data Slice Source #

Slice is the primary constraint in a Query command, per AWS requirements.

All Query commands must specify a hash attribute via DEq and optionally provide a secondary range attribute.

Constructors

Slice 

Fields

  • sliceHash :: Attribute

    Hash value of the primary key or index being used

  • sliceCond :: Maybe Condition

    An optional condition specified on the range component, if present, of the primary key or index being used.
