Use this Snap to bulk load data into PostgreSQL tables. If the target table does not exist PostgreSQL, you also have the provision to create the table. 
This Snap supports both binary and document inputs. You can configure the input view in the Views tab.
Additionally, this Snap supports a maximum of two input streams which is useful in sending table schema to the Snap if the target table does not exist. You can mix and match binary and document input views based on the input type.

Troubleshooting
None.

| The data to be loaded into the PostgreSQL table. This Snap has one document input view by default. A second view can be added for metadata for the table as a binary or document stream so that the target absent table can be created in the database with a similar schema as the source table. This schema is usually from the output of a database Select Snap.

| Output | Document |
|
| The Snap outputs one document specifying the status, with the records count that are being inserted into the table. Any error occurring during the process is routed to the error view. |
