Mapping tasks with Google Cloud Spanner overview

Use the Data Integration Mapping Designer to create a mapping. When you create a mapping, you configure a source or a target to represent a Google Cloud Spanner table.
Validate the mapping and describe the flow of data from source and target along with the required transformations before the Secure Agent writes data to the Google Cloud Spanner target. Use the Mapping Task wizard to create a mapping task and select the mapping that you configured. The mapping task processes data based on the data flow logic you define in the mapping. Run the mapping task to read data from or write data to a Google Cloud Spanner table.
