  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.

  This operation allows you to perform batch reads or writes on data stored in

  Each read statement in a `BatchExecuteStatement` must specify
  an equality condition on all key attributes. This enforces that each `SELECT`
  statement in a batch returns at most a single item. For more information, see
  [Running batch operations with PartiQL for DynamoDB
  ](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ql-reference.multiplestatements.batching.html).

  The entire batch must consist of either read statements or write statements, you
  cannot mix both in one batch.

  A HTTP 200 response does not mean that all statements in the
  BatchExecuteStatement
  succeeded. Error details for individual statements can be found under the
  [Error](https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_BatchStatementResponse.html#DDB-Type-BatchStatementResponse-Error)

  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](https://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` 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](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/WorkingWithTables.html#CapacityUnitCalculations)
  in the *Amazon DynamoDB Developer
  Guide*.

  `BatchGetItem` will result in a `ValidationException` if the
  same key is specified multiple times.

  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](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/HowItWorks.NamingRulesDataTypes.html).

  `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.

  For tables and indexes with provisioned capacity, 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`. For all tables and indexes, if
  none of the items can be processed due to other throttling scenarios (such as
  exceeding
  partition level limits), then `BatchWriteItem` returns a
  `ThrottlingException`.

  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](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/ErrorHandling.html#Programming.Errors.BatchOperations)
  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.

    *
  Your request contains at least two items with identical hash and range keys
  (which essentially is two put operations).

    *
  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.

    *
  Any individual items with keys exceeding the key length limits. For a
  partition key, the limit is 2048 bytes and for a sort key, the limit is 1024
  bytes.

  Creates a backup for an existing table.

  Each time you create an on-demand backup, the entire table data is backed up.
  There
  is no limit to the number of on-demand backups that can be taken.

  When you create an on-demand backup, a time marker of the request is cataloged,
  and
  the backup is created asynchronously, by applying all changes until the time of
  the
  request to the last full table snapshot. Backup requests are processed
  instantaneously
  and become available for restore within minutes.

  You can call `CreateBackup` at a maximum rate of 50 times per
  second.

  All backups in DynamoDB work without consuming any provisioned throughput on the
  table.

  If you submit a backup request on 2018-12-14 at 14:25:00, the backup is
  guaranteed to
  contain all data committed to the table up to 14:24:00, and data committed after
  14:26:00 will not be. The backup might contain data modifications made between
  14:24:00
  and 14:26:00. On-demand backup does not support causal consistency.

  Creates a global table from an existing table.

  A global table creates a replication
  relationship between two or more DynamoDB tables with the same table name in the
  provided Regions.

  This documentation is for version 2017.11.29 (Legacy) of global tables, which
  should be avoided for new global tables. Customers should use [Global Tables version 2019.11.21
  (Current)](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/GlobalTables.html)
  when possible, because it provides greater flexibility, higher efficiency, and
  consumes less write capacity than 2017.11.29 (Legacy).

  To determine which version you're using, see [Determining the global table version you are
  using](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/globaltables.DetermineVersion.html).
  To update existing global tables from version 2017.11.29 (Legacy) to version
  2019.11.21 (Current), see [Upgrading global tables](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/V2globaltables_upgrade.html).

  If you want to add a new replica table to a global table, each of the following
  conditions must be true:

    *
  The table must have the same primary key as all of the other replicas.

    *
  The table must have the same name as all of the other replicas.

    *
  The table must have DynamoDB Streams enabled, with the stream containing both
  the new and the old images of the item.

    *
  None of the replica tables in the global table can contain any data.

  If global secondary indexes are specified, then the following conditions must
  also be
  met:

    *
  The global secondary indexes must have the same name.

    *
  The global secondary indexes must have the same hash key and sort key (if
  present).

  If local secondary indexes are specified, then the following conditions must
  also be
  met:

    *
  The local secondary indexes must have the same name.

    *
  The local secondary indexes must have the same hash key and sort key (if
  present).

  Write capacity settings should be set consistently across your replica tables
  and
  secondary indexes. DynamoDB strongly recommends enabling auto scaling to manage
  the
  write capacity settings for all of your global tables replicas and indexes.

  If you prefer to manage write capacity settings manually, you should provision
  equal replicated write capacity units to your replica tables. You should also
  provision equal replicated write capacity units to matching secondary indexes
  across
  your global table.

  Returns the current provisioned-capacity quotas for your Amazon Web Services
  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 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](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Limits.html)
  page in the *Amazon DynamoDB
  Developer Guide*.

  Although you can increase these quotas by filing a case at [Amazon Web Services 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 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:

    1.
  Call `DescribeLimits` for a particular Region to obtain your
  current account quotas on provisioned capacity there.

    2.
  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.

    3.
  Call `ListTables` to obtain a list of all your DynamoDB
  tables.

    4.
  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.

    5.
  Report the account quotas 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
  quotas.

  The per-table quotas 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 doesn't let you increase
  provisioned
  capacity extremely rapidly, but the only quota that applies is that the
  aggregate
  provisioned capacity over all your tables and GSIs cannot exceed either of the
  per-account quotas.

  `DescribeLimits` should only be called periodically. You can expect
  throttling errors if you call it more than once in a minute.

  You must provide the name of the partition key attribute and a single value for
  that
  attribute.

  `Query` returns all items with that partition key value.
  Optionally, you can provide a sort key attribute and use a comparison operator
  to refine
  the search results.

  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](https://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

  The `Scan` operation returns one or more items and item attributes by

  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](https://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](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Scan.html#Scan.ParallelScan)
  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.

  The `UpdateTimeToLive` method enables or disables Time to Live (TTL) for
  the specified table.

  A successful `UpdateTimeToLive` call returns the current
  `TimeToLiveSpecification`. It can take up to one hour for the change to
  fully process. Any additional `UpdateTimeToLive` calls for the same table
  during this one hour duration result in a `ValidationException`.

  TTL compares the current time in epoch time format to the time stored in the TTL
  attribute of an item. If the epoch time value stored in the attribute is less
  than the
  current time, the item is marked as expired and subsequently deleted.

  The epoch time format is the number of seconds elapsed since 12:00:00 AM January
  1, 1970 UTC.

  DynamoDB deletes expired items on a best-effort basis to ensure availability of
  throughput for other data operations.

  DynamoDB typically deletes expired items within two days of expiration. The
  exact
  duration within which an item gets deleted after expiration is specific to the
  nature of the workload. Items that have expired and not been deleted will still
  show
  up in reads, queries, and scans.

  As items are deleted, they are removed from any local secondary index and global
  secondary index immediately in the same eventually consistent way as a standard
  delete
  operation.
