restore-table-to-point-in-time

Description

Restores the specified table to the specified point in time within EarliestRestorableDateTime and LatestRestorableDateTime . You can restore your table to any point in time during the last 35 days. Any number of users can execute up to 50 concurrent restores (any type of restore) in a given account.

When you restore using point in time recovery, DynamoDB restores your table data to the state based on the selected date and time (day:hour:minute:second) to a new table.

Along with data, the following are also included on the new restored table using point in time recovery:

  • Global secondary indexes (GSIs)
  • Local secondary indexes (LSIs)
  • Provisioned read and write capacity
  • Encryption settings

Warning

All these settings come from the current settings of the source table at the time of restore.

You must manually set up the following on the restored table:

  • Auto scaling policies
  • IAM policies
  • Amazon CloudWatch metrics and alarms
  • Tags
  • Stream settings
  • Time to Live (TTL) settings
  • Point in time recovery settings

--global-secondary-index-override (list)

List of global secondary indexes for the restored table. The indexes provided should match existing secondary indexes. You can choose to exclude some or all of the indexes at the time of restore.

(structure)

Represents the properties of a global secondary index.

IndexName -> (string)

The name of the global secondary index. The name must be unique among all other indexes on this table.

KeySchema -> (list)

The complete key schema for a global secondary index, which consists of one or more pairs of attribute names and key types:

  • HASH - partition key
  • RANGE - sort key

Note

The partition key of an item is also known as its hash attribute . The term “hash attribute” derives from DynamoDB’s usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

The sort key of an item is also known as its range attribute . The term “range attribute” derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

(structure)

Represents a single element of a key schema. A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index.

A KeySchemaElement represents exactly one attribute of the primary key. For example, a simple primary key would be represented by one KeySchemaElement (for the partition key). A composite primary key would require one KeySchemaElement for the partition key, and another KeySchemaElement for the sort key.

A KeySchemaElement must be a scalar, top-level attribute (not a nested attribute). The data type must be one of String, Number, or Binary. The attribute cannot be nested within a List or a Map.

AttributeName -> (string)

The name of a key attribute.

KeyType -> (string)

The role that this key attribute will assume:

  • HASH - partition key
  • RANGE - sort key

Note

The partition key of an item is also known as its hash attribute . The term “hash attribute” derives from DynamoDB’s usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

The sort key of an item is also known as its range attribute . The term “range attribute” derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

Projection -> (structure)

Represents attributes that are copied (projected) from the table into the global secondary index. These are in addition to the primary key attributes and index key attributes, which are automatically projected.

ProjectionType -> (string)

The set of attributes that are projected into the index:

  • KEYS_ONLY - Only the index and primary keys are projected into the index.
  • INCLUDE - In addition to the attributes described in KEYS_ONLY , the secondary index will include other non-key attributes that you specify.
  • ALL - All of the table attributes are projected into the index.

When using the DynamoDB console, ALL is selected by default.

NonKeyAttributes -> (list)

Represents the non-key attribute names which will be projected into the index.

For local secondary indexes, the total count of NonKeyAttributes summed across all of the local secondary indexes, must not exceed 100. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

(string)

ProvisionedThroughput -> (structure)

MaxWriteRequestUnits -> (long)

Maximum number of write request units for the specified table.

To specify a maximum OnDemandThroughput on your table, set the value of MaxWriteRequestUnits as greater than or equal to 1. To remove the maximum OnDemandThroughput that is currently set on your table, set the value of MaxWriteRequestUnits to -1.

WarmThroughput -> (structure)

Represents the warm throughput value (in read units per second and write units per second) for the specified secondary index. If you use this parameter, you must specify ReadUnitsPerSecond , WriteUnitsPerSecond , or both.

ReadUnitsPerSecond -> (long)

Represents the number of read operations your base table can instantaneously support.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

TableDescription -> (structure)

Represents the properties of a table.

AttributeDefinitions -> (list)

An array of AttributeDefinition objects. Each of these objects describes one attribute in the table and index key schema.

Each AttributeDefinition object in this array is composed of:

  • AttributeName - The name of the attribute.
  • AttributeType - The data type for the attribute.

(structure)

Represents an attribute for describing the schema for the table and indexes.

AttributeName -> (string)

A name for the attribute.

AttributeType -> (string)

The data type for the attribute, where:

  • S - the attribute is of type String
  • N - the attribute is of type Number
  • B - the attribute is of type Binary

TableName -> (string)

The name of the table.

The primary key structure for the table. Each KeySchemaElement consists of:

  • AttributeName - The name of the attribute.
  • KeyType - The role of the attribute:
    • HASH - partition key
    • RANGE - sort key

Note

The partition key of an item is also known as its hash attribute . The term “hash attribute” derives from DynamoDB’s usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

The sort key of an item is also known as its range attribute . The term “range attribute” derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

For more information about primary keys, see Primary Key in the Amazon DynamoDB Developer Guide .

