// BatchGetItem API operation for Amazon DynamoDB.
//
// 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 will return a partial result if the response
// size limit is exceeded, the table's provisioned throughput is exceeded, 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 will return 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 data set.
//
// If none of the items can be processed due to insufficient provisioned throughput
// on all of the tables in the request, then BatchGetItem will return 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 (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ErrorHandling.html#BatchOperations)
// 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 retrieves 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 Capacity Units Calculations (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/WorkingWithTables.html#CapacityUnitCalculations)

// can comprise as many as 25 put or delete requests. Individual items to be
// written can be as large as 400 KB.
//
// BatchWriteItem cannot update items. To update items, 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.
//
// Note that if none of the items can be processed due to insufficient provisioned
// throughput on all of the tables in the request, then BatchWriteItem will
// return a ProvisionedThroughputExceededException.
//
// If DynamoDB returns any unprocessed items, you should retry the batch operation

//
// With BatchWriteItem, you can efficiently write or delete large amounts of
// data, such as from Amazon Elastic MapReduce (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.
//
//    * There are more than 25 requests in the batch.
//
//    * Any individual item in a batch exceeds 400 KB.
//
//    * The total request size exceeds 16 MB.

// CreateTable is an asynchronous operation. Upon receiving a CreateTable request,

// You can optionally define secondary indexes on the new table, as part of

// DescribeLimits API operation for Amazon DynamoDB.
//
// Returns the current provisioned-capacity limits for your AWS account in a
// region, both for the region as a whole and for any one DynamoDB table that
// you create there.
//
// When you establish an AWS account, the account has initial limits 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
// limits that apply when you create a table there. For more information, see
// Limits (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Limits.html)
// page in the Amazon DynamoDB Developer Guide.
//
// Although you can increase these limits by filing a case at AWS Support Center
// (https://console.aws.amazon.com/support/home#/), obtaining the increase is
// not instantaneous. The DescribeLimits action lets you write code to compare
// the capacity you are currently using to those limits imposed by your account
// so that you have enough time to apply for an increase before you hit a limit.
//
// For example, you could use one of the AWS SDKs to do the following:
//
// Call DescribeLimits for a particular region to obtain your current account
// limits 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 limits for that region returned by DescribeLimits, along
// with the total current provisioned capacity levels you have calculated.
//
// This will let you see whether you are getting close to your account-level
// limits.
//
// The per-table limits apply only when you are creating a new table. They restrict
// the sum of the provisioned capacity of the new table itself and all its global
// secondary indexes.
//
// For existing tables and their GSIs, DynamoDB will not let you increase provisioned
// capacity extremely rapidly, but the only upper limit that applies is that
// the aggregate provisioned capacity over all your tables and GSIs cannot exceed
// either of the per-account limits.
//
// DescribeLimits should only be called periodically. You can expect throttling
// errors if you call it more than once in a minute.

// Query API operation for Amazon DynamoDB.
//
// The Query operation finds items based on primary key values. You can query
// any table or secondary index that has a composite primary key (a partition
// key and a sort key).
//
// Use the KeyConditionExpression parameter to provide a specific value for
// the partition key. The Query operation will return all of the items from
// the table or index with that partition key value. You can optionally narrow
// the scope of the Query operation by specifying a sort key value and a comparison
// operator in KeyConditionExpression. To further refine the Query results,
// you can optionally provide a FilterExpression. A FilterExpression determines
// which items within the results should be returned to you. All of the other
// results are discarded.
//
// A Query operation always returns a result set. If no matching items are found,
// the result set will be empty. Queries that do not return results consume
// the minimum number of read capacity units for that type of read operation.
//
// DynamoDB calculates the number of read capacity units consumed based on item
// size, not on the amount of data that is returned to an application. The number
// of capacity units consumed will be the same whether you request all of the
// attributes (the default behavior) or just some of them (using a projection
// expression). The number will also 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, the results are returned in numeric order; otherwise,
// the results are returned in order of UTF-8 bytes. By default, the sort order
// is ascending. To reverse the order, set the ScanIndexForward parameter to
// false.
//
// A single Query operation will read up to the maximum number of items set
// (if using the 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 Results (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Query.html#Query.Pagination)
// in the Amazon DynamoDB Developer Guide.
//
// FilterExpression is applied after a Query finishes, but before the results
// are returned. A FilterExpression cannot contain partition key or sort key
// attributes. You need to specify those attributes in the KeyConditionExpression.
//
// A Query operation can return an empty result set and a LastEvaluatedKey if
// all the items read for the page of results are filtered out.
//
// You can query a table, a local secondary index, or a global secondary index.
// For a query on a table or on a local secondary index, you can set the ConsistentRead
// parameter to true and obtain a strongly consistent result. Global secondary
// indexes support eventually consistent reads only, so do not specify ConsistentRead
// when querying a global secondary index.

