Documentation

data Join Source #

Specifies a transform that joins two datasets into one dataset using a comparison phrase on the specified data property keys. You can use inner, outer, left, right, left semi, and left anti joins.

See: newJoin smart constructor.

Constructors

Join'
Fields name :: Text The name of the transform node. inputs :: NonEmpty Text The data inputs identified by their node names. joinType :: JoinType Specifies the type of join to be performed on the datasets. columns :: NonEmpty JoinColumn A list of the two columns to be joined.

Arguments

:: Text	`$sel:name:Join'`
-> NonEmpty Text	`$sel:inputs:Join'`
-> JoinType	`$sel:joinType:Join'`
-> NonEmpty JoinColumn	`$sel:columns:Join'`
-> Join

Create a value of Join 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:Join', join_name - The name of the transform node.

$sel:inputs:Join', join_inputs - The data inputs identified by their node names.

$sel:joinType:Join', join_joinType - Specifies the type of join to be performed on the datasets.

$sel:columns:Join', join_columns - A list of the two columns to be joined.

join_name :: Lens' Join Text Source #

The name of the transform node.

join_inputs :: Lens' Join (NonEmpty Text) Source #

The data inputs identified by their node names.

join_joinType :: Lens' Join JoinType Source #

Specifies the type of join to be performed on the datasets.

join_columns :: Lens' Join (NonEmpty JoinColumn) Source #

A list of the two columns to be joined.