(structure)

Represents a single element of a key schema. A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index.

A KeySchemaElement represents exactly one attribute of the primary key. For example, a simple primary key would be represented by one KeySchemaElement (for the partition key). A composite primary key would require one KeySchemaElement for the partition key, and another KeySchemaElement for the sort key.

A KeySchemaElement must be a scalar, top-level attribute (not a nested attribute). The data type must be one of String, Number, or Binary. The attribute cannot be nested within a List or a Map.

AttributeName -> (string)

The name of a key attribute.

KeyType -> (string)

The role that this key attribute will assume:

  • HASH - partition key
  • RANGE - sort key

The sort key of an item is also known as its range attribute . The term “range attribute” derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

TableStatus -> (string)

The current state of the table:

  • CREATING - The table is being created.
  • UPDATING - The table/index configuration is being updated. The table/index remains available for data operations when UPDATING .
  • DELETING - The table is being deleted.
  • ACTIVE - The table is ready for use.
  • INACCESSIBLE_ENCRYPTION_CREDENTIALS - The KMS key used to encrypt the table in inaccessible. Table operations may fail due to failure to use the KMS key. DynamoDB will initiate the table archival process when a table’s KMS key remains inaccessible for more than seven days.
  • ARCHIVING - The table is being archived. Operations are not allowed until archival is complete.
  • ARCHIVED - The table has been archived. See the ArchivalReason for more information.

CreationDateTime -> (timestamp)

The date and time when the table was created, in UNIX epoch time format.

ProvisionedThroughput -> (structure)

The provisioned throughput settings for the table, consisting of read and write capacity units, along with data about increases and decreases.

LastIncreaseDateTime -> (timestamp)

The date and time of the last provisioned throughput increase for this table.

LastDecreaseDateTime -> (timestamp)

The date and time of the last provisioned throughput decrease for this table.

Eventually consistent reads require less effort than strongly consistent reads, so a setting of 50 ReadCapacityUnits per second provides 100 eventually consistent ReadCapacityUnits per second.

WriteCapacityUnits -> (long)

The maximum number of writes consumed per second before DynamoDB returns a ThrottlingException .

TableSizeBytes -> (long)

The total size of the specified table, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

The Amazon Resource Name (ARN) that uniquely identifies the table.

TableId -> (string)

Unique identifier for the table for which the backup was created.

BillingModeSummary -> (structure)

Contains the details for the read/write capacity mode.

BillingMode -> (string)

Controls how you are charged for read and write throughput and how you manage capacity. This setting can be changed later.

  • PROVISIONED - Sets the read/write capacity mode to PROVISIONED . We recommend using PROVISIONED for predictable workloads.
  • PAY_PER_REQUEST - Sets the read/write capacity mode to PAY_PER_REQUEST . We recommend using PAY_PER_REQUEST for unpredictable workloads.

LastUpdateToPayPerRequestDateTime -> (timestamp)

Represents the time when PAY_PER_REQUEST was last set as the read/write capacity mode.

LocalSecondaryIndexes -> (list)

Represents one or more local secondary indexes on the table. Each index is scoped to a given partition key value.

Each element is composed of:

  • IndexName - The name of the local secondary index.
  • KeySchema - Specifies the complete index key schema. The attribute names in the key schema must be between 1 and 255 characters (inclusive). The key schema must begin with the same partition key as the table.
  • Projection - Specifies attributes that are copied (projected) from the table into the index. These are in addition to the primary key attributes and index key attributes, which are automatically projected. Each attribute specification is composed of:
    • ProjectionType - One of the following:
      • KEYS_ONLY - Only the index and primary keys are projected into the index.
      • INCLUDE - Only the specified table attributes are projected into the index. The list of projected attributes is in NonKeyAttributes .
      • ALL - All of the table attributes are projected into the index.
    • NonKeyAttributes - A list of one or more non-key attribute names that are projected into the secondary index. The total count of attributes provided in NonKeyAttributes , summed across all of the secondary indexes, must not exceed 100. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.
  • IndexSizeBytes - Represents the total size of the index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.
  • ItemCount - Represents the number of items in the index. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

If the table is in the DELETING state, no information about indexes will be returned.

(structure)

Represents the properties of a local secondary index.

IndexName -> (string)

Represents the name of the local secondary index.

KeySchema -> (list)

The complete key schema for the local secondary index, consisting of one or more pairs of attribute names and key types:

  • HASH - partition key
  • RANGE - sort key

Note

The partition key of an item is also known as its hash attribute . The term “hash attribute” derives from DynamoDB’s usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

The sort key of an item is also known as its range attribute . The term “range attribute” derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

(structure)

Represents a single element of a key schema. A key schema specifies the attributes that make up the primary key of a table, or the key attributes of an index.