// Scan API operation for Amazon DynamoDB.
//
// 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 number of scanned items exceeds the maximum data set size limit
// of 1 MB, the scan stops and results are returned to the user as a LastEvaluatedKey
// value to continue the scan in a subsequent operation. The results also include
// the number of items exceeding the limit. A scan can result in no table data
// meeting the filter criteria.
//
// A single Scan operation will read up to the maximum number of items set (if
// using the 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 Results (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Scan.html#Scan.Pagination)
// 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 (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Scan.html#Scan.ParallelScan)
// in the Amazon DynamoDB Developer Guide.
//
// Scan uses eventually consistent reads when accessing the data in a table;
// therefore, the result set might not include the changes to data in the table
// immediately before the operation began. If you need a consistent copy of
// the data, as of the time that the Scan begins, you can set the ConsistentRead
// parameter to true.

	// Specifies how to perform the update. Valid values are PUT (default), DELETE,
	// and ADD. The behavior depends on whether the specified primary key already
	// exists in the table.
	//
	// If an item with the specified Key is found in the table:
	//
	//    * PUT - Adds the specified attribute to the item. If the attribute already
	//    exists, it is replaced by the new value.
	//
	//    * DELETE - If no value is specified, the attribute and its value are removed
	//    from the item. The data type of the specified value must match the existing
	//    value's data type.
	//
	// If a set of values is specified, then those values are subtracted from the
	//    old set. For example, if the attribute value was the set [a,b,c] and the
	//    DELETE action specified [a,c], then the final attribute value would be
	//    [b]. Specifying an empty set is an error.
	//
	//    * ADD - If the attribute does not already exist, then the attribute and
	//    its values are added to the item. If the attribute does exist, then the
	//    behavior of ADD depends on the data type of the attribute:
	//
	// If the existing attribute is a number, and if Value is also a number, then
	//    the Value is mathematically added to the existing attribute. If Value
	//    is a negative number, then it is subtracted from the existing attribute.
	//
	//  If you use ADD to increment or decrement a number value for an item that
	//    doesn't exist before the update, DynamoDB uses 0 as the initial value.
	//
	// In addition, if you use ADD to update an existing item, and intend to increment
	//    or decrement an attribute value which does not yet exist, DynamoDB uses
	//    0 as the initial value. For example, suppose that the item you want to
	//    update does not yet have an attribute named itemcount, but you decide
	//    to ADD the number 3 to this attribute anyway, even though it currently
	//    does not exist. DynamoDB will create the itemcount attribute, set its
	//    initial value to 0, and finally add 3 to it. The result will be a new
	//    itemcount attribute in the item, with a value of 3.
	//
	// If the existing data type is a set, and if the Value is also a set, then
	//    the Value is added to the existing set. (This is a set operation, not
	//    mathematical addition.) For example, if the attribute value was the set
	//    [1,2], and the ADD action specified [3], then the final attribute value
	//    would be [1,2,3]. An error occurs if an Add action is specified for a
	//    set attribute and the attribute type specified does not match the existing
	//    set type.
	//
	// Both sets must have the same primitive data type. For example, if the existing
	//    data type is a set of strings, the Value must also be a set of strings.
	//    The same holds true for number sets and binary sets.
	//
	// This action is only valid for an existing attribute whose data type is number
	//    or is a set. Do not use ADD for any other data types.
	//
	// If no item with the specified Key is found:
	//
	//    * PUT - DynamoDB creates a new item with the specified primary key, and
	//    then adds the attribute.
	//
	//    * DELETE - Nothing happens; there is no attribute to delete.
	//
	//    * ADD - DynamoDB creates an item with the supplied primary key and number
	//    (or set of numbers) for the attribute value. The only data types allowed
	//    are number and number set; no other data types can be specified.

	// The condition that specifies the key value(s) for items to be retrieved by

	//
	// The condition must perform an equality test on a single partition key value.
	//
	// The condition can optionally perform one of several comparison tests on a
	// single sort key value. This allows Query to retrieve one item with a given
	// partition key value and sort key value, or several items that have the same
	// partition key value but different sort key values.
	//
	// The partition key equality test is required, and must be specified in the
	// following format:
	//
	// partitionKeyName=:partitionkeyval
	//
	// If you also want to provide a condition for the sort key, it must be combined
	// using AND with the condition for the sort key. Following is an example, using

	//
	// partitionKeyName=:partitionkeyvalANDsortKeyName=:sortkeyval
	//

	//
	//    * sortKeyName<:sortkeyval - true if the sort key value is less than :sortkeyval.

