Amazonka.SDB.DeleteAttributes
Description
Deletes one or more attributes associated with an item. If all attributes of the item are deleted, the item is deleted.
DeleteAttributes
is an idempotent operation; running it multiple times
on the same item or attribute does not result in an error response.
Because Amazon SimpleDB makes multiple copies of item data and uses an
eventual consistency update model, performing a GetAttributes or Select
operation (read) immediately after a DeleteAttributes
or PutAttributes
operation (write) might not return updated item data.
Synopsis
- data DeleteAttributes = DeleteAttributes' {
- attributes :: Maybe [Attribute]
- expected :: Maybe UpdateCondition
- domainName :: Text
- itemName :: Text
- newDeleteAttributes :: Text -> Text -> DeleteAttributes
- deleteAttributes_attributes :: Lens' DeleteAttributes (Maybe [Attribute])
- deleteAttributes_expected :: Lens' DeleteAttributes (Maybe UpdateCondition)
- deleteAttributes_domainName :: Lens' DeleteAttributes Text
- deleteAttributes_itemName :: Lens' DeleteAttributes Text
- data DeleteAttributesResponse = DeleteAttributesResponse' {
- newDeleteAttributesResponse :: DeleteAttributesResponse

Create a value of DeleteAttributes
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:attributes:DeleteAttributes'
, deleteAttributes_attributes
- A list of Attributes. Similar to columns on a spreadsheet, attributes
represent categories of data that can be assigned to items.
$sel:expected:DeleteAttributes'
, deleteAttributes_expected
- The update condition which, if specified, determines whether the
specified attributes will be deleted or not. The update condition must
be satisfied in order for this request to be processed and the
attributes to be deleted.
$sel:domainName:DeleteAttributes'
, deleteAttributes_domainName
- The name of the domain in which to perform the operation.
$sel:itemName:DeleteAttributes'
, deleteAttributes_itemName
- The name of the item. Similar to rows on a spreadsheet, items represent
individual objects that contain one or more value-attribute pairs.
