An array of attributes that describe the key schema for the table and indexes. If you are adding a new global secondary index to the table, AttributeDefinitions must include the key element(s) of the new index.
Represents an attribute for describing the key schema for the table and indexes.
A name for the attribute.
The data type for the attribute, where:
S - the attribute is of type StringN - the attribute is of type NumberB - the attribute is of type Binary[REQUIRED]
The name of the table to be updated.
Controls how you are charged for read and write throughput and how you manage capacity. When switching from pay-per-request to provisioned capacity, initial provisioned capacity values must be set. The initial provisioned capacity values are estimated based on the consumed read and write capacity of your table and global secondary indexes over the past 30 minutes.
PROVISIONED - We recommend using PROVISIONED for predictable workloads. PROVISIONED sets the billing mode to Provisioned Mode.PAY_PER_REQUEST - We recommend using PAY_PER_REQUEST for unpredictable workloads. PAY_PER_REQUEST sets the billing mode to On-Demand Mode.The new provisioned throughput settings for the specified table or index.
The maximum number of strongly consistent reads consumed per second before DynamoDB returns a ThrottlingException . For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide .
If read/write capacity mode is PAY_PER_REQUEST the value is set to 0.
The maximum number of writes consumed per second before DynamoDB returns a ThrottlingException . For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide .
If read/write capacity mode is PAY_PER_REQUEST the value is set to 0.
An array of one or more global secondary indexes for the table. For each index in the array, you can request one action:
Create - add a new global secondary index to the table.Update - modify the provisioned throughput settings of an existing global secondary index.Delete - remove a global secondary index from the table.You can create or delete only one global secondary index per UpdateTable operation.
For more information, see Managing Global Secondary Indexes in the Amazon DynamoDB Developer Guide .
Represents one of the following:
The name of an existing global secondary index, along with new provisioned throughput settings to be applied to that index.
The name of the global secondary index to be updated.
Represents the provisioned throughput settings for the specified global secondary index.
For current minimum and maximum provisioned throughput values, see Service, Account, and Table Quotas in the Amazon DynamoDB Developer Guide .
The maximum number of strongly consistent reads consumed per second before DynamoDB returns a ThrottlingException . For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide .
If read/write capacity mode is PAY_PER_REQUEST the value is set to 0.
The maximum number of writes consumed per second before DynamoDB returns a ThrottlingException . For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide .
If read/write capacity mode is PAY_PER_REQUEST the value is set to 0.
The parameters required for creating a global secondary index on an existing table:
IndexNameKeySchemaAttributeDefinitionsProjectionProvisionedThroughputThe name of the global secondary index to be created.
The key schema for the global secondary index.
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.
The name of a key attribute.
The role that this key attribute will assume:
HASH - partition keyRANGE - sort keyNote
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.
Represents attributes that are copied (projected) from the table into an index. These are in addition to the primary key attributes and index key attributes, which are automatically projected.
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.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.
Represents the provisioned throughput settings for the specified global secondary index.
For current minimum and maximum provisioned throughput values, see Service, Account, and Table Quotas in the Amazon DynamoDB Developer Guide .
The maximum number of strongly consistent reads consumed per second before DynamoDB returns a ThrottlingException . For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide .
If read/write capacity mode is PAY_PER_REQUEST the value is set to 0.
The maximum number of writes consumed per second before DynamoDB returns a ThrottlingException . For more information, see Specifying Read and Write Requirements in the Amazon DynamoDB Developer Guide .
If read/write capacity mode is PAY_PER_REQUEST the value is set to 0.
The name of an existing global secondary index to be removed.
The name of the global secondary index to be deleted.
Represents the DynamoDB Streams configuration for the table.
Note
You receive a ResourceInUseException if you try to enable a stream on a table that already has a stream, or if you try to disable a stream on a table that doesn't have a stream.
Indicates whether DynamoDB Streams is enabled (true) or disabled (false) on the table.
When an item in the table is modified, StreamViewType determines what information is written to the stream for this table. Valid values for StreamViewType are:
KEYS_ONLY - Only the key attributes of the modified item are written to the stream.NEW_IMAGE - The entire item, as it appears after it was modified, is written to the stream.OLD_IMAGE - The entire item, as it appeared before it was modified, is written to the stream.NEW_AND_OLD_IMAGES - Both the new and the old item images of the item are written to the stream.The new server-side encryption settings for the specified table.
