Aws.DynamoDb.Commands.Scan

Description

Implementation of Amazon DynamoDb Scan command.

See: http://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_Scan.html

Synopsis

data Scan = Scan {
- sTableName :: Text
- sConsistentRead :: Bool
- sFilter :: Conditions
- sStartKey :: Maybe [Attribute]
- sLimit :: Maybe Int
- sIndex :: Maybe Text
- sSelect :: QuerySelect
- sRetCons :: ReturnConsumption
- sSegment :: Int
- sTotalSegments :: Int
}
scan :: Text -> Scan
data ScanResponse = ScanResponse {
- srItems :: Vector Item
- srLastKey :: Maybe [Attribute]
- srCount :: Int
- srScanned :: Int
- srConsumed :: Maybe ConsumedCapacity
}

Documentation

data Scan Source #

A Scan command that uses primary keys for an expedient scan.

Constructors

Scan

Fields

sTableName :: Text
Required.
sConsistentRead :: Bool
Whether to require a consistent read
sFilter :: Conditions
Whether to filter results before returning to client
sStartKey :: Maybe [Attribute]
Exclusive start key to resume a previous query.
sLimit :: Maybe Int
Whether to limit result set size
sIndex :: Maybe Text
Optional. Index to Scan
sSelect :: QuerySelect
What to return from Scan
sRetCons :: ReturnConsumption
sSegment :: Int
Segment number, starting at 0, for parallel queries.
sTotalSegments :: Int
Total number of parallel segments. 1 means sequential scan.
