data GetItem = GetItem {
- giTableName :: Text
- giKey :: PrimaryKey
- giAttrs :: Maybe [Text]
- giConsistent :: Bool
- giRetCons :: ReturnConsumption
}
getItem :: Text -> PrimaryKey -> GetItem
data GetItemResponse = GetItemResponse {
- girItem :: Maybe Item
- girConsumed :: Maybe ConsumedCapacity
}

Documentation

data GetItem Source #

A GetItem query that fetches a specific object from DDB.

See: http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/API_GetItem.html
