/**
* Interface for accessing DynamoDB.
*
* Note: Do not directly implement this interface, new methods are added to it regularly. Extend from

*
*
* Amazon DynamoDB
*
* Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with
* seamless scalability. DynamoDB lets you offload the administrative burdens of operating and scaling a distributed
* database, so that you don't have to worry about hardware provisioning, setup and configuration, replication, software
* patching, or cluster scaling.
*
*
* With DynamoDB, you can create database tables that can store and retrieve any amount of data, and serve any level of
* request traffic. You can scale up or scale down your tables' throughput capacity without downtime or performance
* degradation, and use the Amazon Web Services Management Console to monitor resource utilization and performance
* metrics.
*
*
* DynamoDB automatically spreads the data and traffic for your tables over a sufficient number of servers to handle
* your throughput and storage requirements, while maintaining consistent and fast performance. All of your data is
* stored on solid state disks (SSDs) and automatically replicated across multiple Availability Zones in an Amazon Web
* Services Region, providing built-in high availability and data durability.

* The BatchGetItem operation returns the attributes of one or more items from one or more tables. You
* identify requested items by primary key.
*
*
* A single operation can retrieve up to 16 MB of data, which can contain as many as 100 items.
* BatchGetItem returns a partial result if the response size limit is exceeded, the table's
* provisioned throughput is exceeded, more than 1MB per partition is requested, or an internal processing failure
* occurs. If a partial result is returned, the operation returns a value for UnprocessedKeys. You can
* use this value to retry the operation starting with the next item to get.
*
*
*
* If you request more than 100 items, BatchGetItem returns a ValidationException with the
* message "Too many items requested for the BatchGetItem call."
*
*
*
* For example, if you ask to retrieve 100 items, but each individual item is 300 KB in size, the system returns 52
* items (so as not to exceed the 16 MB limit). It also returns an appropriate UnprocessedKeys value so
* you can get the next page of results. If desired, your application can include its own logic to assemble the
* pages of results into one dataset.
*
*
* If none of the items can be processed due to insufficient provisioned throughput on all of the tables in
* the request, then BatchGetItem returns a ProvisionedThroughputExceededException. If
* at least one of the items is successfully processed, then BatchGetItem completes
* successfully, while returning the keys of the unread items in UnprocessedKeys.
*
*
*
* If DynamoDB returns any unprocessed items, you should retry the batch operation on those items. However, we
* strongly recommend that you use an exponential backoff algorithm. If you retry the batch operation
* immediately, the underlying read or write requests can still fail due to throttling on the individual tables. If
* you delay the batch operation using exponential backoff, the individual requests in the batch are much more
* likely to succeed.
*
*
* For more information, see Batch
* Operations and Error Handling in the Amazon DynamoDB Developer Guide.
*
*
*
* By default, BatchGetItem performs eventually consistent reads on every table in the request. If you
* want strongly consistent reads instead, you can set ConsistentRead to true for any or
* all tables.
*
*
* In order to minimize response latency, BatchGetItem may retrieve items in parallel.
*
*
* When designing your application, keep in mind that DynamoDB does not return items in any particular order. To
* help parse the response by item, include the primary key values for the items in your request in the
* ProjectionExpression parameter.
*
*
* If a requested item does not exist, it is not returned in the result. Requests for nonexistent items consume the
* minimum read capacity units according to the type of read. For more information, see Working with Tables in the Amazon DynamoDB Developer Guide.

