Method Detail

streamEnabled

public final Boolean streamEnabled()

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

Returns:

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

streamViewType

public final StreamViewType 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.

If the service returns an enum value that is not available in the current SDK version, streamViewType will return StreamViewType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from streamViewTypeAsString().

Returns:

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.

streamViewTypeAsString

public final String streamViewTypeAsString()

• 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.

If the service returns an enum value that is not available in the current SDK version, streamViewType will return StreamViewType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from streamViewTypeAsString().

Returns:
