/**
* Synchronous and asynchronous client classes for accessing AmazonDynamoDBv2.
*
* Amazon DynamoDB Overview
* This is the Amazon DynamoDB API Reference. This guide provides
* descriptions and samples of the DynamoDB API. For information about
* application development using this API, see the Amazon DynamoDB
* Developer Guide.
*
*
* The following are short descriptions of each API action, organized by
* function.
*
*
* Managing Tables
*
*
*
*
* -
* CreateTable - Creates a table with user-specified provisioned
* throughput settings. You must designate one attribute as the hash
* primary key for the table; you can optionally designate a second
* attribute as the range primary key. DynamoDB creates indexes on these
* key attributes for fast data access. Optionally, you can create one or
* more secondary indexes, which provide fast data access using non-key
* attributes.
*
*
* -
* DescribeTable - Returns metadata for a table, such as table
* size, status, and index information.
*
*
* -
* UpdateTable - Modifies the provisioned throughput settings for
* a table. Optionally, you can modify the provisioned throughput
* settings for global secondary indexes on the table.
*
*
* -
* ListTables - Returns a list of all tables associated with the
* current AWS account and endpoint.
*
*
* -
* DeleteTable - Deletes a table and all of its indexes.
*
*
*
*
*
*
*
* Reading Data
*
*
*
*
* -
* GetItem - Returns a set of attributes for the item that has a
* given primary key. By default, GetItem performs an eventually
* consistent read; however, applications can specify a strongly
* consistent read instead.
*
*
* -
* BatchGetItem - Performs multiple GetItem requests for
* data items using their primary keys, from one table or multiple
* tables. The response from BatchGetItem has a size limit of 1 MB
* and returns a maximum of 100 items. Both eventually consistent and
* strongly consistent reads can be used.
*
*
* -
* Query - Returns one or more items from a table or a secondary
* index. You must provide a specific hash key value. You can narrow the
* scope of the query using comparison operators against a range key
* value, or on the index key. Query supports either eventual or
* strong consistency. A single response has a size limit of 1 MB.
*
*
* -
* Scan - Reads every item in a table; the result set is
* eventually consistent. You can limit the number of items returned by
* filtering the data attributes, using conditional expressions.
* Scan can be used to enable ad-hoc querying of a table against
* non-key attributes; however, since this is a full table scan without
* using an index, Scan should not be used for any application
* query use case that requires predictable performance.
*
*
*
*
*
*
*
* Modifying Data
*
*
*
*
* -
* PutItem - Creates a new item, or replaces an existing item
* with a new item (including all the attributes). By default, if an item
* in the table already exists with the same primary key, the new item
* completely replaces the existing item. You can use conditional
* operators to replace an item only if its attribute values match
* certain conditions, or to insert a new item only if that item doesn't
* already exist.
*
*
* -
* UpdateItem - Modifies the attributes of an existing item. You
* can also use conditional operators to perform an update only if the
* item's attribute values match certain conditions.
*
*
* -
* DeleteItem - Deletes an item in a table by primary key. You
* can use conditional operators to perform a delete an item only if the
* item's attribute values match certain conditions.
*
*
* -
* BatchWriteItem - Performs multiple PutItem and
* DeleteItem requests across multiple tables in a single request.
* A failure of any request(s) in the batch will not cause the entire
* BatchWriteItem operation to fail. Supports batches of up to 25
* items to put or delete, with a maximum total request size of 1 MB.
