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.

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.
