Documentation

data Merge

Specifies a transform that merges a DynamicFrame with a staging DynamicFrame based on the specified primary keys to identify records. Duplicate records (records with the same primary keys) are not de-duplicated.

See: newMerge smart constructor.

Constructors

Merge'

Fields

• name :: Text

  The data inputs identified by their node names.

• source :: Text

  The source DynamicFrame that will be merged with a staging DynamicFrame.

• primaryKeys :: [[Text]]

  The list of primary key fields to match records from the source and staging dynamic frames.

Arguments

:: Text

$sel:name:Merge'

-> NonEmpty Text

$sel:inputs:Merge'

-> Text

$sel:source:Merge'

-> Merge

Create a value of Merge 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:name:Merge', merge_name - The name of the transform node.

$sel:inputs:Merge', merge_inputs - The data inputs identified by their node names.

$sel:source:Merge', merge_source - The source DynamicFrame that will be merged with a staging DynamicFrame.

$sel:primaryKeys:Merge', merge_primaryKeys - The list of primary key fields to match records from the source and staging dynamic frames.

merge_name :: Lens' Merge Text

The name of the transform node.

merge_inputs :: Lens' Merge (NonEmpty Text)

The data inputs identified by their node names.

merge_source :: Lens' Merge Text

The source DynamicFrame that will be merged with a staging DynamicFrame.

merge_primaryKeys :: Lens' Merge [[Text]]

The list of primary key fields to match records from the source and staging dynamic frames.
