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 BinaryControls 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.