	//    * sortKeyName<=:sortkeyval - true if the sort key value is less than or
	//    equal to :sortkeyval.
	//
	//    * sortKeyName>:sortkeyval - true if the sort key value is greater than
	//    :sortkeyval.
	//
	//    * sortKeyName>= :sortkeyval - true if the sort key value is greater than
	//    or equal to :sortkeyval.
	//
	//    * sortKeyNameBETWEEN:sortkeyval1AND:sortkeyval2 - true if the sort key
	//    value is greater than or equal to :sortkeyval1, and less than or equal
	//    to :sortkeyval2.
	//
	//    * begins_with (sortKeyName, :sortkeyval) - true if the sort key value
	//    begins with a particular operand. (You cannot use this function with a
	//    sort key that is of type Number.) Note that the function name begins_with
	//    is case-sensitive.
	//
	// Use the ExpressionAttributeValues parameter to replace tokens such as :partitionval
	// and :sortval with actual values at runtime.
	//
	// You can optionally use the ExpressionAttributeNames parameter to replace
	// the names of the partition key and sort key with placeholder tokens. This
	// option might be necessary if an attribute name conflicts with a DynamoDB
	// reserved word. For example, the following KeyConditionExpression parameter

	//    * ALL_ATTRIBUTES - Returns all of the item attributes from the specified

	//    attribute already exist, they are replaced by the new values. You can
	//    also use SET to add or subtract from an attribute that is of type Number.
	//    For example: SET myNum = myNum + :val
	//
	// SET supports the following functions:
	//
	// if_not_exists (path, operand) - if the item does not contain an attribute
	//    at the specified path, then if_not_exists evaluates to operand; otherwise,
	//    it evaluates to path. You can use this function to avoid overwriting an
	//    attribute that may already be present in the item.
	//
	// list_append (operand, operand) - evaluates to a list with a new element added
	//    to it. You can append the new element to the start or the end of the list
	//    by reversing the order of the operands.
	//
	// These function names are case-sensitive.
	//
	//    * REMOVE - Removes one or more attributes from an item.
	//
	//    * ADD - Adds the specified value to the item, if the attribute does not
	//    already exist. If the attribute does exist, then the behavior of ADD depends
	//    on the data type of the attribute:
	//
	// If the existing attribute is a number, and if Value is also a number, then
	//    Value is mathematically added to the existing attribute. If Value is a
	//    negative number, then it is subtracted from the existing attribute.
	//
	// If you use ADD to increment or decrement a number value for an item that
	//    doesn't exist before the update, DynamoDB uses 0 as the initial value.
	//
	// Similarly, if you use ADD for an existing item to increment or decrement
	//    an attribute value that doesn't exist before the update, DynamoDB uses
	//    0 as the initial value. For example, suppose that the item you want to
	//    update doesn't have an attribute named itemcount, but you decide to ADD
	//    the number 3 to this attribute anyway. DynamoDB will create the itemcount
	//    attribute, set its initial value to 0, and finally add 3 to it. The result
	//    will be a new itemcount attribute in the item, with a value of 3.
	//
	// If the existing data type is a set and if Value is also a set, then Value
	//    is added to the existing set. For example, if the attribute value is the
	//    set [1,2], and the ADD action specified [3], then the final attribute
	//    value is [1,2,3]. An error occurs if an ADD action is specified for a
	//    set attribute and the attribute type specified does not match the existing
	//    set type.
	//
	// Both sets must have the same primitive data type. For example, if the existing
	//    data type is a set of strings, the Value must also be a set of strings.
	//
	// The ADD action only supports Number and set data types. In addition, ADD
	//    can only be used on top-level attributes, not nested attributes.
	//
	//    * DELETE - Deletes an element from a set.
	//
	// If a set of values is specified, then those values are subtracted from the
	//    old set. For example, if the attribute value was the set [a,b,c] and the
	//    DELETE action specifies [a,c], then the final attribute value is [b].
	//    Specifying an empty set is an error.
	//
	// The DELETE action only supports set data types. In addition, DELETE can only
	//    be used on top-level attributes, not nested attributes.
	//
	// You can have many actions in a single expression, such as the following:
	// SET a=:value1, b=:value2 DELETE :value3, :value4, :value5
