Description

Synopsis

data Merge = Merge' {
- name :: Text
- inputs :: NonEmpty Text
- source :: Text
- primaryKeys :: [[Text]]
}
newMerge :: Text -> NonEmpty Text -> Text -> Merge
merge_name :: Lens' Merge Text

merge_source :: Lens' Merge Text
merge_primaryKeys :: Lens' Merge [[Text]]

Documentation

data Merge Source #

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 name of the transform node. inputs :: NonEmpty 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 Source #

The name of the transform node.

merge_inputs :: Lens' Merge (NonEmpty Text) Source #

The data inputs identified by their node names.

merge_source :: Lens' Merge Text Source #

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

merge_primaryKeys :: Lens' Merge [[Text]] Source #

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