*
* The BatchWriteItem operation puts or deletes multiple items in one or more tables. A single call to
* BatchWriteItem can transmit up to 16MB of data over the network, consisting of up to 25 item put or
* delete operations. While individual items can be up to 400 KB once stored, it's important to note that an item's
* representation might be greater than 400KB while being sent in DynamoDB's JSON format for the API call. For more
* details on this distinction, see Naming Rules and Data Types.
*
*
*
* BatchWriteItem cannot update items. If you perform a BatchWriteItem operation on an
* existing item, that item's values will be overwritten by the operation and it will appear like it was updated. To
* update items, we recommend you use the UpdateItem action.
*
*
*
* The individual PutItem and DeleteItem operations specified in
* BatchWriteItem are atomic; however BatchWriteItem as a whole is not. If any requested
* operations fail because the table's provisioned throughput is exceeded or an internal processing failure occurs,
* the failed operations are returned in the UnprocessedItems response parameter. You can investigate
* and optionally resend the requests. Typically, you would call BatchWriteItem in a loop. Each
* iteration would check for unprocessed items and submit a new BatchWriteItem request with those
* unprocessed items until all items have been processed.
*
*
* If none of the items can be processed due to insufficient provisioned throughput on all of the tables in
* the request, then BatchWriteItem returns a ProvisionedThroughputExceededException.
*
*
*
* If DynamoDB returns any unprocessed items, you should retry the batch operation on those items. However, we
* strongly recommend that you use an exponential backoff algorithm. If you retry the batch operation

* For more information, see Batch Operations and Error Handling in the Amazon DynamoDB Developer Guide.
*
*
*
* With BatchWriteItem, you can efficiently write or delete large amounts of data, such as from Amazon
* EMR, or copy data from another database into DynamoDB. In order to improve performance with these large-scale
* operations, BatchWriteItem does not behave in the same way as individual PutItem and
* DeleteItem calls would. For example, you cannot specify conditions on individual put and delete
* requests, and BatchWriteItem does not return deleted items in the response.
*
*
* If you use a programming language that supports concurrency, you can use threads to write items in parallel. Your
* application must include the necessary logic to manage the threads. With languages that don't support threading,
* you must update or delete the specified items one at a time. In both situations, BatchWriteItem
* performs the specified put and delete operations in parallel, giving you the power of the thread pool approach
* without having to introduce complexity into your application.
*
*
* Parallel processing reduces latency, but each specified put and delete request consumes the same number of write
* capacity units whether it is processed in parallel or not. Delete operations on nonexistent items consume one
* write capacity unit.
*
*
* If one or more of the following is true, DynamoDB rejects the entire batch write operation:
*
*
* -
*
* One or more tables specified in the BatchWriteItem request does not exist.
*
*
* -
*
* Primary key attributes specified on an item in the request do not match those in the corresponding table's
* primary key schema.
*
*
* -
*
* You try to perform multiple operations on the same item in the same BatchWriteItem request. For
* example, you cannot put and delete the same item in the same BatchWriteItem request.

* operations).

* Deletes the resource-based policy attached to the resource, which can be a table or stream.
*
*
* DeleteResourcePolicy is an idempotent operation; running it multiple times on the same resource
* doesn't result in an error response, unless you specify an ExpectedRevisionId, which will
* then return a PolicyNotFoundException.
*
*
*
* To make sure that you don't inadvertently lock yourself out of your own resources, the root principal in your
* Amazon Web Services account can perform DeleteResourcePolicy requests, even if your resource-based
* policy explicitly denies the root principal's access.
*
*
*
* DeleteResourcePolicy is an asynchronous operation. If you issue a GetResourcePolicy
* request immediately after running the DeleteResourcePolicy request, DynamoDB might still return the
* deleted policy. This is because the policy for your resource might not have been deleted yet. Wait for a few
* seconds, and then try the GetResourcePolicy request again.

* @throws PolicyNotFoundException
* The operation tried to access a nonexistent resource-based policy.
*
* If you specified an ExpectedRevisionId, it's possible that a policy is present for the
* resource but its revision ID didn't match the expected value.
* @throws ResourceInUseException
* The operation conflicts with the resource's availability. For example, you attempted to recreate an
* existing table, or tried to delete a table currently in the CREATING state.
* @throws LimitExceededException
* There is no limit to the number of daily on-demand backups that can be taken.
*
*
* For most purposes, up to 500 simultaneous table operations are allowed per account. These operations
* include CreateTable, UpdateTable, DeleteTable,
* UpdateTimeToLive, RestoreTableFromBackup, and
* RestoreTableToPointInTime.
*
*
* When you are creating a table with one or more secondary indexes, you can have up to 250 such requests
* running at a time. However, if the table or index specifications are complex, then DynamoDB might
* temporarily reduce the number of concurrent operations.
*
*
* When importing into DynamoDB, up to 50 simultaneous import table operations are allowed per account.