Indicates whether server-side encryption is done using an Amazon Web Services managed key or an Amazon Web Services owned key. If enabled (true), server-side encryption type is set to KMS and an Amazon Web Services managed key is used (KMS charges apply). If disabled (false) or not specified, server-side encryption is set to Amazon Web Services owned key.
Server-side encryption type. The only supported value is:
KMS - Server-side encryption that uses Key Management Service. The key is stored in your account and is managed by KMS (KMS charges apply).The KMS key that should be used for the KMS encryption. To specify a key, use its key ID, Amazon Resource Name (ARN), alias name, or alias ARN. Note that you should only provide this parameter if the key is different from the default DynamoDB key alias/aws/dynamodb .
A list of replica update actions (create, delete, or update) for the table.
Note
This property only applies to Version 2019.11.21 (Current) of global tables.
Represents one of the following:
CreateTableReplica action in the destination Region.UpdateTable action in the destination Region.DeleteTableReplica action in the destination Region, deleting the replica and all if its items in the destination Region.Note
When you manually remove a table or global table replica, you do not automatically remove any associated scalable targets, scaling policies, or CloudWatch alarms.
The parameters required for creating a replica for the table.
The Region where the new replica will be created.
The KMS key that should be used for KMS encryption in the new replica. To specify a key, use its key ID, Amazon Resource Name (ARN), alias name, or alias ARN. Note that you should only provide this parameter if the key is different from the default DynamoDB KMS key alias/aws/dynamodb .

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 (dict) --
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.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.
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.
ProvisionedThroughput (dict) --
Represents the provisioned throughput settings for the specified global secondary index.
For current minimum and maximum provisioned throughput values, see Service, Account, and Table Quotas in the Amazon DynamoDB Developer Guide .
LastIncreaseDateTime (datetime) --
The date and time of the last provisioned throughput increase for this table.
LastDecreaseDateTime (datetime) --
The date and time of the last provisioned throughput decrease for this table.
NumberOfDecreasesToday (integer) --
The number of provisioned throughput decreases for this table during this UTC calendar day. For current maximums on provisioned throughput decreases, see Service, Account, and Table Quotas in the Amazon DynamoDB Developer Guide .
ReadCapacityUnits (integer) --
The maximum number of strongly consistent reads consumed per second before DynamoDB returns a ThrottlingException . 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 (integer) --
The maximum number of writes consumed per second before DynamoDB returns a ThrottlingException .
IndexSizeBytes (integer) --
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 (integer) --
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.
StreamSpecification (dict) --
The current DynamoDB Streams configuration for the table.
StreamEnabled (boolean) --
Indicates whether DynamoDB Streams is enabled (true) or disabled (false) on the table.
StreamViewType (string) --
When an item in the table is modified, StreamViewType determines what information is written to the stream for this table. Valid values for StreamViewType are:
KEYS_ONLY - Only the key attributes of the modified item are written to the stream.NEW_IMAGE - The entire item, as it appears after it was modified, is written to the stream.OLD_IMAGE - The entire item, as it appeared before it was modified, is written to the stream.NEW_AND_OLD_IMAGES - Both the new and the old item images of the item are written to the stream.LatestStreamLabel (string) --
A timestamp, in ISO 8601 format, for this stream.
Note that LatestStreamLabel is not a unique identifier for the stream, because it is possible that a stream from another table might have the same timestamp. However, the combination of the following three elements is guaranteed to be unique:
StreamLabelLatestStreamArn (string) --
The Amazon Resource Name (ARN) that uniquely identifies the latest stream for this table.
GlobalTableVersion (string) --
Represents the version of global tables in use, if the table is replicated across Amazon Web Services Regions.

ReplicaStatus (string) --
The current state of the replica:
CREATING - The replica is being created.UPDATING - The replica is being updated.DELETING - The replica is being deleted.ACTIVE - The replica is ready for use.REGION_DISABLED - The replica is inaccessible because the Amazon Web Services Region has been disabled.Note
If the Amazon Web Services Region remains inaccessible for more than 20 hours, DynamoDB will remove this replica from the replication group. The replica will not be deleted and replication will stop from and to this region.
INACCESSIBLE_ENCRYPTION_CREDENTIALS - The KMS key used to encrypt the table is inaccessible.Note
If the KMS key remains inaccessible for more than 20 hours, DynamoDB will remove this replica from the replication group. The replica will not be deleted and replication will stop from and to this region.
