Represents all of the data describing a particular stream.



In the following list, the required parameters are described first.


The date and time when the request to create this stream was issued.

Type: Timestamp

Required: No


The key attribute(s) of the stream's DynamoDB table.

Type: Array of KeySchemaElement objects

Array Members: Minimum number of 1 item. Maximum number of 2 items.

Required: No


The shard ID of the item where the operation stopped, inclusive of the previous result set. Use this value to start a new operation, excluding this value in the new request.

If LastEvaluatedShardId is empty, then the "last page" of results has been processed and there is currently no more data to be retrieved.

If LastEvaluatedShardId is not empty, it does not necessarily mean that there is more data in the result set. The only way to know when you have reached the end of the result set is when LastEvaluatedShardId is empty.

Type: String

Length Constraints: Minimum length of 28. Maximum length of 65.

Required: No


The shards that comprise the stream.

Type: Array of Shard objects

Required: No


The Amazon Resource Name (ARN) for the stream.

Type: String

Length Constraints: Minimum length of 37. Maximum length of 1024.

Required: No


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:

  • the AWS customer ID.

  • the table name

  • the StreamLabel

Type: String

Required: No


Indicates the current status of the stream:

  • ENABLING - Streams is currently being enabled on the DynamoDB table.

  • ENABLED - the stream is enabled.

  • DISABLING - Streams is currently being disabled on the DynamoDB table.

  • DISABLED - the stream is disabled.

Type: String


Required: No

  • KEYS_ONLY - only the key attributes of items that were modified in the DynamoDB table.

  • NEW_IMAGE - entire items from the table, as they appeared after they were modified.

  • OLD_IMAGE - entire items from the table, as they appeared before they were modified.

  • NEW_AND_OLD_IMAGES - both the new and the old images of the items from the table.

Type: String


Required: No


The DynamoDB table with which the stream is associated.
