The GetItem operation returns a set of attributes for the item with the given
primary key. If there is no matching item, GetItem does not return any data
and there will be no Item element in the response.
GetItem provides an eventually consistent read by default. If your application
requires a strongly consistent read, set ConsistentRead to true. Although
a strongly consistent read might take more time than an eventually consistent read,
it always returns the last updated value.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginGetItem and EndGetItem.

| Exception | Condition |
|---|---|
| InternalServerErrorException | An error occurred on the server side. |
| ProvisionedThroughputExceededException | Your request rate is too high. The Amazon Web Services SDKs for DynamoDB automatically retry requests that receive this exception. Your request is eventually successful, unless your retry queue is too large to finish. Reduce the frequency of requests and use exponential backoff. For more information, go to Error Retries and Exponential Backoff in the Amazon DynamoDB Developer Guide. |
| RequestLimitExceededException | Throughput exceeds the current throughput quota for your account. Please contact Amazon Web Services Support to request a quota increase. |
