Description

Synopsis

data StreamSpecification = StreamSpecification' {
- streamViewType :: Maybe StreamViewType
- streamEnabled :: Bool
}
newStreamSpecification :: Bool -> StreamSpecification
streamSpecification_streamViewType :: Lens' StreamSpecification (Maybe StreamViewType)
streamSpecification_streamEnabled :: Lens' StreamSpecification Bool

Documentation

data StreamSpecification Source #

Represents the DynamoDB Streams configuration for a table in DynamoDB.

See: newStreamSpecification smart constructor.

StreamSpecification'

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) Source #

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 Source #

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