A KeySchemaElement represents exactly one attribute of the primary key. For example, a simple primary key would be represented by one KeySchemaElement (for the partition key). A composite primary key would require one KeySchemaElement for the partition key, and another KeySchemaElement for the sort key.

A KeySchemaElement must be a scalar, top-level attribute (not a nested attribute). The data type must be one of String, Number, or Binary. The attribute cannot be nested within a List or a Map.

AttributeName -> (string)

The name of a key attribute.

KeyType -> (string)

The role that this key attribute will assume:

  • HASH - partition key
  • RANGE - sort key

Note

The partition key of an item is also known as its hash attribute . The term “hash attribute” derives from DynamoDB’s usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

The sort key of an item is also known as its range attribute . The term “range attribute” derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

Projection -> (structure)

Represents attributes that are copied (projected) from the table into the global secondary index. These are in addition to the primary key attributes and index key attributes, which are automatically projected.

ProjectionType -> (string)

The set of attributes that are projected into the index:

  • KEYS_ONLY - Only the index and primary keys are projected into the index.
  • INCLUDE - In addition to the attributes described in KEYS_ONLY , the secondary index will include other non-key attributes that you specify.
  • ALL - All of the table attributes are projected into the index.

When using the DynamoDB console, ALL is selected by default.

NonKeyAttributes -> (list)

Represents the non-key attribute names which will be projected into the index.

For local secondary indexes, the total count of NonKeyAttributes summed across all of the local secondary indexes, must not exceed 100. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

(string)

IndexSizeBytes -> (long)

The total size of the specified index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

ItemCount -> (long)

The number of items in the specified index. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.

IndexArn -> (string)

The Amazon Resource Name (ARN) that uniquely identifies the index.

GlobalSecondaryIndexes -> (list)

The global secondary indexes, if any, on the table. Each index is scoped to a given partition key value. Each element is composed of:

  • Backfilling - If true, then the index is currently in the backfilling phase. Backfilling occurs only when a new global secondary index is added to the table. It is the process by which DynamoDB populates the new index with data from the table. (This attribute does not appear for indexes that were created during a CreateTable operation.) You can delete an index that is being created during the Backfilling phase when IndexStatus is set to CREATING and Backfilling is true. You can’t delete the index that is being created when IndexStatus is set to CREATING and Backfilling is false. (This attribute does not appear for indexes that were created during a CreateTable operation.)
  • IndexName - The name of the global secondary index.
  • IndexSizeBytes - The total size of the global secondary index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.
  • IndexStatus - The current status of the global secondary index:
    • CREATING - The index is being created.
    • UPDATING - The index is being updated.
    • DELETING - The index is being deleted.
    • ACTIVE - The index is ready for use.
  • ItemCount - The number of items in the global secondary index. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.
  • KeySchema - Specifies the complete index key schema. The attribute names in the key schema must be between 1 and 255 characters (inclusive). The key schema must begin with the same partition key as the table.
  • Projection - Specifies attributes that are copied (projected) from the table into the index. These are in addition to the primary key attributes and index key attributes, which are automatically projected. Each attribute specification is composed of:
    • ProjectionType - One of the following:
      • KEYS_ONLY - Only the index and primary keys are projected into the index.
      • INCLUDE - In addition to the attributes described in KEYS_ONLY , the secondary index will include other non-key attributes that you specify.
      • ALL - All of the table attributes are projected into the index.
    • NonKeyAttributes - A list of one or more non-key attribute names that are projected into the secondary index. The total count of attributes provided in NonKeyAttributes , summed across all of the secondary indexes, must not exceed 100. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.
  • ProvisionedThroughput - The provisioned throughput settings for the global secondary index, consisting of read and write capacity units, along with data about increases and decreases.

If the table is in the DELETING state, no information about indexes will be returned.

(string)

IndexStatus -> (string)

The current state of the global secondary index:

  • CREATING - The index is being created.
  • UPDATING - The index is being updated.
  • DELETING - The index is being deleted.
  • ACTIVE - The index is ready for use.

Backfilling -> (boolean)

Indicates whether the index is currently backfilling. Backfilling is the process of reading items from the table and determining whether they can be added to the index. (Not all items will qualify: For example, a partition key cannot have any duplicate values.) If an item can be added to the index, DynamoDB will do so. After all items have been processed, the backfilling operation is complete and Backfilling is false.

You can delete an index that is being created during the Backfilling phase when IndexStatus is set to CREATING and Backfilling is true. You can’t delete the index that is being created when IndexStatus is set to CREATING and Backfilling is false.

Note

For indexes that were created during a CreateTable operation, the Backfilling attribute does not appear in the DescribeTable output.

The maximum number of writes consumed per second before DynamoDB returns a ThrottlingException .

IndexSizeBytes -> (long)

The total size of the specified index, in bytes. DynamoDB updates this value approximately every six hours. Recent changes might not be reflected in this value.
