD2_PAGINATOR.