* Returns the current provisioned-capacity quotas for your Amazon Web Services account in a Region, both for the

*
*
* When you establish an Amazon Web Services account, the account has initial quotas on the maximum read capacity
* units and write capacity units that you can provision across all of your DynamoDB tables in a given Region. Also,
* there are per-table quotas that apply when you create a table there. For more information, see Service, Account, and Table
* Quotas page in the Amazon DynamoDB Developer Guide.
*
*
* Although you can increase these quotas by filing a case at Amazon Web Services Support Center, obtaining the
* increase is not instantaneous. The DescribeLimits action lets you write code to compare the capacity
* you are currently using to those quotas imposed by your account so that you have enough time to apply for an
* increase before you hit a quota.
*
*
* For example, you could use one of the Amazon Web Services SDKs to do the following:
*
*
* -
*
* Call DescribeLimits for a particular Region to obtain your current account quotas on provisioned
* capacity there.
*
*
* -
*
* Create a variable to hold the aggregate read capacity units provisioned for all your tables in that Region, and
* one to hold the aggregate write capacity units. Zero them both.
*

* -

* Call ListTables to obtain a list of all your DynamoDB tables.

* -
*
* For each table name listed by ListTables, do the following:
*
*
* -
*
* Call DescribeTable with the table name.
*
*
* -
*
* Use the data returned by DescribeTable to add the read capacity units and write capacity units
* provisioned for the table itself to your variables.
*
*
* -
*
* If the table has one or more global secondary indexes (GSIs), loop over these GSIs and add their provisioned
* capacity values to your variables as well.
*
*
*
*
* -
*
* Report the account quotas for that Region returned by DescribeLimits, along with the total current
* provisioned capacity levels you have calculated.
*
*
*

* @throws TransactionInProgressException
* The transaction with the given request token is already in progress.
*
* Recommended Settings
*
*
*
* This is a general recommendation for handling the TransactionInProgressException. These
* settings help ensure that the client retries will trigger completion of the ongoing
* TransactWriteItems request.
*
*
*
* -
*
* Set clientExecutionTimeout to a value that allows at least one retry to be processed after 5
* seconds have elapsed since the first attempt for the TransactWriteItems operation.
*
*
* -
*
* Set socketTimeout to a value a little lower than the requestTimeout setting.
*
*
* -
*
* requestTimeout should be set based on the time taken for the individual retries of a single
* HTTP request for your use case, but setting it to 1 second or higher should work well to reduce chances
* of retries and TransactionInProgressException errors.
*
*
* -
*
* Use exponential backoff when retrying and tune backoff if needed.
*
*
*
*
* Assuming default retry policy, example timeout settings based on the guidelines above are as follows:
*
*
* Example timeline:
*
*
* -
*
* 0-1000 first attempt
*
*
* -
*
* 1000-1500 first sleep/delay (default retry policy uses 500 ms as base delay for 4xx errors)
*
*
* -
*
* 1500-2500 second attempt
*
*
* -
*
* 2500-3500 second sleep/delay (500 * 2, exponential backoff)
*
*
* -
*
* 3500-4500 third attempt
*
*
* -
*
* 4500-6500 third sleep/delay (500 * 2^2)
*
*
* -
*
* 6500-7500 fourth attempt (this can trigger inline recovery since 5 seconds have elapsed since the first
* attempt reached TC)

* be the same whether or not you use a FilterExpression.
*
*
*
* Query results are always sorted by the sort key value. If the data type of the sort key is Number,

* default, the sort order is ascending. To reverse the order, set the ScanIndexForward parameter to
* false.
*

* Limit parameter) or a maximum of 1 MB of data and then apply any filtering to the results using
* FilterExpression. If LastEvaluatedKey is present in the response, you will need to
* paginate the result set. For more information, see Paginating

