Fields

• streamViewType :: Maybe StreamViewType

  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.
• streamEnabled :: Bool

  Indicates whether DynamoDB Streams is enabled (true) or disabled (false) on the table.

Arguments

:: Bool

$sel:streamEnabled:StreamSpecification'

-> StreamSpecification

Create a value of StreamSpecification 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:streamViewType:StreamSpecification', streamSpecification_streamViewType - 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.

$sel:streamEnabled:StreamSpecification', streamSpecification_streamEnabled - Indicates whether DynamoDB Streams is enabled (true) or disabled (false) on the table.

streamSpecification_streamViewType :: Lens' StreamSpecification (Maybe StreamViewType)

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.

streamSpecification_streamEnabled :: Lens' StreamSpecification Bool

Indicates whether DynamoDB Streams is enabled (true) or disabled (false) on the table.
