Documentation

data Stream

Represents all of the data describing a particular stream.

See: newStream smart constructor.

Constructors

Stream'

Fields

• streamArn :: Maybe Text

  The Amazon Resource Name (ARN) for the stream.

• streamLabel :: Maybe Text

  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
• tableName :: Maybe Text

  The DynamoDB table with which the stream is associated.

newStream :: Stream

Create a value of Stream with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:streamArn:Stream', stream_streamArn - The Amazon Resource Name (ARN) for the stream.

$sel:streamLabel:Stream', stream_streamLabel - 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

$sel:tableName:Stream', stream_tableName - The DynamoDB table with which the stream is associated.

stream_streamArn :: Lens' Stream (Maybe Text)

The Amazon Resource Name (ARN) for the stream.

stream_streamLabel :: Lens' Stream (Maybe Text)

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

stream_tableName :: Lens' Stream (Maybe Text)

The DynamoDB table with which the stream is associated.