*
* The Scan operation returns one or more items and item attributes by accessing every item in a table
* or a secondary index. To have DynamoDB return fewer items, you can provide a FilterExpression
* operation.
*
*
* If the total size of scanned items exceeds the maximum dataset size limit of 1 MB, the scan completes and results
* are returned to the user. The LastEvaluatedKey value is also returned and the requestor can use the
* LastEvaluatedKey to continue the scan in a subsequent operation. Each scan response also includes
* number of items that were scanned (ScannedCount) as part of the request. If using a FilterExpression
* , a scan result can result in no items meeting the criteria and the Count will result in zero. If
* you did not use a FilterExpression in the scan request, then Count is the same as
* ScannedCount.
*
*
*
* Count and ScannedCount only return the count of items specific to a single scan request
* and, unless the table is less than 1MB, do not represent the total number of items in the table.
*
*
*
* A single Scan operation first reads up to the maximum number of items set (if using the
* Limit parameter) or a maximum of 1 MB of data and then applies any filtering to the results if a
* FilterExpression is provided. If LastEvaluatedKey is present in the response,
* pagination is required to complete the full table scan. For more information, see Paginating the
* Results in the Amazon DynamoDB Developer Guide.
*
*
* Scan operations proceed sequentially; however, for faster performance on a large table or secondary
* index, applications can request a parallel Scan operation by providing the Segment and
* TotalSegments parameters. For more information, see Parallel
* Scan in the Amazon DynamoDB Developer Guide.
*
*
* By default, a Scan uses eventually consistent reads when accessing the items in a table. Therefore,
* the results from an eventually consistent Scan may not include the latest item changes at the time
* the scan iterates through each item in the table. If you require a strongly consistent read of each item as the
* scan iterates through the items in the table, you can set the ConsistentRead parameter to true.
* Strong consistency only relates to the consistency of the read at the item level.
*
*
*
* DynamoDB does not provide snapshot isolation for a scan operation when the ConsistentRead parameter
* is set to true. Thus, a DynamoDB scan operation does not guarantee that all reads in a scan see a consistent
* snapshot of the table when the scan operation was requested.
*
*
*
* @param scanRequest
* Represents the input of a Scan operation.
* @return Result of the Scan operation returned by the service.

* 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.
* @throws ResourceNotFoundException

*
* @throws TransactionInProgressException
* The transaction with the given request token is already in progress.
*
* Recommended Settings
*
*
*
* This is a general recommendation for handling the TransactionInProgressException. These
* settings help ensure that the client retries will trigger completion of the ongoing
* TransactWriteItems request.
*
*
*
* -
*
* Set clientExecutionTimeout to a value that allows at least one retry to be processed after 5
* seconds have elapsed since the first attempt for the TransactWriteItems operation.
*
*
* -
*
* Set socketTimeout to a value a little lower than the requestTimeout setting.
*
*
* -
*
* requestTimeout should be set based on the time taken for the individual retries of a single
* HTTP request for your use case, but setting it to 1 second or higher should work well to reduce chances
* of retries and TransactionInProgressException errors.
*
*
* -
*
* Use exponential backoff when retrying and tune backoff if needed.
*
*
*
*
* Assuming default retry policy, example timeout settings based on the guidelines above are as follows:
*
*
* Example timeline:
*
*
* -
*
* 0-1000 first attempt
*
*
* -
*
* 1000-1500 first sleep/delay (default retry policy uses 500 ms as base delay for 4xx errors)
*
*
* -
*
* 1500-2500 second attempt
*
*
* -
*
* 2500-3500 second sleep/delay (500 * 2, exponential backoff)
*
*
* -
*
* 3500-4500 third attempt
*
*
* -
*
* 4500-6500 third sleep/delay (500 * 2^2)
*
*
* -
*
* 6500-7500 fourth attempt (this can trigger inline recovery since 5 seconds have elapsed since the first
* attempt reached TC)
*
